    There still aren’t many MIDI 2.0 compliant devices to test with. The USB spec was released, so we may see Apple and Microsoft build it into future OS updates, which would help get things started.

    No Linux drivers, and google searches seem to indicate that Roland synths are "useless" in linux.
  3. Roland USB MIDI devices and T3.6 USB Host port

    There are a few manufacturers that still make USB MIDI devices that require device drivers to use on Windows or Mac OS. These devices do not work with the T3.6 host port. The simplest workaround is...

    Thanks KurtE, that worked! It seems that repeatedly disconnecting and reconnecting certain USB MIDI devices will cause the sketch to hang, but that may likely be something in my code. I'll report...
  5. T3.6: How to detect when a new USB device is connected to the host port/hub

    Does anyone have an example of how to detect when a new USB device (in this case MIDI) is connected to the host port of T3.6? It doesn't need to be immediate, but if there was a flag to test for new...

    Ok, upon further research it looks like the only option is to pre-program the flash memory and then solder it to the board. Not very practical, the least buydisplay could have done was put ICP...

    Reading the RA8875 datasheet, looks like the flash SPI interface supports dual and quad lines, potentially doubling or quadrupling the SPI speed. What I don’t see, is how to write data TO the flash...

    Thanks Morgan. Do you know if either library can successfully address (write/read) external flash memory on the buydisplay board? The RA8875 datasheet mentions how to read from it, but not how to...
