Tutorial 3b - autoShift
|
|
=======================
|
|
Some multi-layer keyboards have a symbols layer that writes symbols without using the shift key:
|
|
|
|
~ ! @ # $ % ^ & * () _ {} | < > : ?
|
|
|
|
The keybrd library does this by automatically sending a MODIFIERKEY_SHIFT scancode.
|
|
|
|
Two keybrd classes use AutoShift:
|
|
* Code_ScS
|
|
* Code_ScNS
|
|
|
|
The [keybrd_3b_autoShift.ino](keybrd_3b_autoShift/keybrd_3b_autoShift.ino) sketch explains the AutoShift feature.
|
|
It will run on the basic breadboard keyboard described in [tutorial_1_breadboard_keyboard.md](tutorial_1_breadboard_keyboard.md).
|
|
After reading the sketch you too will be able to automatically shifted characters.
