Hi,I'm using STM32G431RB on the NUCLEO-G431RB developement board.I want to generate a signal from an array each time an external trigger is received.The signal is sampled with the TIMER6 trigger, which is rised every 1us. (MCU clock is 170MHz, TIMER6...

DMA in continuous mode, timer6 start when trigger comes and timer6 stop when DMA DAC transfer completed works fine!Thank you!

I tried to continuously call HAL_DAC_Start_DMA in the while loop followed by a HAL_GPIO_TogglePin and the result is:

Thank you MasterT for your answer.By setting the DMA in circular mode I don't obtain the wanted behaviour. I mean: I don't want to generate continuously the waveform, I want to generate the signal only when the external trigger rises. The signal dura...
