Continious conversion for Kinetis K ADC using AN4590

sohalpatel — Fri, 28 Jun 2013 11:22:44 GMT

Hi,

I am working on Kinetis (K10) for the last year, and the question is regarding the use of DMA for ADC as mentioned in AN4590. Can I use the ADC in continuous conversion mode and not use the PDB trigger source? My intention is to make the conversion as fast as possible.

Regards

Sohal

Hi, Sohalpatel

PDB is just a trigger signal, ADC itself can run in continuous mode. So you can use ADC without PDB trigger.

Hope my reply can help you.

Best Regards

Paul

Hello Zhe Tian,

I am glad you can give me some helpful ideas here. I wish to use both ADC with their differential inputs in a sequence, so i would like to have a trigger mechanism which could go and change the next ADC index. This is similar to the operation demonstrated in the Application Note.
