Hi to all,
I am encountering a problem, concerning the DAC of the stm32L476. I only want to use the DAC with a constant value but with DMA, so that I can use the CPU during that operation. Without DMA the DAC works as desired.
Now my question is: How can I start the DAC with DMA without a Timer? The function we used is:
and since we want to use a software trigger, we added
afterwards, to start the DAC-conversion. Nevertheless, we cannot measure any voltage. In CubeMX we configured the DAC with a Software trigger and the DMA as Normal and Half Word.
Can anyone help us out?
We just don't know what else we can do.
Thank you a lot in advance,
