finish my re-write of my MIDI lights firmware. It's the line that modifies the MIDI library so that it passes any incoming bytes to the THRU port.<br><br>In my old program, I just did a Serial.read follower by a Serial.print, as follows:<br><br>void loop () {<br> if (Serial.available() > 0) {<br> newbyte = Serial.read(); // read the incoming byte<br> Serial.print(newbyte); // echo the incoming byte<br>...<br><br>I tried that again here, but with no luck. Then I looked at how they send data to the serial port for MIDI OUT in the library, and saw that they use a slightly different syntax: serial_.print (b, TYPE). So I tried adding that instead, as follows. I've included an extra snippet that shows how they're doing it, for context. My line is the one with the asterisks. I assumed that I could ignore the type argument, since I'm just passing the (int) variable c straight
thru. (I also tried it as INT and BYTE types):<br><br><br>// Try to read data at serial port & pass anything read to processing function<br>void Midi::poll(void)<br>{<br> int c;<br><br> // Just keep sucking data from serial port until it runs out, processing<br> // MIDI messages as we go<br> while((c = serial_.read()) != -1) {<br> recvByte(c);<br> serial_.print(c); // ***** pass MIDI data THRU *****<br> }<br>}<br><br><br>// Send Midi NOTE OFF message to a given channel, with note 0-127 and velocity 0-127<br>void Midi::sendNoteOff(unsigned int channel, unsigned int note, unsigned int velocity)<br>{<br> int status = STATUS_EVENT_NOTE_OFF | ((channel - 1) & 0x0f);<br> <span

Please let me know if you have any ideas. By the way, this MIDI library seems to work pretty well otherwise (with only one
light).</span></span><br><br>Thanks,<br>-Hans<br></div></div></div></div></div></div>_______________________________________________<br>dorkbotpdx-blabber mailing list<br><a rel="nofollow" ymailto="mailto:dorkbotpdx-blabber@dorkbot.org" target="_blank" href="mailto:dorkbotpdx-blabber@dorkbot.org">dorkbotpdx-blabber@dorkbot.org</a><br><span><a target="_blank" href="http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber">http://music.columbia.edu/mailman/listinfo/dorkbotpdx-blabber</a></span></div></span></blockquote></div><br></div></div></div></div></body></html>
