Hi, I've been working on my own control too. I use atxmega32a4u. The footprint allows it to fit under one cherry switch. Here's some of the prototypes: .

Hi, I've been working on a modular split keyboard firmware and controller. I've posted this elsewhere, but I thought it would be good to post it here as well.

The idea is you can have split keyboards connected together via I2C, and when you disconnect them you can use them as
wireless keyboards ...

Nice! Getting the board into bootloader mode is a bit of a pain. HzFaq had the ingenious idea of hooking the two pins on to a Matias switch to make it more accessible. Highly recommended!

You can get the promicro into bootloader mode through software using this function:

How I wish I've heard of that earlier! How does it compare in terms of refresh rate? And if there is a difference, is it obvious?



The serial it uses runs at about 40k baud, and for each scan of the matrix it transmits 48 bits (4 bytes for key matrix, 1 byte for LED state, 1 byte error check ...

Looks similar to my old build http://i.imgur.com/VQKW7nA.jpg .

You might be interested to check out the firmware I used for my build. You connect the halves with only 3 or 4 wires (so you can use TRS, TRRS or USB) and you can connect the USB connect to either half or use them indepently. Also, you ...
