I’ll look into putting some of this code on Github.

I don’t have a dependency tree, as such, other than my own code since I use stuff raw from the nrf5 sdk. The sdk source files which I’m using do need to be put into the build list but that’s moderately straightforward once you realize that missing linker references mean it’s looking for you to add yet another c source file from the sdk.

I have the entire nrf5 sdk as a Visual Studio Code project under git control so it’s easy to global search for stuff and to keep track of personal changes to the sdk such as adding support for the Xenon, or Nordic upgrades.

I did upgrade the CMSIS app so I can load an example sdk_config.h file and trivially tell what options they’ve set/enabled.

The gcc compiler that comes with the sdk is adequate although I think I use a newer one.
