Opening a HEX File
Overview
QuickWriter accepts INHX8M (INTEL HEX 8 bit merged) and INHX32 HEX files. For the PICmicro
MCU microcontroller, these are generally in one of two formats:
Microchip: Includes Code, Data, ID and Configuration Word information. This format is
normally saved with a ".hex" extension.
TechTools: Includes Code, Data, ID, Device type, Configuration Word and sometimes
Calibration information. This format is normally saved with a ".obj" extension.
QuickWriter will accept the above formats and adjust all relative data according to the type of
information found in the HEX file. Any information that is missing from the HEX file (such as the
Configuration Word) will be set to defaults unless manually overridden elsewhere in the program. If
the MCU type is not specified, then the currently selected MCU will be used.
QuickWriter saves HEX files with the ".hex" extension following Microchip's format. However, it
also includes the device type as a comment that can be read by QuickWriter. This allows other
products that may not recognize the device type to use the HEX file without experiencing any
errors.
Details
Select "FILE - Open File". Choose the desired file, then click "Open". The full filename and path
will be displayed in the Title Bar of the program, the file will be loaded into memory and all
displayed data will be updated with the contents of the HEX file.

Setting Options
Overview
Options are divided into five categories:
Auto Run Options - Enables and disables programming operations and sections of the MCU for
"Auto Run" cycles. These selections will enable or disable speed buttons and the associated
item in the "Task Tree" on the left of the main window, but will not affect the "MCU SECTION"
menu items, which will always be available while "Option Editing" is enabled in General
Options.
General Options - General options that are not normally needed during development but help
when preparing settings for production personnel.
HEX Options - Provides HEX file Overrides for the specific HEX file and selection of records to
include when saving HEX files.
Serial Numbers - Enable and set Serial Numbering details such as number of locations, area of
the MCU and address to place the serial number.
Advanced Options - Advanced settings mainly related to In-Circuit Programming.
All options are dynamic and take effect immediately when changed. It is NOT necessary to "close"
the options window or to "save option settings" in order to "apply" the new settings. QuickWriter
was designed with developers in mind and frequent option changes between programming tasks
or "auto run" cycles is expected.
Details
Option changes and Editing take effect immediately regardless of whether the Window is closed or
remains open.
Options are saved permanantly when the application is closed and when "File - Save Option
Settings" is selected.
Options are loaded whenever the application starts and when a HEX file is loaded. Options will be
restored from the HEX file and the corresponding ".QWC" (QuickWriter Control) file if found,
otherwise all options will remain unchanged from the current settings.
NOTE: Some options are Refreshed from permanent settings when the MCU selection is
changed. Be sure to save any changes to options before changing the MCU selection.

Operations:
Enable Erase - If available for the MCU and selected, a bulk erase is performed on the FLASH
device during Auto Run cycles.
Enable Blank Check - If selected, a blank check is performed on all enabled areas of the
device during Auto Run cycles. We suggest leaving this option enabled unless reprogramming
an MCU that already contains data.
Enable Verify - If selected, a verify will be performed during Auto Run cycles on all selected
areas of the MCU (i.e. Code, EE Data, Calibration, ID) before the Configuration Word is
programmed. Most programming operations automatically verify during programming, but
because some MCU algorithms do not, we suggest always leaving this option enabled.
Enable Serial Numbering - If selected, the MCU will be serialized (just prior to programming the
Configuration word) during Auto Run cycles according to the settings in Serial Number options
(also see: Using Serial Numbers).
MCU Sections:
Enable Code - If selected, the Code Space area will be blank checked, programmed and
verified during Auto Run cycles according to Operation settings.
Enable EE Data - If selected, the EE Data area will be programmed and verified during Auto
Run cycles.
Enable ID Locations - If selected, the ID locations will be blank checked, programmed and
verified during Auto Run cycles. ID locations have no bearing on the operation of the MCU and
can be ignored if desired.
Enable Calibration - If available for the MCU and selected, the Calibration area will be blank
checked, programmed and verified during Auto Run cycles. Some FLASH MCUs with calibration
require this option and QuickWriter will automatically select it for you. If the MCU is not a FLASH
device, we strongly advise against selecting this option unless programming a JW
(windowed) device. Attempting to program the calibration area of an OTP (one time
programmable) device will result in corrupted calibration data.
Enable Fuses - If selected, the Configuration Word will be programmed and verified during Auto
Run cycles.

