STM32 Black Pill with 16*2 LCD Tutorial

Introduction

This tutorial will guide you through displaying text on a 16x2 LCD using the STM32 Black Pill development board and STM Cube IDE, without the need for an I2C module. We’ll be using HAL (Hardware Abstraction Layer) programming for this purpose.

Requirements

• STM32 Black Pill board
• USB – Type C cable
• 16x2 LCD
• Potentiometer (10kΩ)
• Jumper wires (M-M, F-M)
• Breadboard

Step 1: Setting Up STM Cube IDE

First, ensure that you have the STM Cube IDE installed on your computer. Create a new project and select the STM32F103C8T6 MCU, which is the microcontroller used in the Black Pill board.

Step 2: Configuring the Pins

Configure the pins for the LCD in the IDE. You’ll need to set up the GPIO pins that will interface with the LCD’s data and control lines.

Step 3: Writing the Code

Here’s a simple code snippet to initialize the LCD and display “YOUR NAME”:

Step 4: Compiling and Uploading

Compile the code and upload it to your STM32 Black Pill board using a USB-Type C cable.

Step 5: Verifying the Output

Power up your board and check the LCD. You should see “YOUR NAME” displayed on the screen.
