Embedded C Programming for STM32 PART – 6

Welcome to another exciting tutorial on embedded systems! 🎉

In this video, I explain how to interface a 16×2 LCD with the STM32F401RETx microcontroller using KEIL µVision for Embedded C programming (without HAL). You’ll learn how to connect the LCD, configure GPIO pins, write Embedded C code, and simulate the project in Proteus to verify its functionality before implementing it on hardware.

🔧 What You’ll Learn:

16×2 LCD Interfacing: How to connect and control an LCD using the STM32F401RETx.
GPIO Configuration: Setting up STM32 GPIO pins for LCD control (data, RS, RW, and Enable).
Embedded C Programming: Writing efficient code for initializing and controlling the LCD.
Proteus Simulation: Simulating the LCD display to ensure proper operation before hardware testing.

🛠️ Tools Used:

Microcontroller: STM32F401RETx
IDE: KEIL µVision (without HAL)
Simulation Software: Proteus Design Suite