Setting General Options
Overview
General options that are not normally needed during development but help when preparing
settings for production personnel.
Details
Misc. Options:
Skip Blank Locations - If selected, any "Blank" value will be skipped during programming,
which can greatly reduce programming time on large devices that are only using small portions
of the Code space. Keep in mind however, that after serializing an MCU in a "Blank" area of the
code space, verifying will pass because of skipping over the blank area. Likewise, blank
checking will fail because a "non-blank" value is detected. This normally is not an issue but could
be confusing when manually selecting individual programming tasks out of sequence. NOTE:
This setting has no effect on 18 series MCU's and some newer FLASH MCU's due to multi-word
programming algorithms.
Disable Task Confirmation Messages - If selected, all "Are You Sure?" type messages will be
disabled. We suggest enabling this option after you are thoroughly familiar with the programs
operation.
Warn if CODE/Data Protection is Enabled - If selected, a warning dialog will appear if the
Fuse Options are set to "Protect" any area of the MCU. (see: Setting the Configuration Word
(Fuses))
Use High Speed Transfers - Select this option to enable higher speed communication between
the PC and Quickwriter. This will double the speed of Reading from the device and may reduce
total programming time slightly on some MCU's. If any communication errors are detected while
this option is enabled, QuickWriter will automatically switch back to the normal transfer speed
until "Reset QuickWriter" is selected, a new port is selected, this option is re-selected or the
program is restarted.
Use Microchip Checksums - If selected, QuickWriter's buffer checksum calculation will adhere
to Microchip's method of calculation which does not include the EEDATA and only includes
Code and User IDs depending on the values of the Fuses and the device selected. The resulting
calculation is displayed as a 16 bit HEX value.
To match Microchip's "Code Protected" checksum value, enable this option and "Read" a code
protected device.
If not selected, QuickWriter's checksum will include all enabled buffers (Code, EEDATA, User
IDs and FUSES) and the resulting calculation is displayed as a 32 bit HEX value.

Production Control:
Disable Option Editing - When this option is selected, all access to change options is hidden
when the HEX file is opened. This prevents production personnel from accidentally changing
settings and producing "unusable" devices.
To regain access, simply choose "Edit - Enable Option Editing". Entering the correct password
will re-enable access to the options and the Editors.
If no password was specified when Option Editing was disabled, then leave the password field
blank and select "OK" to re-enable access.
Disable EE Data Editor - When this option is selected, access to the EE Data editor will be
disabled.
Disable Read Functions - If selected, all READ functions will be disabled. This will prevent
production personnel from accidentally "Reading" the MCU and possibly changing loaded data.
Open in Compact View - When this option is selected, QuickWriter will open in "Compact View"
only, regardless of the view selected previously. When this option is left unchecked, the view
state is retreived from the operator's local settings (stored in the Operating System's Registry).
Password to Enable Option Editing - If a password exists in this field and the "Disable Option
Editing" option is checked, then this password will be required to re-enable option editing when
the current HEX file is re-opened. The password is limited to 32 Alpha-Numeric characters.

Serial Number Options:
Enable Serial Numbering - If selected, the MCU will be serialized during Auto Run cycles.
Use Existing Microchip SQTP file - When selected, use the button to the left of the option to
choose an SQTP file (*.num). A log file will automatically be created with the same name but
with a "QWL" extension.
Each serial number is marked as "used" when it is retreived from the SQTP file to prevent
using the same number twice. As each number is programmed into a PICmicro MCU, the
results are stored in the log file, including Pass or Fail, the QuickWriter used, the Socket
used and the time in ms.
The SQTP file can reside anywhere on a local network as QuickWriter fully implements file
sharing mechanisms for the SQTP file and the corresponding LOG file.
Microchip SQTP files can be generated using the MPLAB environment provided by
Microchip Technology Inc. To generate this file from MPLAB, the appropriate tool (such as a
Pro version programmer) must be selected (see the Help information provided with
MPLAB). Or an equivelant HEX file can be generated manually with an identical address
specified for each HEX line.
NOTE: When this option is selected, the "Locations" and "Address" options are disabled
since this information is retreived from the SQTP file.
Place in Code Memory - If selected, the Serial number will be programmed into the Code area
of the MCU. This also enables access to the Encode as RETLW option.
Encode as RETLW - This option is only available if the CODE memory option is selected. If
selected, each Serial number location will be converted into the proper RETLW OPCODE
(return literal in W) for the currently selected MCU.
Place in EEPROM Memory - If selected, the Serial number will be programmed into the EE

