V1.0.0 and QMK

[methoxid]

Hi Megamind!

Excellent work, purchased 2 stemcell v1.0.0 from 42keebs with the intent of running QMK on Sofle RGB V3.2 (non - standard).

I know about some limitations and that QMK only supports V2x of stemcell, but before I order replacement or opt in for rpi pico, is there maybe some of your notes from past on trying to run QMK on stemcell v1.0.0 ?

For me it is a question of invested time; if I can solve v1.0.0 with custom QMK build on a split keyboard with RGB faster than ordering replacement sets, I am in.
I am able to compile, flash and run a code, OLED works, keys work, but split over bitbang 1 wire does not, neither are the keys in the correct columns, which I see more of a QMK detail configuration before compiling, which I did not invest time into yet.

• Is it doable in short time?
• if so, any notes / step by step how to tutorial from your past tests perhaps?

Any help is much appreciated.

BR from Slovakia.

hi @methoxid - I think you can use this diagram to remap QMK pin definitions to suit your needs:

I had made some changes in this file to get it working, but I since reverted. It was a couple of years ago:
