At the suggestion of some helpful users on Discord, I've put the contents of the /sys disk up on GitHub:
https://github.com/JoeStrout/minimicro-sysdisk
So feel free to poke around, and if you want any changes, either submit a pull request or simply send me your suggestions!
I noticed some unit tests for /sys/lib/tsv.ms are failing, so I just send a pull request. Apologies if I did something wrong, never done one before 😅
/sys/lib/tsv.ms
Looks like you did it right. Thanks for the PR! 🙂
