Arduino Due Connector description

Where can I find a description of each connector on the Arduino Due board?
Thanks,
Charles

google "arduino due pinout", look in image results, pick one you like. There are lots of beautiful charts showing the possible functions of each pin.

I am trying to use the Atmel Studio with GCC compiler to load some code into the board. I have an Atmel SAM ICE but not too sure how to connect it to the boad. I just want to be able to set some breakpoints and check if the compiler can handle 64 bit floating point.

I just want to be able to set some breakpoints and check if the compiler can handle 64 bit floating point.

Declare a variable as double (means double float) and you are done.

Here is an example sketch to show the exact precision a Sam3x can handle with double floats:

/****************************************************/
/*    Arduino DUE handling of 64-bit double float   */
/****************************************************/
void setup() {
  Serial.begin(250000);
  
  float var1 = -2.0 / 3.0;
  Serial.println(var1, 10); // 7 digits precision 
  double var2 = -2.0 / 3.0;
  Serial.println(var2, 20); // 15 digits precision 
}

void loop() {
}
