Hello

How do I change the Vref on the SAR ADC during run time?  I'm using single ended configuration with VSS at negative Vinput.

thank you

Hi Shawn,

This can be done. Please check the following KBA. Also make sure that you are giving enough delay between changing Vref to get accurate results.

Thank you

This was the solution.

Where can I find a list of the registers within the PSOC 4200?

Hi Shawn,

Device Registers TRM has this information will have all the information about the registers. See PSoC 4200 Registers TRM for more details.

Best Regards.
