Embedded C Programming for STM32 PART – 4

Welcome to another exciting tutorial on embedded systems! 🎉

In this video, I explain step-by-step how to interface dual 7-segment displays along with increment and decrement switches to the STM32F401RET microcontroller. This tutorial covers everything from the basics of 7-segment displays, GPIO pin configuration, to writing and debugging the code for STM32.

🔧 What You’ll Learn:

7-Segment Display Basics: Understand the working and pinout of dual 7-segment displays.
Increment and Decrement Switch Functionality: How to detect button presses to increment and decrement numbers on the displays.
STM32 GPIO Programming: Configure pins for driving the displays and reading the switches.
Simulation in Proteus: See how to verify the functionality before hardware implementation.

🛠️ Tools Used:

Microcontroller: STM32F401RET
IDE: STM32CubeIDE with HAL libraries
Simulation Software: Proteus Design Suite
