STM32F303CBT6 DAC and PA4/PA5

I read a lot about it for other STM32 MCUs but can't find any confirmation that it’s not possible to use PA4 and PA5 as GPIO output and DAC1 channel 1 and channel 2 internally for STM32F303CBT6. There's a hint in the errata of another STM32F303* usin...

Resolved! STM32F091RC DAC PINA4 PINA5 not working

I have been following mastering stm32 book for a while now and checking out the tutorials from the st channel.I was following the dac tutorial and I had a problem with outputting analog signals in pin A4.I use eclipse IDE and i am imporing cube-mx fi...

STM32G431KB DAC DMA not working

Trying to get a basic sample DAC1 with DMA, triggered by TIM2 working. This should be trivial, works fine on SMT32F3. I'm using a Nucleo-32 SMT32G431.Using Cube IDE. The only non IDE-generated code in main is: /* USER CODE BEGIN 2 */   static uint...

Resolved! L431 Stops working after enabling ADC

Hello all,I recently ran into this problem where the MCU would instantly stop working after enabling the DAC. The behavior is that from the debug view of STM32IDE the program is still running, but all variable values are reset to 0, and once the prog...

GPIO connection on MCU

Hello,I'm relatively new to PCB designing and I've already learned a lot of things, but I'm still not sure about connecting 2 components through GPIO pins. I have IIS2MDC magnetometer and I would like to connect INT/DRDY pin to STM32H747AI. Let's say...

Resolved! DMA to DAC transfer in normal mode too slow

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...


L431 stops working after enabling DAC

I am trying to use the onboard DAC to generate a sine signal. The program runs without any problem on the Nucleo L432KC board but it would not work on our PCB with L431. As soon as the DAC is enabled with LL_DAC_Enable(DAC1, LL_DAC_CHANNEL_1); the pr...
