Indeed! Thanks

Sorry, better to let someone more familiar comment, the MBED bit threw me, but looking at the board it might have some sort of drag and drop MBED mass storage controller type programming facility.


Thank you. I think you pointed me in the right direction... there should be some drag&drop feature ...

Actually, no. I am programming the board with Arduino IDE, but I cannot get rid of that driver: if I uninstall it keeps coming back as soon as I replug the board. Is there maybe a good driver to replace it?!

I have a silly but annoying :evil: issue with my L4R5ZI. Every time I burn a new sketch on it, it starts rebooting every ~1 second until I unplug and replubg the USB. Then everything is fine.

The reboot cycle seems to correlate with the disappearance and reappearance of the USB drive associated the ...

Hi everyone,

I need to run the DAC with DMA on the Arduino IDE. I have an STM32L4R5ZI and a Cube IDE project that works fine so I tried to redo the same things on Arduino IDE. I understand STM32duino does not support DAC+DMA (?!) and to make it work I had to push things a bit (see code).

So ...
