This sketch:
2016-07-18 02:03:03 +00:00
is firmware for a simple 2-layer keyboard
2016-05-09 14:05:08 +00:00
runs on the first two rows and columns of a breadboard keyboard
| Layout | **0** | **1** |
2016-09-20 01:46:03 +00:00
|:------:|:-----:|:-----:|
| **0** | a - | b = |
| **1** | Alpha | Sym |
Pressing the "Alpha" layer key locks the Alpha layer.
Letters 'a' 'b' are on the Alpha layer.
Pressing the "Sym" layer key locks the Sym layer.
Symbols '-' '=' are on the Sym layer.
