Pic18f2553 Port C problems
Posted: Thu Sep 13, 2018 4:59 pm
Gents -
I,m having an issue with port C bits 4, 5, and 7. Currently using bit 6 as TX for display - Works fine
Bits 0 - 2 as I/o work fine
Can't get bits C4, C5, C7 to switch on as outputs and simply trying to beep with C4
Tried new chip, attempted different configurations for the osc - Currently using 8mhz internal
I put a simple routine to turn on and off the outputs but read nothing with a meter:
I notice that C3 is not available on this chip, and I suspect a conflict with the chip configuration. Is this something you can help me with?
