of UIC00A, please refer to UIC00A User’s Manual.
RB7 and RB6 have been connected to UIC00A connector and 2 LED indicators. User is
advice not to use these pin as input. Even when using as output, RB7 or RB6 pin are
recommended to be used in controlling non critical device such as LED, LCD, 7 segments or
buzzer. It is recommended to isolated ICSP signals from application circuit by using series
resistor (range 220 ohm and above). Furthermore, NO capacitance component (capacitor)
should be connected to these 2 pins. Please refer to UIC00A User’s Manual for further
details.

5.4 USB Interface
USB is serial communication between microcontroller and computer. Previous Starter Kit
(SK40B) use RS232 Serial port for serial communication. RS232 is conventional way of
interfacing microcontroller to PC via serial port. Now USB is replace RS232 in serial
communication.
5.4.1 SK40C USB
USB data pins (pin 23, D- and pin 24, D+) were connected to a mini USB port on SK40C
board for USB development use. So far, Microchip has only 5 USB 8-bit microcontrollers in
40-pin PDIP package such as PIC18F4450, PIC18F4455, PIC18F4550, PIC18F4458 and
PIC18F4553. Microchip has USB software to support USB on 8-bit, 16-bit and 32-bit MCUs.
This software is royalty free source code which called MCHPFSUSB Framework and also
includes example projects. Download the appropriate USB stack for the target processor.
Each includes USB firmware for the microcontroller as well as a USB device driver for the
PC which allows the PC to treat the microcontroller as a USB device. Classes supported
include HID, CDC, MSD and generic.
User can download MCHPFSUSB Framework (Microchip Application Libraries) from
Cytron website under “Useful Document” of SK40C. Unzip it and install it after finish
download. “Microchip Solutions” folder will be created at your C Drive. All free framework
and example projects are inside the folder. For SK40C user, only the project with this name
“PICDEM FSUSB.mcp” is suitable for your project but you need do some modification on
“HardwareProfile – PICDEM FSUSB.h” because the SK40C’s switches and LEDs are
connected to different I/O pin if compare to the PICDEM FSUSB Demo Board. User can
download the PICDEM FSUSB Demo Board User’s Guide at Cytron website under “Useful
Document” of SK40C which has the schematic diagram for your reference.

5.4.2 SK40C HID USB Bootloader
Cytron Technologies has provided the SK40C HID USB Bootloader firmware (edited form
MCHPFSUSB Framework). This firmware is currently configured to work with the
PIC18F4550 using the CYTRON SK40C. However, user still can use this code for other USB
microcontroller after doing some project modification. User just loads the given appropriate
hex file to PIC by using the programmer (UIC00A). Please do remind that 8-bit USB
microcontrollers in 40-pin PDIP only PIC18F4450, PIC18F4455, PIC18F4550, PIC18F4458
and PIC18F4553. So, Cytron Technologies has provided all of the hex files for each PIC
inside the “SK40C HID Bootloader Firmware (Hex file)” folder as shown as below. Other
than that are not support this USB bootloader on SK40C board.

UART to Microcontroller
Another possible usage of UART is to communicate with another embedded system or
microcontroller. For microcontroller to interface with SK40C, the minimum requirement will
be TTL UART (Universal Asynchronous Receiver and Transmitter) and 5V supply. As for
UART, a minimum of Receiver pin is required to receive command from SK40C.
1. Following sample schematic show SK40C is interface to SKPS. This sample
schematic show UART pin of SK40C (PIC16F877A) is connecting to UART pin of
SKPS. Tx and Rx pin of SK40C should be cross connected to Tx and Rx pin of
SKPS. In other words, Tx pin of SK40C should be connected to Rx pin of SKPS,
while Rx pin of SK40C should be connected to Tx pin of SKPS. No extra component
is necessary between these connections. For details connection, please refer to sample
schematic.
