DAC1CON0 = 0b1010_0000 ; VDD reference. dac_set(MIN_DAC_VALUE) ; Output at minimum end procedure ; Write the given value to the 10-bit DAC. procedure dac_set(word in value) is DAC1REF = value DACLD_DAC1LD = TRUE while DACLD_DAC1LD loop ; Wait for DAC to complete transfer. end loop end procedure This was a very fruitful project for JAL since I extracted two JAL libraries from it, one to control a digital potentiometer and one to write data into HEF (this PIC does not have EEPROM but HEF instead) 😊 Hope this helps.

I'm trying to get the 10-bit DAC of the PIC16F1778 working and am not being successful. Has anyone used this, or similar? I'm scoping the output pin and getting nothing. Below is my code. Any push in the right direction is appreciated.
