Example text

The output of the ADC (a 12-bit number) is stored in the lower bits of a 16-bit register (ADCBUF0). A while loop waits for the conversion process to be completed. Then the value in ADCBUF0 is read into the unsigned integer variable (adcvalue), converted into a floating-point variable (fadcvalue), and scaled by the 5-V ADC input range. Next, the floating-point voltage (fadcvalue) is converted into a temperature by subtracting off the bias voltage, dividing by the amplifier gain, and adding back a temperature equivalent to the bias voltage.
