I have one more question:

I need to switch on a red led if the temperature is over 100°C

I simply did this:

Code:
if(temp1 > 100)         
{
         output_high(PIN_b7);     //switch on the red led
         output_low(PIN_b6);      //switch off the green led
}
if(temp1 < 100)             
{
         output_high(PIN_b6);     //switch on the green led
         output_low(PIN_b7);      //switch off the red led
}


But it don't work...How is it possible??

Thanks Wink
