@felmue Found it! Thanks!

I'm looking for the source code for the STM32F030F4P6 firmware on the M5Atom Joystick with M5AtomS3 K137. Can some one point me to it?
Thanks!

Thanks!

I want to use GPIO34 on the Core2 but I have not been able to make it work as a digital output.

The structural files from github don't seem to include the panels for the base26.
Would it be possible to obtain those?

I purchased a base26 for use with my Core2 however when powered by the DC barrel jack the core2 flashes the backlight and does not power up. I have two of these base226 units and neither appears to function with the Core2. I found no mention in the specification that indicates compatibility with Core2 or not. Should it work? Is there an alternate for Core2?

I have not used uiflow before but tried to get it running to test this. I was unable to get uiflow working on my windows 10 system.
Please provide an arduino C example.

I have several M5StickC-Plus's but I cannot seem to get the buzzer to work. The factory test has code in it to use the buzzer on button press but it does not seem to work. Can someone point me to code to make this buzzer work?
Thanks.
