6. HARDWARE
SK40C comes with UIC00A/B ICSP USB programmer connector to offer simple way for
downloading program.UIC00A/B ICSP programmer is very easy programming tool and helps
to save development time.
6.1 Loading Program Using UIC00A/B Programmer
●Connect SK40C as shown in following figure.
After plug in 40-pin PIC MCU (make sure the orientation is correct) of your choice, SK40C
should be powered by DC adaptor. Now, the hex code is ready to be loaded to SK40C. For
the usage of UIC00A/B, please refer to UIC00A/B User’s Manual.
RB7/PGD and RB6/PGC are two pins that being used in ICSP program loading, and have
been connected to UIC00A/B connector and 2 LED indicators. User is advised not to use
these pins as input, because the input device may affect the ICSP process. Even when using as
output, RB7 or RB6 pin is 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/B User’s Manual for further details.

●Figure below shows an example connection of SK40C to external device via UART
port. This example connection shows UART pins of SK40C (PIC16F877A) is
connected to UART pins 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.
