The program achieved a 4-way simultaneous acquisition with PCF8591T AD inputs. By P3.2, P3.3 two buttons to switch the display of the AD input channels. By precision adjustable resistors S19 (P3.2) displays the values ​ ​ of pressure. Light sensitive resistor and the thermistor at S20 (P3.3) is displayed. We can adjust the precision adjustable resistor, or blocking the photoresistor, or hand contact temperature sensitive resistor, the digital display AD acquisition value will be a corresponding change.
