Using UART with DMA on ESP32-s3

Postby Serdar » Thu Oct 20, 2022 2:41 pm

Hi, i want to use Transmit/Receive operations of the UART with DMA.

But I couldn't find any resource on this subject other than this PDF.
https://www.espressif.com/sites/default ... ual_en.pdf

Here are my questions:
1-) Is there a better option for DMA than register-level programming?
2-) Is there a example code UART with DMA for ESP32-s3
3-)Is there an ESP-IDF API's that uses the DMA feature?


Thank you for your time, and have a nice day!

I would second this request:
We also need uart dma working on esp32-s3.
