Hi,
I am suing processing 1.5 with XP 32bit and i want to do serial comm of uC using PIC16F877 with processing and tested that pic uC code in serial terminal window it is transferring 0xff and 0x02 with delay in between to see the color diff on processing window there is no error in both code but then also it is not changing window color why??
