16f628a use a6 as output
PostPosted: Sun Nov 21, 2010 11:56 am     Reply with quote
Hi I'm using int osc in 16f628a. I want to use A6 for led (output).

Physically my circuit is ok. When I powered up, my led light right away. If I do reset, MCLR led goes off. When unpress mclr, goes on and stays on all time. I tried two 16F628a - same problem. I tried output_low(LED1) in my program...same thing. Do I have to define A6 as output? Question

Thanks for help..again... Exclamation

Please show us your 'fuses' line.....
Hint...

In order to use A6 as an I/O pin it must be configured using the fuses options...
