Topic: uploading through UNO to Rainbowduino (Read 1 time) previous topic - next topic

g'day, i got my hands on an arduino uno and removed the chip from it, and hooked up the rainbowduino, ive tried to use it as a bridge to the rainbowduino so i can upload newer firmware and code to my rainbowduino but the upload always fails, is it because of the arduino uno?

if not then how would i go about getting to work?

i asked around alot of places an answer is extremely elusive and would like to get to the bottom of this and make it work and havent really gotten a solid answer, starting to think buying all these electronics was pretty much a waste of time :/

"You can try like this.
1.Upload a blank sketch to Arduino Uno to disable Arduino Uno Serial Port.
void setup()
{
DDRB = 0;
DDRC = 0;
DDRD = 0;
}

void loop()
{
}

2.And connect as:

Rainbowduino <--> Arduin Uno
TX <-->TX
RX <-->RX
GND<-->GND
VCC<-->5V
DTR<-->RESET

3.select Arduino Duemilanove or Nano with ATmega328 in Arduino IDE.
4.upload a sketch...

Good luck
