PIC12F1572 using DAC output
So, I've tried on both the Curiosity LPC board and my own board, but all the time a programmer is connected, I get a poor output from the DAC (on RA0). It seems that the programmer drags the output down. Is there any way to make the programmer go properly high impedance, or do I need to add a manual switch to connect and disconnect the RA0 connection to the programmer - i.e. connect during programming, then disconnect afterwards? If I power up the board without the programmer connected, the output is fine, but it's inconvenient while developing, obviously.
Any ideas other than the switch?