DATA area of the MCU. This also Disables access to the Encode as RETLW option.
Number of Locations - Enter the maximum number of locations the serial number will need
(from 1 to 8). Each byte of the serial number will use 1 location in the memory area
specified.
Place at Address - Enter the address in the selected memory area to place the serial number.
This can be from 0 to the highest available address, minus the number of locations
specified. If an address higher than the maximum valid address is specified, QuickWriter will
notify you and automatically reduce the address to the highest valid address for the selected
memory area and number of locations.

Adjust the Programming Pulse Width of FLASH MCUs and choose Target Power Options for ICP
(In-Circuit Programming).
Details
FLASH Programming Pulse Width:
Modify this setting in "Less than Optimal" situations to ensure successful programming over
voltage, temperature, device and circuit variations.
The default value of Tmin is preset to the Factory Recommended Value that already accounts
for temperature and device variations. However if errors occur when programming In-circuit, this
value may need to be adjusted to account for Voltage and Circuit variations.
Each step in the selector (shown above) will increase the duration of the programming pulse by
1/4 of the Factory Recommended Value. The 5 steps are as follows:
PPW = Tmin or 1 PPW
PPW = (Tmin + (Tmin /4)) or 1.25 PPW
PPW = (Tmin + ((Tmin /4) * 2)) or 1.50 PPW
PPW = (Tmin + ((Tmin /4) * 3)) or 1.75 PPW
PPW = (Tmin * 2) or 2 PPW
If the calculated value exceeds factory specifications or a maximum of 255 ms, it will be
adjusted apropriately.

Setting I.D. Locations
Overview
PICmicro MCU's have four or eight ID locations reserved for the customer's use. Although each
location may be 12, 14 or 16 bits in length (depending on the MCU), the manufacturer
recommends using the 4 least significant bits of each location. Common industry practice has
offered the ability to use the 7 least significant bits of each location therefore, we provide both
options.
If your HEX file does not include ID information or you would like override the ID with a different
value whenever the HEX file is opened, select the "Override" check box after changing the ID
values.
Details
Select "Edit - ID Locations". If the values displayed do not reflect those desired, simply select and
edit the appropriate field (4 bit or 7 bit). Any changes take effect immediately and will be
implemented with the next programming action (i.e. Autorun, program ID locations, etc.).

Setting Options for Production Personnel
Overview
Sometimes it is desirable to block access to option settings for a HEX file in order to prevent
undesired changes. Whether this is for archiving "released" code or for the production department,
QuickWriter provides a simple method of protecting your settings from accidental changes. This is
accomplished through a "control" file.
The control file contains all option settings for QuickWriter, is saved in the same directory as the
HEX file and is created with the same name as the HEX file except the file extension is changed to
".QWC". One of the options in the control file instructs QuickWriter to DISABLE option editing.

QuickWriter Help 2.1
The following will be disabled when a HEX file is opened, if the "Disable Option Editing for this file"
option has been selected:
MCU selection.
Auto Options, HEX Options and General Options.
Code, FUSE, ID and Calibration editors.
Manual access to tasks in the "Programming Tasks" tree or MCU Section menu.
ALL programming functions except Auto Run, Erase, Blank Check and Verify.
A detailed procedure for setting options for production personnel is described below but the
general procedure is to Open the HEX file, set all desired options, select "Disable Option Editing"
in "General Options", then select "File - Save Option Settings". The control file has now been
created and modified (resides in the same directory as the HEX file), and is now ready for the
production department.

