Hi,

there is SDK example for UART using DMA. You can use it as a reference:

Hope it helps.

These examples have been seen, but not very well illustrated

Here are some bad instructions:


1.The DMA example does not give the DMA size setting, I do not know the size of the send and receive

2. Can the serial interrupt DMA receive only one byte?

-------------------------

I want a DMA example like this
1. The size of the serial port receiving and sending DMA can be configured
2. Use the serial port idle interrupt to save the received data at one time when it is idle

-------------------------

Finally, I also want an example of a serial fifo. Can you provide it?

Best wishes to you
