Multiplexing

In 7 segments display multiplexing segments of all the digits are tied together and the common pins of each digit are turned ON separately by the microcontroller. When each digit is displayed only for several milliseconds, the eye cannot tell that the digits are not ON all the time.

For example, to display the number 12, we have to send 1 to the first digit and enable its common pin. After a few milliseconds, number 2 is sent to the second digit and the common point of the second digit is enabled. When this process is repeated continuously, it appears to the user that both displays are ON continuously.

Project: Multiplexing With 7-Segments Display

The 7 segments display are connected to PORTC of a PIC16F877 microcontroller. Segments a to g of the display are connected to the microcontroller through 190-ohm current limiting resistors and the microcontroller operated from an 8MHz crystal. Each digit is enabled using a BC108-type transistor connected to pins RD6 and RD7 of the microcontroller.
