IŽm a similar problem.
The outputs in a 16f690 controlled by HIGH command dŽont work fine.

This simpy code present the follw voltages in the pins of 16F690 pic.


Code:
inicio:

 
High PORTC.5    
High PORTC.4     
High PORTC.3 

High PORTC.6     
High PORTC.7  
High PORTB.7 

GOTO inicio


VCC Values:

PORTC.5 = 5V
PORTC.4 = 5V
PORTC.3 = 5V

PORTC.6 = 0.6V
PORTC.7 = 1.8V
PORTB.7 = 5V
