Voltage to MIDI converter with AVR

Guest
The following link (http://tomscarff.tripod.com/cv2midi/cv2midi.htm) shows a
voltage to MIDI convertion board based on a PIC.

I wonder if there is a similar work for AVR (8535 etc) ?
Does BACOMAVR support MIDI functionality?
Is there any AVR compiler with MIDI functions?
 
If O remember well, MIDI is UART with TTL levels and with not standard
speed. So I think that you hav't any problem. Also you can find +5v at
MIDI port.

And don't forgot that joystick have 4 ADC channels. Maybe this was
more simply.

You don't and it ain't. MIDI is a 5mA current loop @31.25kHz

You don't find 5V either, although you might on a PC game port ;-)

Sorry. You right. But at all it's standard UART. And you can use
standard AVR UART.

Yes.