Open the desired HEX file from the directory it will be used in if possible.
Verify the MCU, Configuration Word and ID location settings. If the MCU and Configuration
Word are incorrect you will need to make the necessary changes, then save the HEX file
with ALL "Save Hex Options" enabled or select the proper overrides in HEX Options.
After saving the hex file, re-open it and re-verify the MCU, Configuration Word and etc. If
everything is correct, proceed with the next step.
Go to the "Options - Auto Options" and select each option to be performed during
programming. Each selected item will be performed when the production department chooses
"Auto Run" (or F4 or Alt+A).
If you have enabled Serialization, verify the serial number length and address settings to
prevent overlapping valid code or EE data. Also verify the "last serial number" and "Auto
Increment" settings (see: Using Serial Numbers).
After all settings have been verified, select "Disable Option Editing.." in the "Misc. Options"
section of the "General Options". You may also want to select "Disable Read Functions" in
this same location.
Select "File - Save Option Settings" from the main menu, then close the program.
Copy the HEX file and the corresponding control file (hexfilename.QWC) to the desired
location for production accessability. The production department can now open the HEX file
without fear of accidental changes.

4.1
Selecting the MCU
Overview
Some HEX files will not contain the MCU type or you may want to select a different MCU to
program. When the MCU type changes, QuickWriter will adjust many aspects of the software to
match the capabilities of the selected device. Because of this it is very important to select the
proper MCU type (including prefixes such as 'A','B' and etc.).
Details
Select "Options - Select MCU Type". When the MCU dialog opens use the cursor keys or the
mouse to select the desired MCU, then click the 'OK' button (or press the 'Enter' key) or
"DBL-Click" on the desired MCU.
(see also: Setting HEX Options)
Shortcuts
Alt+O, S
4.2
Setting the Configuration Word (Fuses)
Overview
The configuration Word is set according to data stored in the HEX file when it is opened. However,
you are free to change this information in the program before programming the MCU, provided
"Option Editing" is enabled for this HEX file (see: Setting General Options ; see also: Setting
Options for Production Personnel).
Specific bits in each Configuration Word control available MCU options when programmed.
QuickWriter identifies each set of bits by labels provided in the manufacturers datasheet. If you are
not familiar with a particular reference, such as WDT (Watch Dog Timer), you will need to see the
datasheet which will give a full explanation of the configuration option and its meaning. Do not
change the configuration word unless you are fully aware of each options function. Selecting the
wrong configuration can make the MCU operation undesirable or unreliable, which renders the
device unusable.
Details
Select "Edit - Configuration Word". To change FUSES in the configuration word, use the selection
arrow beside each Fuse option to select from its available settings (or use the TAB and CURSOR
keys).
WARN if Code Protection Enabled - If selected and one of the Configuration Fuses indicate that
the Code or Data Protection fuse(s) have been enabled, you will be presented with three
options before programming the MCU.
©2006 TechTools
Operation
17
This warning will help remind you that the protection fuses are about to be enabled.
Once the Code or Data protection fuses have been enabled on a device, the contents of the
protected section is no longer accessible for READING or VERIFYING.
NOTE: Code Protection will prevent erasing on most JW (Windowed, eraseble) devices.
If setting the Protection fuse was unintentional, then select NO to have QuickWriter
automatically disable the Protection and continue with the operation in progress. Otherwise
choose YES to continue "AS IS" or CANCEL to completely abort the operation.
NOTE: Each MCU has different Configuration options. If the MCU type is changed,
you will need to review changes in the Configuration Word options before
programming the MCU.
(see also: Setting HEX Options)
Special Consideration
Some PICmicro MCUs have Fuse options to "turn off" the external MCLR signal and others may
have options to set the Oscillator to "internal". On older MCUs with these options and a "Power
First" requirement of VDD (such as the 12C508/12C509), QuickWriter may have problems
re-programming or reading the contents once the fuses have been programmed. This normally
does not become an issue since the devices are OTP (one time programmable).
Newer MCUs with these fuse options allow a "Power first" of VPP (programming Voltage), which
ensures the device can re-enter programming mode and be read after the fuses have been
programmed.
During an "Auto Run" programming cycle, QuickWriter always verifies all sections of the MCU
before programming the Fuses. Programming the fuses last allows QuickWriter to perform a full
verification of all areas of the MCU regardless of the fuse settings.

