General • Re: DMA in ring mode running continuously

I found a way to avoid using the CPU but still I need two DMAs.
This passage in the datasheet had the solution in it:

If the channel is triggered multiple times without intervening writes to TRANS_COUNT, it performs the same number of transfers each time.

You just need to chain two DMAs and when triggered they will restart the same transfer, so no CPU needed.
