Hi, I'm using STM32F767NGHXX for a project. It is mandatory for me to use USART3 and UART7. I want to use both uarts with DMA transmissions but this 2 uarts use the same DMA Streams. Other option could be use one with DMA and the other use normal UAR...

Other doubt, This swap in the DMA Channel is possible? Or it can be that the DMA system is not prepared to be changed?I mean, i have test that the DMA registers are being written correctly but it seems to be not possible to change.

Hello, Before I had to start using also UART7, USART3 was working with DMA in a properly way. As soon as i needed UART7 (already defined but not used until then), i had to change the .ioc to set the DMA to the UART7 as the main UART with the DMA in a...

Hi,I use both, Tx and Rx. The problem with the USART3_TX on Stream 4, is that this stream is also busy with another peripheral.The process I'm following is the next one:1) First at all i Init UART7 with DMA (the FLAG condition is set to 0 at beginnin...
