Usage of built-in DAC ?

[Demon]

Are you checking voltage on pin A.2?

I see nothing, as long as you're checking B.7.

What happens if you move DACCON0 after the other registers, just before DEFINE OSC?

Maybe you are disabling DAC accidentally.

Robert: ¡¡¡ PROBLEM SOLVED ¡¡¡
The power supply is 5 V. I am checking Portb.7 because I config the DACCON0 as $90.
This enable the DAC and select Portb.7 as output.
I move the DACCON0 register as you suggest,but the result is the same.
Also I do not why,PORTA.6 remains lit when is making the voltage loop.
It is configured as output and I clear the port at the begginning.
I am using the EASYPIC V7 for development,and I realize I was loading
The portb with the panel Leds. I turnoff the led selection and now all is working OK.

Thanks for your comments...

Have you tried this?

LED var LATa.7

[Demon]

Why do this?

FOR AUX = 0 TO 4
LED = 1
PORTA = 255
PORTC = 255
PAUSE 500
LED = 0
PORTA = 0
PORTC = 0
PAUSE 500
NEXT AUX

Robert:
It works... the problem with Porta.6 was configuration. It was as oscilator output.
Changing & _CLKOUTEN_ON TO & _CLKOUTEN_OFF , in _CONFIG2 ,turn off the porta,6 and then
can be used as normal i/o port.
Thanks again...

Edited: I was testing the ports as IO.
