Were to send patches & Looking for a example for ADC and DFSDM for the stm32f4
I still playing a bit around with Zephyr OS.
I manged so far to setup the UART1 using PA10 & PA15. This config is not included. I can submit a patch. Who is maintaining the stm32 dts?
Now I want to go one step further. I would like to use the ADC and the DFSDM module of the stm32f4. I was checking the sample section. I only found the "grove_temperature" as an ADC sample. But for me it still remains unclear how to do ADC in Zephyr OS from the scratch.
Maybe someone can explain it to me at an example:
My "simple" problem is to read the PC1(ADC Channel 11), PC3(ADC Channel 13) and VRefInt. I created my own board. I would like to know all the necessary steps to finally read in my main.c a value from the ADC :D
Think to solve this I need to add some lines at
The stm32f4 MCU contains a DFSDM interface. I like to use it to read microphone data. Are there people who tried to do this in zephyr? What were the steps? Is there a DFSDM driver?

I've not heard about DFSM support so far, but support would be welcomed indeed.
About ADC, I advise to have a look to adc drivers implemented so far /drivers/adc/.
You could rely on STM32Cube HAL to help you in implementing the driver.
For new pin configuration , you should know that pinctrl is not used from dts yet,
but you can submit a patch and we can have a look.
