Arduino mega 2560

Using Arduino IDE 1.x

Hi.

I acquired an arduino mega 2560 couple weeks ago. Firstly I tried to upload code to the board with the arduino environment 1.0.1, aparently it uploads normally , the rx and tx leds blink for a short period.

Then when i open the serial monitor it doesnt appeear nothing.

After that i uploaded the 1.0.5-r2 environment , as i tought it could be the problem and tride to upload to board from that but it does the same.

I have a leonardo, and everything is fine with this one.

Things i am sure i did:

Choose the right board in the arduino environment;

Bluetooth disabled;

right com port selected.

Thanks in advance

The code im trying to upload is a very simple routine just to see if it works fine:

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly: 
  Serial.println('A');
  delay(1000);
}

You're missing

Serial.begin(9600); // or some similar speed

in setup.

Thanks.

Stupid me :blush:

From the moment i open serial monitor till start printing the first caracter it takes 10 seconds or so.

Is this normal?

Yes. Depends on how long the bootloader waits to decide a download is not happening.
When the serial monitor opens it resets the Arduino. On my PC it looks to be resetting it several times.
