  • Any chance I could emulate a HID keyboard on the USB interface?

  • Would love an open-source reprogrammable version of this with bluetooth and 5 UI buttons usual Up, Down, Left, Right, OK in the middle type deal....

  • I'm trying to port your SparkFun LED library over to i2cDriver from Arduino/Wire.h and come up with a generic library solution I can use for most of your libraries... But I'm having a crazy trouble with compilation of the borrowed and modified arduino libs which I'm yoinking progmem out of....


  • Can the D-/D+ pins be passed on to another board of yours to end up with serial? I bought one of the CH boards but despite passing a loopback wire test, it is unable to communicate with my supposedly 3.3V device I had no trouble talking to an RPI with. I'm looking for alternatives and figured while I'm at it, I might as well source power.

  • It's actually unusable even on an empty i2cdriver bus with only 3 of these connected and doing nothing yet.

  • I second this. I've seen this same thing. I changed my whole lineup just to work around it thinking it was the RPI's crappy bus, only to find it's the perfect storm for both.

  • Judging from the firmware, I can plug one in, change its address in software once and that will be written in firmware. The other I can just jumper with solder.

  • I was able to get it to work by cribbing off of your library with some other RPI i2c code i found, thanks! Now I'm working to see if I can hook more than 2 of these to one device.

  • Would love to see some Raspberry Pi code for this...
