Re: RTC Calibration program
Does anyone know at what point the ppm display under Setup — Settings gets updated, after changing the rtccalib.cfg file? I've just edited my file, changing from -21 to -22, but the display is still showing -21ppm. I've double-checked the file content (on a PC), turned the DM42 off/on a few times: ...

Re: Dutch Lion
Here's my attempt at the Welsh flag, based on the SVG in Wikimedia Commons. In Inkscape, I changed the colour of the grass to 25% grey and the colour of the dragron to 50% grey, and exported to a PNG of 400x240. In The Gimp, I converted to 1-bit black and white in pattern mode, touched up some stray...

Re: BAT indicator stuck on
Also check the Vdd value on the DMCP Self Test Diagnostics page. I think it should be reasonably close to the battery potential in millivolts, except when powered by USB. In any case, it's more info for diagnosing the fault. I had noticed that Vdd was odd (1221) yesterday, so assumed it wasn't what...

Re: Naïve Analysis of TRNG
Does this use the STM32's hardware RNG (which is based on an analog circuit)?

Re: DM41X Beta Programme
Just got my Beta unit, wonderful, thanks very much. The BAT indicator is on, I take it that means I need to change the battery? hmm. Changed the battery, put in a fresh CR2032. BAT indicator still on. Tested old and new batteries on a tester: both show as full. Does this indicate a hardware issue w...

Re: Firmw update issue on Windows 10
Which firmware are you on at the moment? Is it recent enough to handle firmware updates using the FAT disk update method?

Re: Building a .pgm on Windows
It would require reimplementing the functionality of the shell scripts in C or something. An alternative may to build in an MSYS2 or Cygwin Bash shell environment.

Re: USB-host (USB-OTG)
The STM32 chip supports OTG. I don't think the DM42 is wired up to support it. Amongst other things, it would need a high speed crystal (4-48 MHz).
