Hi,
I have setup the hardware with PIC16F877 which is deriving a display screen. I have written initialisation codes. I am using EasyPIC5 board and the MicroC program to download my C codes in the PIC16F877. This works perfectly.
Now, I have made serial connections (RS232) from a microprocessor to this PIC16F877, and I want to send instructions saying initialise the display(above) to the PIC from this microprocessor. These instructions should be sent via the RS232. I want to understand how does the PIC understand my instruction and do this? How do I setup this command in serial input stream? and write this command from the microprocessor and PIC recognise it as initialising the display?
If anyone can give me some idea or perhaps anyone has done this already could help me on this. I will appreciate it.
Thanks alot.
