Hi everyone, Im a new member and this my first post, but I have spent many hours pouring though old posts as a guest. I cant seem to find a real solution to my current problem and I'm hoping someone can help me out. I have been trying the venerable MIDI-IN: code + schematics (Sorry, Link in next post) without much luck. The optoisolator circuit is working fine. I get about 5v at opto pin 5 with a few tenth's of a volt variation corresponding to keystrokes. Also, when the RX is disconnected , a LED connected between +5v and pin5 flickers when keys are pressed. I have removed the resistor from pin 6 to ground. The Led will not light with it in and many reported that it was not necessary. I have tried nearly all of the proven sketches, (especially the simplest ones with one led to signal midi data recieved) in the midi in thread and tried different baud rates, but so far no data seems to make it to the arduino. There were a few post by others who seemed liked they were having the same problem, but no real solution was posted. Some said that it just worked after rebuilding the whole thing, but unfortunately that didnt work for me.
Ive checked for cold soldered joints on the arduino(diecimila), thats not it. I tried different keyboards, I was using a microkorg but then tried my sci prophet 600, no luck.
Anyone have this problem or have any ideas whats going on? Im pretty good with hardware, but software is my achillies heel and Im not sure what to try. Thanks in advance. Charlie
