|
This sketch:
|
|
is a simple 2-layer keyboard with AutoShift
|
|
runs on the first two rows and columns of a breadboard keyboard
|
|
|
|
| Layout | **0** | **1** |
|
|
|:------:|-------|-------|
|
|
| **0** | a ! | b @ |
|
|
| **1** | fn | shift |
|
|
|
|
The layered keys in row 0 have two layers; one character for each layer.
|
|
Letters 'a' and 'b' are on the normal layer. Symbols '!' and '@' are one the fn layer.
|
|
Holding the fn key down makes it the active layer. Releasing the fn key restores the normal layer.

HOW SHIFT WORKS
|
|
When a shift key is pressed, a standard keyboard driver will temporarily modify the action of other scancodes.
|
|
KEY_1 writes '1'
|
|
MODIFIERKEY_LEFT_SHIFT + KEY_1 writes '!'
|
|
|
|
KEY_2 writes '2'
|
|
MODIFIERKEY_LEFT_SHIFT + KEY_2 writes '@'
|
|
|
|
HOW AUTOSHIFT WORKS
|
|
Code_ScS takes care of the MODIFIERKEY_LEFT_SHIFT automatically
|
|
When the user presses '!' or '@' on the fn layer:
|
|
Code_AutoShift checks the position of each shift key
|
|
Code_ScS sends MODIFIERKEY_LEFT_SHIFT scancode if needed
|
|
Code_ScS sends its scancode
