this is code i have begun to write for what will be a learning robot
controlled by the pic18f452, the code complies and is written to the pic
without major trouble but when i insert it to the robot there is no outputs
as if the pic isnt reading anything, i think i may have a configuration
problem but i cant see anything obviously wrong, does see anything that may
help?
