An A/D sampling procedures, the use of external 22.1184MHz crystal. Use of the timer interrupt, once per second, and sampling interrupt. Sampling AIN0,1 and temperature channel signals and display the voltage and temperature values ​ ​ on the LCD. By manually adjusting the potentiometer VR2, the voltage value of the observed variation.
