Is anyone currently working on support for the Model 100 in QMK? If not, I’ll give it a go. I’d appreciate any hints or gotchas.

I asked about this in the discord channel and @algernon mentioned he could help anyone interested in doing this to the best of his abilities

To be best of my knowledge, noone is working on Model 100 support in QMK. I expect it will be harder to port than the Model01, because in that case, QMK already had plenty of keyboards that used the same kind of MCU (ATmega32U4). In case of the Model 100, the MCU is from the GD32F30x family, which n…

Presumably I can base the work on the support that was added for the Proton-C as the STM32 appears fairly similar apart from the obvious differences in memory and clock speed.

Happy to help with this any way I can. I am pretty good with QMK but not to the level of MCU configuration… but I can alpha test and help with the board config itself. I have 2 sets of 100’s so I’m not scared of losing one in the name of progress :slight_smile: (but would prefer not to of course). …

[image] blitzbits: so I’m not scared of losing one in the name of progress Even if you flash a completely different firmware, even if it crashes on boot and doesn’t even enumerate, it is very hard to brick a Model 100. As long as you do not overwrite the bootloader (which requires specialized…

Thanks for the offers of help, I’ll let you know how I’m getting on. It looks like the GD32F30x family is supported in chibios which is a good start. What I could do with now is the actual MCU model, pinouts and matrix and also how this differs from the Model 01.

Looks like a GD32F303CG? Here is a pic if this helps: [IMG_0135] GD32F303CGT6

I’m see that the mlego/m65 rev 2 uses the GD32F303CCT6 mcu.

The bit I’m missing at the moment is the pinouts and matrix, perhaps @algernon or @jesse could point me in the right direction. Or, maybe I’m just too lazy to trawl the Kaleidoscope code.

Thanks, it looks like they mock this as a STM32F103 which would be a good start, I assume the registers are the same but the memory layout may be a little different.
