AVR-MIDI - an USB MIDI-class compliant device

This is an inexpensive DIY MIDI controller device for USB. It consists of a simple AVR ATMega16 with driver software from Objective Development (see).

This USB MIDI is build upon an AVR ATMega16, powered from USB through 2 diodes (3.5 volts). Up to eight potentiometers (AVCC/AGND) are connected to the analog inputs (PORTA) which are converted to a range from 0x00..0x7F to create midi controls (CC).
