Help help ! :-/
I'have done lot of tests, but I'm definitely unable to send (and correctly receive) midi messages, using :
- wire : the tx pin, the 5v + 220 ohm Resistor, ground
- the serial baud rate 31250
When I'm checking the com port, I'm able to read note on messages.
My prg is basic and for me, it works : (same from here http://arduino.cc/en/Tutorial/Midi
I have checked and checked the wiring, It seems to be right.
I was wondering if on usb mode, the seeeduino wasn't able to set the baud rate to 31500. Then I used external power. Doesn't change anything.
I've checked different options, the midi signal isn't received / or recognized by :
- my soundcard
- my synthesisers
- my pedal board
To complete my tests, i've tried to send midi messages via xbee (at 31500) and wiring xbee to midi port as here without the 7404N componenthttp://www.ladyada.net/images/midibee/midibeebb.png
Idem : I'm receiving what seems to be midi messages but they are not seen on my hardware !!
I'm very disappointed and have no more idea what to test !!!!! :'(
Help would be much appreciated !
