Triggering the DAC DMA with HRTIM

Hello,I am trying to trigger the DAC1 DMA off of the HRTIM Master channel using the hrtim_dac_trg signals on an STM32G474, but I am not getting any output on my DAC pin. The timer does seem to be running (I can see MCNTR incrementing in the debugger)...

STM32H7 TIM12 TRGO DAC DMA syncronization

Hello,I am trying to generate a pulse-triggered waveform continuously by using DAC and DMA in STM32H735RGV6. To do this, I have opened DAC OUT1 with the following configuration.After that, I set up the TIM12 with the following configuration and expec...


4 DACs, 4 audio rate sawtooth waves with SMT32G4

Hello,I am looking to develop with the STM32 microcontrollers for the first time and was hoping to get some help. I need to create a device capable of outputting 3 separate sawtooth waves that are individually controllable to synthesize audio based o...

Resolved! ADC sampling rate checked by callback

Hello,I am using a NUCLEO-H743ZI2.I read the reference manual RM0433 Rev8.I also read a bunch of topics in the forum but didn't find what I wanted. I am trying to check my ADC sampling rate by looking at the timestamp at my half full/full callback fr...
