How to Control an LED Bar with 74HC595 Shift Register using SPI Protocol on STM32 

This project integrates the STM32 microcontroller with the 74HC595 shift register to develop a sophisticated LED bar-graph display system. Leveraging the STM32's GPIO pins and SPI interface, the project efficiently manages the 74HC595 to control a series of LEDs configured in a bar-graph layout.
