I just got a rainbowduino with the UsbART module. I didn’t find many information about how to run it, anyway looking at the manual and the demo video, I attached correctly the UsbART module to the board and it to the computer.
On the UsbART I switched 5V_VCC_3V3 pin on the 5V side.
Connecting the board, the red channel seems to be ok, but the others aren’t (I don’t see rainbow colors, but only reds at diagonal’s sides).
In addition, the board isn’t recognized by the arduino software - which works instead for the Arduino Diecimila.
I’m running on a 64bit Fedora Linux. I’m not sure if this is ok, but the only thing I’ve got is dmesg output, which is like this:
usb 2-5: new full speed USB device using ohci_hcd and address 23 usb 2-5: device descriptor read/64, error -62 usb 2-5: device descriptor read/64, error -62 usb 2-5: new full speed USB device using ohci_hcd and address 24 usb 2-5: device not accepting address 24, error -62 usb 2-5: new full speed USB device using ohci_hcd and address 25 usb 2-5: device not accepting address 25, error -62 hub 2-0:1.0: unable to enumerate USB device on port 5
Hoping nothing’s broken
P.S. I’m gonna try asap using the Arduino to communicate with the board, instead of programming it directly, but this remains an issue I’d like to solve anyway.
EDIT: Connecting the power to the arduino, all the matrix lights up with rainbow colors… Good to know it’s not broken.
Now I’ve just to understand why passing by the UsbART it doesn’t do the same…
