Unless I’m completely wrong DAC is for outputting a 0-31 fraction of supply voltage (by default anyway). Is this correct? I don’t specifically need it for anything, however I’m writing a school report and it would be good to have a better understanding. Therefore I was trying to simply dim an...

What are the required basic commands to run a DAC output on a complainant such as an LED. Or is this even possible? I am using a 28x2 and cant figure out how to do this. I currently have the LED on pin a.3 which is not a PWM pin and am wondering if DAC does a similar thing to PWM in terms of...

Cheers for replies. After posting I played around with ADD CONFIG and FVR and managed to get the 1.024 vref working, values now range from about 80 to 120. I currently have a 470uF capacitor that helps a lot with fluctuations but still not perfect. Averaging seems to be the way to go. If I have...

Hi I have made a model elevator for a school project. Its running a 28x2 from a 5V USB power supply. I have connected the negative pin of my motor H-Bridge to a negative pin of the Picaxe and also to negative via a 1 ohm resistor in parallel with a capacitor, creating a potential divid sort of...
