Arduino for STM32

Update:
I tried running the DAC with the STM32CubeIDE. The DAC_DataOut Registers had the correct value without any voltage at the output.
Got really frustradet. Had a break and an idea.

The Nucleo I used was used by a colleage before who desoldered the juper for the reference voltage and Vref was ...

Thanks for that hint. I created an buildopt.h and added the -DHAL_DAC_MODULE_ENABLED line.

Sadly I don't get any output from the DAC

I’m running into issues with the DACs on my NUCLEO-G071RB.
According to the STM32Duino API documentation https://github.com/stm32duino/wiki/wiki/API#analog an analogWrite command on Pins PA4 and PA5 (DAC outputs) should result in an analog voltage at the pin driven by the internal DAC.

I tried the ...

Hi Folks,

after countless projects with Arduino boards I need more capable controllers by means of processing power and IO. Thought it would be a good Idea to stay with the Arduino IDE but guess what, it doesn’t work out that easily. That’s why I’m here.
