/* keybrd_PCA9655E.ino
keyboard layout is same as top-left keys of DH matrices:

  Controller                I/O expander
| Left  | **0** | **1** | | Right | **2** | **3** |
|:-----:|-------|-------| |:-----:|-------|-------|
| **1** |   q   |   w   | | **1** |   u   |   i   |
| **0** |   [   |   b   | | **0** |   h   |   y   |

PCA9655E pin assignments are compatible with this sketch and keybrd_DH.ino
