Hi,
I am working in a project that capture the data from keyboard using pic16f877 and store then display in LCD. I connect the keyboard clock to RB0 and keyboard data to RA0 (assigned as digital I/O). Please help me to give some idea to write code . Thanks.
Please help to answer, how to handle the keyboard code,
when we press the keyboard key, it will generate make code,
when we release the keyboard key , it will generate break code.
key pressed: A.
make code: 1C.
key released : break code F0, 1C.
My question is how you read these three codes and assign the data.
need to read only make code (1C) or read both make code and break code.
Thanks.
