  • For me, this is the most valuable firmware update to date. Especially the possibility to easily start multiple files in sync opens up a world of possibilities, making the WAV trigger perfect to do live multitrack mixing and mastering the same way commercially available applications, -costing many times more- would. I’ve found the fade-commands very useful, too. They work as advertised and are hyper-fast.

    I haven’t tested the Arduino library as I’ve been testing with a terminal program on my desktop, but for what I can see so far, it really become very easy to implement live music mixing capabilities in any Arduino project.

    Love it! Thanks!

  • I guess it would depend on which connector you reversed the polarity. Did you mistakenly did so?

  • While you are at it, could you consider adding the ‘start group’ command? If it’s not too much work of course. With the increased serial buffer it works as expected but a ‘start group’ command would be a more elegant solution :)

  • The bootloader is custom developed, so only boards directly purchased at sparkfun have it installed.

  • It is. See one comment below.

  • The prolific issue (few posts down) seems to be no more. After spending 2 hours trying to reinstall an old computer with an actual serial port, I decided to try one more time in the same configuration that I tried before, given that I haven’t been working on the project for over a week. BAM, first try it worked. I figured it would be a lucky accident, given that it had worked once before (I believe for the upgrade to 0.57), and then never again to 0.59 until now. When I came back to the forum to report this, I noticed that 0.61 had been released so I figured I could try it again. Flawlessly. No idea what’s different now, it’s the same USB port, same operating system and same prolific driver.

    Thank you so much for the improved serial buffer, sending 4 commands back to back works like a charm now. Thanks!

  • Ok, that should be good. The next step would be to see if there’s 3.3V on the MIC5323. It takes the 5V from the LM1117 and generates a 3.3V source. It’s the chip to the right of the regulator that you just measured, but a lot smaller. 3 pins on the upper side and 2 on the bottom side. Measure between the right pin on the bottom side and the SDcard socket.

  • Ok. If you have a multimeter, check if there is 5V on the ‘output’ pin of the LM1117 regulator (right next to the barrel connector, with 3 pins on one side and 1 on the other.) Measure between the single pad and the metal SDcard socket.

  • Do you see the red LED? Make sure that your barrel connector has the 12v on its center pin, too.

  • I’d try first of all try to make the board work without using serial communication to check if your power supply works. The board should have a red LED that flashes every second or so, even if you have a problem with the files or sdcard. Like suggested, you need to put a drop of solder on the jumper to make it work over the ftdi header.

No public wish lists :(