Using Gang Adapters
Overview
When using Gang adapters, each device is programmed and verified independently, but at the
same time. Because of this, QuickWriter is able to save time while also tracking individual errors
that may occur for each device being programmed.
Gang adapters are available for all serially programmed devices that are supported by

QuickWriter. Multiple devices can be programmed at once without costing additional time except
for the minor delay while Serializing.

After connecting a gang adapter, you will want to enable multiple device support by selecting
multiple sockets in the QuickWriter software.
The Socket LED Indicators (shown above), will change states when "clicked" as shown below.
Socket B disabled.

Reading the MCU Contents
Overview
Sometimes it may be desirable to "reproduce" an MCU that has already been programmed or to
visually verify the contents. To do this, you will need to read the contents of the MCU instead of
opening a HEX file.
Details
To read the contents of an MCU, choose "Run - Auto Read Only" from the main menu (or Ctl+R).

If multiple sockets have been selected, a pop-up menu will appear for you to select the socket you
wish to read from. After selecting the socket, the entire contents of the MCU (including I.D.
locations and Configuration Word) will be loaded into the QuickWriter software.
Unless you intend to make exact duplicates of the MCU just read, remember to re-open the HEX
file before programming another device.

In-Circuit Programming
23
Overview
QuickWriter can be used with single socket and gang programming adapters, but one of its key
features is the ability to program devices already incorporated in a working circuit. To program
devices in-circuit, a few requirements must be met by the target.
For a detailed discussion on the key issues related to in-circuit programming, see the In-Circuit
Programming Guide installed with the QuickWriter software.
NOTE: ICP does not support parallel programmed devices (i.e. PIC16C55, PIC16C57, etc.).
Details
When using the ICP cable (provided with QuickWriter), always select Socket A. If additional
sockets are selected or if socket A is not selected, programming errors will occur.
If any error messages appear during ICP, pay special attention to any messages relating to
voltage errors. QuickWriter performs extensive voltage testing to help prevent damage to itself and
your target. All suggestions presented in the error dialog should be checked thoroughly before
another programming attempt is made.
Target Design Recommendations
Use a 10K Ohm or larger pull up on MCLR Use 10uF or less capacitance on MCLR (most
targets use none).
Avoid or isolate any other circuitry that touches the MCLR line.
Ideally, use RB6 (clock), RB7(data) and RB3 (LVP/PGM pin, RB4 or RB5 on some PICmicros)
as OUTPUTs in your circuit design OR connect them to outside-world connections or NO
switches so that nothing is driving them during programming. This avoids any need for
isolation. If that is not desirable, design to isolate or tri-state anything that drives these
lines.
Always connect the ground pin.
Decide who powers the target and address the trade-offs involved. (see: ICP with Self
Powered Targets)
When programming, enable the PICmicro MCU's power-up timer Fuse Option if possible.
Particularly if setting the device for internal MCLR or internal OSC.

ICP with Self Powered Targets
Overview
QuickWriter can supply up to 100 ma of current on the VDD signal (5 volts) when programming
MCUs in-circuit. This includes the current required by the MCU during programming (20 to 50
ma).
When programming MCUs in-circuit, it is sometimes desirable or even necessary for the circuit to
supply its own power. If the target circuit has larger current requirements or if it is not feasible to
power the circuit from the 5 volt power trace (i.e. when this will apply 5 volts to the output of a
voltage regulator), then you should choose QuickWriter's "Monitor a Self Powered Target" option.
When the circuit supplies its own power, we have to be concerned with voltage sequence and
timing requirements of the MCU.
The programming algorithms for some devices require that the device's VDD be enabled/disabled
several times during a
programming cycle. In self-powered target boards, this requires that we ask the operator to do the
power cycling for us. This can become tedious for the operator. Even with devices that only require
a single power up and down, it would still be nice to free the operator from this burden. To enable
full automation of in-circuit programming, without violating programming specs, QuickWriter
provides a control signal called TVDDEN.
Details
When using the "Self Powered Target" option, QuickWriter provides two ways of determining when
to activate your target circuits power supply.
1. Operator Notification for manual activation/deactivation.
2. Hardware Control Signal (TVDDEN) for electronic activation/deactivation (automation).
Operator Notification
When QuickWriter is ready for the target's power supply to be turned on or off, it will display a
notification dialog that includes the current voltage reading. Once the required voltage condition
is met, this dialog will automatically close and QuickWriter will continue operation.

