* Added KidBrazil custom keymap for CRKBD
-Custom Font
-Custom OLED output

* Added missing readme

* Oled Timeout Update for KidBrazil Keymap (#1)

* Setup Oled timeout based on simple timer

* Cleaned up comments and added timeout for LEDs

* Fixed some small errors

* Updated oled timout with matrix scan

* Updated oled timout with matrix scan

* Update withou eeprom

* Update timer code

* Use process user instead of keymap

* Added ifdef to protect oledtimer
