This is a demo that I have made for ROENDI using the onboard DAC, buffer, timer and QPSI flash in memory mapped mode. It is fun little project. I will be sharing the code soon on the GitHub repo.

I was struggling at first to configure everything. As you can see there were a lot of moving parts.I have seen the Application notes, some example from STM32l476GR-NUCLEO, but nothing was running properly.

At last I found a blog of a Japanese dude  (NuTubeチャンネル). I could not figure out the comments, but the code was good. C code is international language and breaks borders. Then I  could piece together the puzzle.

The code example for RoEnDi:
