Sir,

I am doing a project in PIC16F877A .Here in my project,I want to collect data from ps2 key board, and it is to be displayed on LCD.But now I am facing some difficulties to lit the key board LED's individually.

To lit caps lock led, I first send 0xed ,then I received 0xfa as (ACK) from key board.After that I have send 0x04 but caps lock led doesn't glows.If I am giving command to glow any of the two combination of led's it works.


But I couldn't able to trace out where I made mistake.Can any one give me proper idea to rectify this problem.



Thanking you.
