I managed to run a python script FLASH.py and ImageConvertor565
.
in the FLASH .py scripts can I put COM.1 as default port to communicate with PIC chip?


On which the port and pin I connects serial communication between PC and PIC

PIC RX-pin is ?
PIC TX-pin is ?

What is the maximum number of buttons possible to make the TFT screen.

I tried to make a four keys and the fourth button is not working. The first three are working.

here's the code for PIC18F4520 that I use:
