74HC595 Interfacing with 7-segment Display and PIC16F877A
In this article, we will learn how to make 74HC595 Interfacing with 7-segment Display and PIC16F877A.
In the last post, we learned how to make Seven Segment Counter Display with PIC Microcontroller.
Components Required:
- Shift register (74HC595)
- 7-segment display
- Microcontroller (PIC16F877A)
- Resistors (for current limiting)
- Power supply
- Connecting wires
How it works:
The PIC16F877A has a limited number of output pins, which might not be sufficient to directly drive a 7-segment display. The 74HC595 shift register helps expand the available outputs. It takes in serial data from the microcontroller and converts it into parallel output that can control the segments of the 7-segment display.
74HC595 Interfacing with 7-segment Display:
Usages:
- Output Expansion
- Display Multiplexing
- Reduced Pin Usage
- Educational Purposes
- Embedded Systems
