I am using STM32F411 and SDK v1.27.1I am trying to trigger an DMA xfer with an external signal source using the TIMER1 External Trigger, without the need to execute any interrupts in the CPU to utilize the CPU time, as I have two signals one every 2m...

What is the DMA peripheral flow control and when to use it? and can be used in UART Tx?

Dma not working when triggered from timer trigger from external source start a DMA transfer on UART or SPI peripheral on STM32F411?
