issues with new uno board

Post by CharlieJ »

I bought a second uno and my program does not syc with it , I changed the delays of the blink sketch and it gives an error code. it tells me" stk500_getsync(): not in sync: resp=0x30" I know it in the comm port but i only see one comm port under tools>serial port. What did I do wrong? Charlie J
This example code is in the public domain.
*/

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(3000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(3000); // wait for a second
}

Hi Charlie,

The sync error is not related to any change you made to your sketch. It is usually due to a communication problem between your computer and the UNO. Since it is a new board, the computer probably assigned it to a different COM port. Make sure that you have that COM port selected in "Tools->Board Type".

I looked over the info and decided to reload the drivers. I had gotten the uno rev3 board and I guess its a little different so it needed a new driver. also I noticed a couple of extra pins in the headers, I have not looked at the web site for answers so what are they for? thanks Charlie J

The extra pins are for compatibility with the Mega. They are duplicates of other pins on the header, so the R3 is still backwards compatible with the older UNO.
