PICDEM Z Demonstration Kit Overview
Features on the PICDEM Z demonstration board include:
1.
Microcontroller Socket (U4): 40- and 28-pin DIP sockets are provided for the user’s choice of Microchip PIC18 microcontrollers. The board is equipped from the factory with a PIC18LF4620 high-performance microcontroller, clocked at
4 MHz and preprogrammed with the demo application firmware using the
Microchip Stack. The microcontroller on each board included in the demonstration kit contains a label that identifies it as either a ZigBee Coordinator or ZigBee RFD.
2.
Temperature Sensor (U3: TC77): This is a 5-pin thermal sensor with an SPI interface from Microchip.
3.
User-defined LEDs (D1, D2): These two LEDs are driven by digital I/O pins of the controller, and may be used to simulate a digital output to an embedded device. These LEDs are enabled/disabled by jumpers JP2 and JP3. By default,
LEDs are enabled by permanently shorting jumpers via PCB traces. If required, you may cut the traces and install your own jumpers.
4.
User-defined Push Buttons (S2, S3): These switches are connected to digital
I/O pins on the controller, and may be used to simulate a digital input in an embedded application. These switches do not have external pull-up resistors; as a result you must enable the internal pull-up option on PORTB to correctly read the switch status.
5.
Reset Push Button (S1): This switch is tied to the MCLR pin on the controller, and is used to reset the board.
6.
RJ-11 (six-wire) Modular Connector (J5): This connector allows the demonstration board to be connected to Microchip MPLAB ICD 2 systems for advanced microcontroller debugging and programming.
7.
RS-232 (DB9F) Connector (P1): This connector allows the demonstration board to be connected to any other board or PC serial port. The preprogrammed demo application firmware uses this connector to communicate with a PC and offer application configuration options. If required, you may disconnect the on-board
RS-232 driver circuit from the controller by breaking the PCB traces on the J3 jumper.
8.
RF Card Connector (J2): This is a common connector to connect all supported
RF cards. This connector provides +3.3V DC, an SPI bus, and a few discrete digital I/O control signals.
9.
Prototype Area: A prototype area is provided to breadboard additional circuitry for development. Connections are provided for +3.3V DC, ground, and all I/O ports of a microcontroller.
10. On-board Power: An on-board regulator provides 9V DC to 3.3V DC rated at
100 mA. The board may be powered via either an external 9V DC input (J1) or the on-board 9V battery (B1). The board contains a diode to protect against an accidental reverse power connection. When using a 9V battery to power the board, switch S7 must be set to ON. The 2.5 mm 9V DC jack is wired such that when a 9V DC plug is inserted, the on-board battery is automatically disconnected from the circuit.
11. Measure Current (JP4): This jumper can be used to measure current drawn by all of the circuits on the board. By default, this jumper is shorted via a PCB trace.
To measure the current, cut the JP4 trace and insert an ammeter between the
JP4 terminals. You may also install your choice of resistor at R9 and measure voltage across it to determine the current.
12. Node ID: This unique serial number is used by the preprogrammed demonstration application firmware to create a unique 64-bit extended Medium
Access Control (MAC) address. The extended MAC address of the board can be changed by either serial configuration or by modifying firmware.
13. Revision Level Indicator (Back Side): The text on the solder side of the board indicates the hardware revision level.

2.4
EXECUTING PREPROGRAMMED DEMO APPLICATIONS
In order to observe full functionality of the demo applications, you must have one demo
Coordinator node and one demo RFD node with similar RF cards. As discussed later in this document, you may reconfigure boards such that you may use more than one
RFD node.
The preprogrammed demo Coordinator and RFD applications implement a custom remote control switch and LED application. For more information about these demo applications, please refer to the Microchip application note AN965, Microchip Stack for the ZigBee™ Protocol (DS00965).
The demo applications are completely stand-alone and do not require an interface to a host computer. However, if you have access to a host computer, you may use it to observe the activity logs of the applications. An interface to a host computer is useful to understand and troubleshoot any setup issues you might have.
Do the following to execute a preprogrammed demo application:
1.
Make sure that you have assembled each node by plugging the RF card into the motherboard.
2.
Remove power from both boards, if it was previously applied.
3.
Locate the Coordinator node by looking for the “COORD…” label on the controller.
4.
Optional: Connect the Coordinator node to a PC serial port and launch your favorite terminal program. Select the appropriate COM port and set it to 19200 bps, 8-N-1, no flow control.
5.
Apply power to the Coordinator node. Observe that both D1 and D2 flash simultaneously, followed by D2 flashing by itself. If connected to a PC, observe that the terminal program displays the message “New network successfully started
”.
6.
Now locate the RFD node by looking for the “RFD…” label on the controller.
7.
Optional: Connect the RFD node to a PC serial port and launch your favorite terminal program. Select the appropriate COM port and set it to 19200 bps,
8-N-1, no flow control.
8.
While keeping the Coordinator node still powered, apply power to the RFD node.
Observe that both LEDs D1 and D2 flash simultaneously, followed by multiple flashes of D2. If connected to a PC, observe that in one to two seconds, the terminal program displays the message “Rejoin successful”. If you do not see any message or see the message “Rejoin failed”, make sure that you have the Coordinator node powered and running properly; reset the RFD node and try again.
9.
At this point, the RFD node has successfully associated with the Coordinator node.
10. Press S2 on the RFD node and observe that D1 on the Coordinator node switches on/off.
11. Press S2 on the Coordinator and observe that D1 on the RFD node switches on/off. When you press S2 on the Coordinator, the D1 on the RFD node will toggle after few moments. This delay occurs due to the frequency at which the RFD node polls the Coordinator node.
Note: The actual radio range for the PICDEM Z nodes depends on the type of RF card and antenna in use. Please refer to the user’s guide of the respective
RF card for range information.

