Some QMK support for modded two-handed maltron keyboards does exist already. #1

Hi,

I recently was faced with a similar problem and hacked my two-handed Maltron keyboard to work with QMK:

https://github.com/dvdkhlng/qmk_firmware_dqz11n1g/tree/master/keyboards/handwired/dqz11n1g

Upstream QMK did accept a pull request with my firmware changes, so this specific keyboard is now also listed in the online QMK keyboard configurator:

https://config.qmk.fm/#/handwired/dqz11n1g/LAYOUT

It looks like your right-handed maltron's controller also uses a 17x2 DIL connector, so there might be some chance to come up with a controller board that supports both Maltrons.

I did not succeed in sourcing black-pill controllers so had to base my work on an Arduino pro-micro controller.

cheers,

David

In theory it should be possible to make a generic board that will work across all the current PCD Maltron keyboards. It looks like all but one pin is the same. I'd still opt to use the MCP IO Expanders again as these can be reconfigured in software on the fly leaving more versatility. Thanks for sharing your work, hopefully this will be useful to others modifying these Maltron keyboards.
