+avrcounter - Incremental encoder counter on AVR microcontroller.
+Microcontrolers often have counter inputs, but they do not have any dedicated
+inputs for incremental encoders which are therefore tendious to decode without
+any external logic.
+The avrcounter implements this decoder in an AVR which must be dedicated to
+this task. The number of encoders which can be decoded this way depends on the
+encoders maximum frequency. More encoders means more instruction to decode,
+and lower maximum frequency.
