I have the following task. I need to transfer 1kB of binary data from the TMS320F28388D processor to the ESP32 device. On the DSP side, I will use the FIFO mode, i.e. 16 bytes in the single frame 1Mb/s. I would like them to be received on the ESP32 side not in a loop function, but by DMA mechanisms which works in the background (it means that HTTP, FTP, mail, OTA is active). Can I count on tips?

Hi.
I don’t think there are any examples of UART in DMA using Arduino IDE.
I think for that you need to use espressiff IDF.
