12F1572 DAC problems

[stivio]

Hello all,

I am trying to get something from the DAC of the 12F1572, but nothing works.

Now, I am trying to get only DAC function but still dont work.
The output is connected to a multimeter, not loaded.

Tnak you for your help!

the code:

[code]

#include <12F1572.h>
#fuses NOWDT,NOMCLR,NOPROTECT,NOLVP,INTRC_IO
#use delay (internal=8MHz)

void main()
{
setup_oscillator( OSC_8MHZ );

OUTPUT_A(0b00000000);

setup_vref (VREF_ON | VREF_ADC_OFF | VREF_COMP_DAC_4V096 | TEMPERATURE_INDICATOR_DISABLED);

setup_dac(DAC_OUTPUT | DAC_FVR);



while(TRUE)
{
dac_write (20);

delay_ms(5);

}

}
[/code]

The original problem solved:

Even the PICKIT3 is loading the output, so after removing connection, I get voltage from the DAC.

But some intresting news...

In case, when the DAC_FVR selected in setup, the register value is (A2) 10100010.
In case of DAC_VDD the output is 10100000.

according the datasheet it should be 10101000 and 10100000.

(my curiosity... I just checked... In case of DAC_VREF 10100001 ->it should be 10100100)

The wrong 2 bits are modified in the register, so needed to change them in the header files.
