after reading through the guide, i tried hooking up the UartSB as shown and upload to the rainbowduino but i get this
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
any ideas?
i dont have any arduino’s laying around that i can remove the chip from so I cant do it via the freeduino programming route.
