DM 42 Source code updated

I love the ASCII large font they used in their /dm/*.cc files.

Interestingly, although this isn't a full source release, I have found nothing FreeRTOS-like as I take my brief read through the files (For example, the characteristic FreeRTOS naming style). I remember someone mentioning it, so now I'm curious about the unreleased part.

It seems that they didn't use the CMSIS library, didn't use the STM32 HAL or LL or SPI library. The licensing issue is not as severe as I imagined.