Chapter 3. Experimenting with the PICDEM Z Demonstration Kit
3.1
INTRODUCTION
Topics covered in this chapter include:
• Modifying Demo Application Configurations
• Modifying the Hardware Configuration
• Creating Your Application Source File
3.2
MODIFYING DEMO APPLICATION CONFIGURATIONS
The preprogrammed demo applications are factory configured with certain configurations such as node identifier, network association and binding information. If required, you may easily change these configurations through a PC running a standard RS-232 terminal program or via a stand-alone binding process.
The Demo Coordinator and Demo RFD applications use a similar terminal interface with minor differences in available configuration options. Some of the options require the use of standard terminal software, while other options are performed by a sequence of switch presses without the need for terminal software. To be able to perform the terminal-dependent steps, you must have access to at least one RS-232 (DB9, male-to-female) cable, a host computer with at least one serial port available and a standard serial terminal program.
3.2.1
Modifying Node ID Values
As specified in the IEEE 802.15.4 specification, each ZigBee node must contain a unique 64-bit MAC address value. One part of the 64-bit address consists of a 24-bit
IEEE assigned Organization Unique Identifier (OUI) and the other a 40-bit organization assigned number. The PICDEM Z demo applications create a complete MAC address by combining the Microchip OUI of 00-04-a3 and zero padded 16-bits of the node ID value label found on the board. The node ID value is stored in the microcontroller Flash memory. The PICDEM Z boards are factory-configured with their respective node ID values. If required, you may easily change the node ID values by performing the steps that follow.

3.2.2
Modifying Association and Binding Configurations
The PICDEM Z nodes are factory-configured with the following settings:
1.
The demo RFD node is associated with the demo Coordinator node.
2.
Switch S2 on the demo RFD node is bound to LED D1 on the demo Coordinator node.
3.
Switch S2 on the demo Coordinator node is bound to LED D1 on the demo RFD node.
It is these configurations that allow you to press S2 on one node and control LED D1 on the other node. If required, you may easily modify these configurations using the custom binding procedure implemented in the demo applications. For example, you may bind S2 on RFD node to D1 on the same node or on another RFD node (assuming that you have more than one RFD node).
Although the following procedure does not require a PC, you may use one to observe the setup messages displayed by the demo applications. These messages are useful to understand and troubleshoot setup issues. You may view the setup messages using a terminal program set to 19200 bps, 8-N-1, no flow control.
Do the following to modify association and binding configurations:
1.
Remove power from all nodes.
2.
Apply power to the Coordinator node (a node with a “COORD…” label on its controller) without pressing any switches, or if already powered, simply reset the board by pressing the Reset switch. This puts the demo Coordinator node in the normal mode of operation. Observe that D1 and D2 flash momentarily followed by a brief flash of D2. If connected to a terminal program, note that the message
“New network successfully started” is displayed. If you see an error message, it means that the demo Coordinator could not find an empty RF channel.
3.
While keeping the Coordinator node powered up, apply power to the RFD node
(a node with the “RFD…” label on its controller) while holding the S3 switch, or press and hold both the Reset and S3 switches; then release the Reset switch.
Observe that D1 and D2 are on. If connected to a terminal program, note that the configuration menu is displayed.
4.
If you have more than one RFD node, you may continue step 3 for each RFD node.
5.
Press S2 on the RFD node to begin the association sequence with the
Coordinator. If connected to a terminal program, note that the message
“Successfully associated” is displayed. If you do not see this message, make sure that the demo Coordinator node is powered and running in normal mode. If your computer has two serial ports and the demo Coordinator node is still connected to the computer, note that the terminal displays the message “A new node has just joined
”.
6.
If you have more than one RFD node, press S2 on each RFD node to associate them to the Coordinator node.
7.
Since there are many different possible combinations of binding a configuration,
Table 3-1 is used to describe the necessary sequence of steps for each
combination:

