Hi,

I wish to acquire data in continuous mode from Uart, without that the acquisition is completed every packet but after  all packets are sent. Thanks for every help. I attach my code. #dma-usart

That looks like a whole heap of fun.

I'll point out that Buf_rx[] doesn't allocate any buffer space behind it, and then you write to this non-existent space.
