UDOO freeze on simple calculation

Hi All,

I've bought UDOO dual. 8 Gb SD card and ubuntu 12.04.
I'm using bluetooth mouse & keyboard, and it works. I write this using Udoo ubuntu browser.

From internal ubuntu I've already install Arduino IDE.
Trying blinking example, it works.

and then I put HSM20G (humidity and temp sensor).
Simple example reading analogRead , then output going into serial.... It Works.
and now it's time to calculate from analogRead into human readable.

Here 's my code :


int sensorPin = A0;
int suhuPin = A1;
int ledPin = 13; // select the pin for the LED
int sensorValue = 0, suhuValue = 0; // variable to store the value coming from the sensor
float RH = 0;

void setup() {
// declare the ledPin as an OUTPUT:
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
}

void loop() {
// read the value from the sensor:
sensorValue = analogRead(sensorPin);
suhuValue = analogRead(suhuPin);
// turn the ledPin on
digitalWrite(ledPin, HIGH);
delay(sensorValue);
RH = (0.1515 * sensorValue) - 12.0;
// turn the ledPin off:
digitalWrite(ledPin, LOW);
// stop the program for for <sensorValue> milliseconds:
Serial.print(sensorValue,1);
Serial.println(" Sensor");
Serial.print(suhuValue,1);
Serial.println(" Suhu");
//Serial.print(RH,1);
Serial.println(" %RH");
//Serial.print(TinF,1);
Serial.println(" F");
delay(1000);
}


it always freeze on
RH = (0.1515 * sensorValue) - 12.0;

when I remark / delete this... everything going fine....

Anybody knows what I missed ?

 

Found the solution....
Compile through another PC...
and zap...
It works...
