Hi,
Can anyone tell me what is wrong with this .TRE file, .LST file, the 16F877 mcu does not work at all, but if I remove some code it starts to work, but than I am using only 26% memory.
Also can anyone tell me if a function exceeds the segment size..

Hi,
PCM: 3.228

It compiles alright, with no errors, but does not work , while in target board.
Well here is the code.

I removed the check_rotary functions and it started to work, removing the usart_rcvr also worked...
