rask's BananaSplit60

Notes

Layers

Base layer is a regular HHKBish ANSI layer. Toggling the alternate base layer (Fn3) makes it simpler to play games with the left space being set to be an actual Space.

Layer 1 (Fn1) contains usual 60% functionalities such as the F-row, while Layer 2 (Fn2) contains media controls.

The final layer (Fn4) is a special layer that acts as a lock layer, meaning the keyboard is locked while the layer is active. This firmware assumes a lock switch (read below).

Lock switches

1.25u between the split space halves and the 1u key right left of LeftArrow are to be operated with a lock switch. If you don't have lock switches you should swap the MO() calls with TG() calls to make the layer toggles work with regular non/locking switches.

How to make and flash

(These instructions are for Linux-based operating systems with dfu-programmer available.)

cd into the bananasplit keyboard's directory and run

make rask

which should result in a file called bananasplit_rask.hex appearing in your QMK root directory.

Now plug in your BananaSplit60 keyboard via USB. Verify with lsusb that it appears. At least my PCB did not have anything preflashed so you should see atmega32u4 or similar in the lsusb output.

Now you can flash the firmware by

$ sudo dfu-programmer atmega32u4 erase
$ cd /qmk_firmware/root/directory
$ sudo dfu-programmer atmega32u4 flash bananasplit_rask.hex

If you happen to have some other atmega32u4 based device I suggest you plug it out before flashing your BS60 just to prevent accidentally flashing your old device.
