Some multi-layer keyboards have a symbols layer that writes symbols without using the shift key:
~ ! @ # $ % ^ & * () _ {} | < > : ?
The keybrd AutoShift class automatically sends a MODIFIERKEY_SHIFT scancode as needed. Two keybrd classes use AutoShift:
- Code_ScS
- Code_ScNS
The keybrd_3f_autoShift.ino sketch explains the AutoShift feature. It will run on the basic breadboard keyboard described in tutorial_1_breadboard_keyboard.md. After reading the sketch you too will be able to automatically shift characters.
- Modify the keybrd_3f_autoShift sketch to make a 3-layer keyboard with a default layer and two Code_LayerHold objects.
| Layout | 0 | 1 |
|---|---|---|
| 0 | a ! 1 | b @ 2 |
| 1 | sym | num |
- Modify the keybrd_3f_autoShift sketch to write 1 and 2, regardless of if shift is held down or not (hint: use Code_ScNS).
| Layout | 0 | 1 |
|---|---|---|
| 0 | a 1 | b 2 |
| 1 | fn | shift |
