Computer driver problem or voltage problem ?
I have programmed the right code to my pic16f877a, I can use putc/printf function but I failed to use getch function.
I couldn't receive any data from pc to my PIC16f877a when using my own computer but when I used my friend's computer, it can transmit the data from his PC to my PIC16f877a.
I have using max 232 IC, rs232 db9 femal pin, and also usb to rs232 converter.
The circuits and the coding are the same.
So, what will be the problems?
thanks
