Hello,

I am very new to PSoC and for my senior project, I am trying to implement something. For now, I am playing around to try to learn how to use the DACs and VDACs. I am implementing the following schematic.

I am just trying to read the output of the VDAC8_1 and output it on the VDAC8_2 so I can read it with a multimeter (Simple right?). My problem is, how do I do this? Like I said, I am very new and this has not been working.

Thanks

Hey Bob,

I think I figure it out, However, whenever I sample it and convert it back to analog, the analog voltage seems to be about half of the input VDAC vaue.

Seems that it caused by SAR ADC Vref selection?
