As the picture shows, this is a electrical digital meter panel circuit. As a 8 bits A/D converter, PIC16C711 has two input ports. Among them, AD0 is voltage input port and AD1 is scale selecting input port. If AD1 is connected to ground, it will show a scale of 0.00 V to 5.10 V with resolution of 20 mV. If AD1 is connected to 2.5V voltage, it will show a scale of 00.00 V to 12.75 V with the resolution of 50 mV. If AD1 is connected to 5 V, it will show a scale of 00.0 V to 25. 5 V and the resolution will be 100 mV. Under the common condition, PIC16C711 display accuracy is ±1/2LSB. It can drive four seven-port LED at the same time and only one LED can be lighted at one time. The input voltages of PIC16C711 are 5 V, 12 V and 25 V.
