Resolved! NUCLEO-U575ZI DMA->DAC doesn't work (USEF)

Hello everybody! I have a sine-wave array, that I throw to the DAC, triggering it by TIM6. When the TIM6 interrupt routine is responsible for supplying samples - everything works fine, but when I try to use DMA nothing works. The DMA keeps spitting t...

STM32F746G Disco DAC_OUT1 & DAC_OUT2 access?

Posted on September 01, 2017 at 06:37Hi, I have an STM32F746G-DISCO board and I am running some DAC examples. I need physical access to PA4 (DAC_OUT1) and PA5 (DAC_OUT2) so I can display them both on the oscilloscope.  The DAC example says you can a...

DAC via opamp follower

Hi all,I am in the process of bringing up a prototype board with a STM32L4R7ZIT6 up. I'm using one DAC channel via the opamp. This is working all right, until I designate the default output of the DAC to another function e.g. dig output. The DAC is c...
