Use dma to read adc on RT1176

lfost · ‎10-10-2022

Looking for a sample project that uses dma to read the adc on RT1176

Hope you are doing well. Thanks a lot for reaching our technical support.

Regarding the code that you are asking, let me see if I can have one example project with the characteristics desired.

I would like to know how many channels from ADC and how many bits needed too, and for DMA, how many channels too, so I can search internally if we have some project like that, but I cannot assure you one example project, because our SDK does not support that example, but I will make sure to do my best for you.

Best Regards.

Hi Pablo thanks for helping. Our application calls for 10 single end adc channels to be sampled using dma access. Highest resolution possible maybe 10 bit. Not sure how many dma channels.

Hi @lfost

I appreciate your fast response.

Regarding your request, I would like to firstly suggest you a post that might be so helpful for you and your requirements. But this one is for LPC mcu's but I think it can give you an idea on how to do it for RT1176.

Please let me know if you need more assistance after checking it, or if you have some more questions.

Best Regards.