Note: As each step is performed, LEDs D1 and D2 on the respective node will be toggled between on and off, to off and on. Also note that the terminal program connected to the RFD node displays the message “Attempting to bind...
” and the terminal connected to the Coordinator node displays the
“Received valid...” message.
To complete the binding process, you must perform both “To Bind Switch
S2 On” and “To Bind LED D1 On” actions.
8.
Press the Reset switch on each RFD node to begin normal execution. If connected to a terminal program, note that the message “Rejoin successful
” is displayed.
9.
Depending on how binding was performed, press S2 on one node to confirm that
D1 on the same or other node toggles.
Note: To successfully control D1 on the same or other node, the Coordinator node must be powered and running in normal mode.

DEVELOPING YOUR APPLICATION
The PICDEM Z kit is shipped with complete source files for the Microchip Stack for the
ZigBee protocol. Please refer to the Microchip application note AN965 (DS00965) for detailed information. Microchip is committed to continually improve and add new features to the existing version of the Microchip Stack. Please check the Microchip web site for the latest revision of the Microchip Stack source files.
3.6
CREATING YOUR APPLICATION SOURCE FILE
The Microchip Stack includes source files for both the demo Coordinator and RFD applications. You may either modify one of the demo applications to suit your application or use them as a reference to create your application. Please refer to the
Microchip application note AN965 (DS00965) for detailed instructions on how to create your own application.
3.6.1
Programming Your Application
Once you have developed your application, you must program it into one of the
PICDEM Z nodes. To facilitate easy identification of the Coordinator and RFD node, it is recommended that you program your Coordinator and RFD application into the respective node only. However, note that all PICDEM Z motherboards are exactly the same and can be programmed to run Coordinator, RFD or FFD applications.
The PICDEM Z kit does not include the tools for clearing and reprogramming the microcontroller. To do this, you must use an appropriate device programmer. You may also use the MPLAB ICD 2 Development System, which provides a complete development suite for device debugging and programming. The PICDEM Z motherboard contains a modular connector to connect MPLAB ICD 2, PRO MATE and other compatible programmers.
Use the following configuration options when programming the microcontroller:
1.
HS-PLL (or HS) Oscillator Mode depending on your application requirement
2.
Watchdog Timer Disabled (Demo applications use software enabled Watchdog)
3.
Low-Voltage Programming Disabled
4.
All other options should be changed as per your requirements

3.6.2
Restoring Demo Firmware
You may restore the original demo firmware by reprogramming and reconfiguring the
PICDEM Z node. You may either use the factory built hex file or a rebuilt hex file to program the microcontroller. The factory built hex file is available in the PICDEM Z
Software CD.
Use the file DemoCoordApp.hex for the Demo Coordinator application, and
DemoRFDApp.hex
for the Demo RFD application. If you want to rebuild the demo firmware, please refer to the Microchip application note AN965 (DS00965) for detailed instructions. The demo firmware is embedded with the necessary PICmicro configuration options appropriate for the PICDEM Z hardware. You must have access to a compatible PICmicro device programmer to program the on-board microcontroller.
Since the configuration information such as node ID, association and binding information are stored in on-chip Flash memory, reprogramming a microcontroller requires that you reconfigure each node before you can observe demo application functionality. A newly programmed board will automatically enter into configuration
mode. Refer to Section 3.2 “Modifying Demo Application Configurations” for a
detailed procedure for reconfiguring the applications.

B.7.1
Introduction
This section covers the following topics:
• Using the PICDEM Z 2.4 GHz RF Card for the First Time
B.7.2
Motherboard Requirements
The PICDEM Z 2.4 GHz RF card is designed for use with a PICDEM Z motherboard or similar board. If you are planning to use the RF card with your custom board, use the
PICDEM Z motherboard schematic as a reference (see Section A.1 “PICDEM Z
B.7.3
Using the PICDEM Z 2.4 GHz RF Card for the First Time
The PICDEM Z 2.4 GHz RF card must be properly plugged into the PICDEM Z
motherboard to complete the setup. Refer to Figure 2-1 for an example.
Perform the following steps to prepare each node:
1.
Remove from box and unwrap each board and place on a non-conductive surface.
2.
Carefully plug the PICDEM Z 2.4 GHz RF card into the J2 connector on the main board. Note that the connectors on the main board and RF card are polarized and will not allow incorrect insertion.
3.
Power the PICDEM Z motherboard. Observe that LEDs D1 and D2 have flashed.
This confirms that the boards are working properly.
Note: Before transmitting an RF signal, check with your local telecommunication authorities to ensure that no restriction on the use of the 2400-2483.5 MHz
ISM band is in effect.
The CC2420 operates in the 2.4 GHz frequency band; however, be advised that even though this band is commonly thought of as a world-wide band, some countries do not allow unlicensed operation in this band.
