Hi, I got a Rainbowduino 328, I followed the instructions to get it going on the mTx Control rngtng.com/mtXcontrol/ but unfortunately no luck. I just get an stk500 error when trying to upload the firmware.pde sketch to the Raindbowduino throw the Arduino. Probably in the process, I corrupted the boot loader as I no longer get the default pattern on the Rainbowduino 8x8 matrix, it’s just blank now with no lights. so I figured I’d upload the bootloader back using the Arduino IDE and my AVRISP MKii. I was able to flash the bootloader back to an Arduino 328 so I know the AVRISP Mkii is working but when trying to upload the bootloader or any sketch for that matter to the Rainbowduino 328, I get this:
avrdude: stk500v2_command(): command failed
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
Any help would be appreciated, thanks.
