Problem with portA PIC16F628A (by Francisco)
I'm using PIC16F628A to active a led on portB and all outputs working very well but on portA on pins RA4, RA6 and RA7 no work... I know about external oscilator but is possible using internal oscilator. This is possible if I dissassemple e change the option but is very interressing if have a option on menu...
Great project and Thanks... Sorry if my English is not very good but I'm Brazilian.

When You program PIC for oscillator instead crystal change to:
"Oscillator" > "IntRC I/0" RA4 is open drain type (minus ON, OFF) (no +5V on that pin) when used as output.
