Hi Peter, nice to see you’ve moved from beta to RC. The version has really come a long way!
In the meantime, I’ve picked up a PicoCalc to test.
I’m surprised to find that, unfortunately, you can’t control the screen brightness using the BACKLIGHT command, even though it works with the keyboard shortcut. It would be great to control the brightness via the program.
Also, unfortunately, the RTC on the STM32 (BIOS 1.6) isn’t being read, or can’t be written to either?!

OPTION SYSTEM I2C GP6,GP7, SLOW
Is this really I2C or is it I2C2? Something is responding at address 1F...
Otherwise, I can't read anything on the I2C bus either;
is that probably not possible because it's reserved for the system? Is this because of reading the keyboard?
Could you please explain some background information on this? Thanks.