If for some reason the voltage condition can not be met, the operator can use the ABORT button
to close the dialog. Using the abort button will cause QuickWriter to discontinue the operation
and display a relevant error message.
Hardware Control Signal (TVDDEN)
TVDDEN can be used to control your target's power supply (through an appropriate driver
circuit). QuickWriter's TVDDEN signal will help automate control of the target's power and make
it possible to meet the required timing for power sequence specifications.
TVDDEN is a new signal, available on QuickWriter's 26 pin interface connector. It is not
available in the standard ICSP cable included with the unit. You may need to customize your
in-circuit cable to make use of the new signal (and add your power control circuitry). (see: Cable
Connector)
TVDDEN is an active high, logic level (+-20ma) signal. Typically, one would use it to drive a
current limited LED within a solid-state relay to control your target's power supply.

Cable Connector
Overview
QuickWriter's programming cable connector is compatible with existing PICwriter and Parallax
PIC16CXX-PGM programmer adapters while also providing Gang programming with TechTools
Gang programming adapters and In-Circuit Programming with the included ICP Cable.
A newer signal, TVDDEN is also provided on this connector for automated control of the Target
Circuit's power supply (see: ICP with Self Powered Targets).

Command-line Operation
Overview
Sometimes it is convenient to create a shortcut that will launch the QuickWriter software with a
specific HEX file and device type, then have it program and close automatically. This can be
accomplished from a BAT file or a Window's Shortcut using QuickWriter's command-line options.
Details
Usage - QW.exe
Filename [/Ddevicename]
[/A] [/X]
Filename = [optional] - Any valid filename including drive and path. If omitted, the last file
used is opened. A Control File can also be specified (hexfilename.QWC), in which case
QuickWriter will open the associated filename stored in the Control File.
/D = Device [optional - only valid if filename specified] - requires a valid, supported MCU
number such as '18F2620'.
/A = AutoRun [optional - only valid if filename specified] - instructs the software to "Auto
Run" and close if no errors occurred.
/X = Close with Exit Code [optional - only valid if filename and /A specified] - instructs the
software to inhibit all non-critical notification dialogs during "Auto Run" and close when
finished. The program will exit with an appropriate Error Code if an error occurred.
Example 1 - QW myhexfile.obj
/D12CE673 /A
The above example will launch QuickWriter, load the hex file "myhexfile.obj" from the same
directory as the QuickWriter software, retrieve all option settings from "myhexfile.qwc" (if it
exists), set the MCU to a 12CE673 then "Auto Run" and close. If any errors occur, the
program will remain open for you to view the results. After viewing the error, you will need to
manually close the program (Alt+X, or "File - Exit" ).
Example 2 - QW C:\myprojects\Blinkleds\myhexfile.obj
The above example will launch QuickWriter, load the hex file "myhexfile.obj" from the
"C:\myprojects\Blinkleds\" directory and retrieve all option settings from "myhexfile.qwc" (if it
exists). The MCU information will be set from the Control file if that option is specified in the
control file. If the control file did not specify an MCU override, then the MCU is extracted from
the hex file if a device record is present, else the last selected MCU will be used.

5.5
Exit Codes
Overview
When the QuickWriter program terminates, an exit code is returned. This is normally ignored by
the system but can be a great benefit when programatically launching the QuickWriter program
from custom software (such as using the Window's API "ShellExecute" function). The exit codes
can be used by the lauching program to make intelligent decisions.
Details
QuickWriter's Exit Codes are returned as a 2 byte bitmask, with each bit position representing a
particular error code. A return value of 0 (zero) indicates no errors occurred.
