Resolved! Don't see DAC output for SINE wave with DMA

Hello,I followed a tutorial on how to generate a SINE wave using DAC and DMA that was really good. Logically it makes sense, you set up the DAC, set it to be triggered by a timer, then set up the DMA channel, set it to circular, and set it to use a t...

Resolved! STM32F7 DACs enabling inconsistently upon powerup

Using STM32F765VG6TR, every time I power on the MCU, the two DACs are supposed to be set to constant output voltages of 2.4V and 0.8V. This happens inconsistently - sometimes it works, about 50/50 success rate. A few notes:If it isn't working, an MCU...

What fastest way to change the size of the DMA addressed by a peripheral. In particular the DAC? Stopping and starting the DAC using HAL_DAC_Stop_DMA and HAL_DAC_Start_DMA with a new Data Length takes up a lot of cycles if I use the CubeMX functions. I

I tried DMA_SetConfig after __HAL_DMA_DISABLE and clearly it is not enough.Incidentally my intention is not change the size of the DMA allocated area - rather the size of this region accessed by a peripheral

Resolved! STM32G474 DAC with DMA doesnt work

I have trying DAC with DMA from STM32G474 eval board. I can see the values being updated to the DOR register and the DAC EN is set to 1. However, the output of the DAC is stuck at 0.I have attached the cubeide settings.
