Tutorial 3f - autoShift

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 shifted characters.

Exercises

1. 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

2. 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
