|
|
* Lightweight macro implementation of Arduino style pin numbering
|
|
* for AVR microprocessors. Because only thing I want to use from
|
|
* Arduino libraries is the pin numbering scheme.
|
|
*
|
|
* This file taken 99% from the excellent ArduinoLite project by
|
|
* Shikai Chen <csk@live.com>. Some minor changes to suite my personal
|
|
* coding taste.
