MHVLib - an efficiency oriented library for AVR microcontrollers

Whats Implemented
* Digital I/O
* Timers
* Serial (both busy-waiting and asynchronous)
* External Interrupts
* Servo control
* Analogue to digital
* Hardware PWM
* Gamma correction - calculate on the fly, or lookup tables (recommended)
* Fast synchronous serial shifter
* Software H Bridge for driving naked transistors (with PWM support)
* Realtime Clock & event triggering
* Debouncing (detect button presses, as well as held buttons)
* Software PWM Matrix (for passive LED matrices)
* HT1632 based LED matrix displays such as the Sure Electronics DE-DP105 (search for 0832 led matrix on Ebay)
* HD44780 & compatible LCD character displays
