My script causes a lockup

There seems to be an issue with not only floating point math operations and printing the results, but I can't even get simple arithmetic to work if variables are used...

I've tried to read analog values and perform simple math operations on the variables holding these values, but the Arduino keeps locking up on me. For example, with the following code:

Code:

int analogPin = 1;
int val = 0;
int val2 = 0;

void setup() {
  Serial.begin(9600);
}

void loop() {

  val = analogRead(analogPin);
  Serial.print("val = ");
  Serial.println(val);
 
  val2 = val + 5;
  Serial.print("val2 = ");
  Serial.println(val2);
 
  delay(1000);
}

The program will hang up once it reaches the val2 definition.

I've tried both Linaro Ubuntu 11.10 (image version 1.3) and 12.04 LTS (image version 2.0), but I get the same hanging up with both. Is there some sort of update to the Arduino IDE 1.5.4 that I need to install?

FYI...I'm using a UDOO Dual Lite.

 

Re: It seems floating point is bad?

Try switching from Pin 1 to using Pin 2, let us know how you get on after that.

P.S. Please don't hijack someone else post unless it's a shared thread (like the HDMI Offical Issues thread) or you have exactly the same issue, it just confuses the issue.

 

I wasn't hijacking... The issue is the Serial class is causing the Arduino to lock up. FFS the example code from the Udoo blog doesn't even work for the same reason...
