Task 3.C

In this tutorial, we'll work on STM32 microcontrollers by learning how to display text on a 16x2 LCD without using an I2C module. We'll use the STM32 Black Pill board and STM32CubeIDE to write HAL (Hardware Abstraction Layer) code to communicate with the LCD and display the text "YOUR NAME".

1. STM32 Black Pill board (STM32F401C)
2. 16x2 LCD display
3. Jumper wires
4. Breadboard

• Install STM32CubeIDE on your computer.
• Create a new project for your STM32 Black Pill board.

• Use jumper wires to connect the LCD to your STM32 board.
• Connect data pins (D4-D7) and control pins (RS, RW, EN).

• Open STM32CubeMX from within STM32CubeIDE.
• Assign GPIO pins for the LCD.
• Set them as outputs.

• In STM32CubeMX, configure GPIO outputs and timers if needed.
• Save and generate code.

• In STM32CubeIDE project, write code to initialize GPIO pins and LCD.
• Write functions to send commands and data to the LCD.

• Write a function to display "YOUR NAME" on the LCD.
• Make sure it positions the cursor correctly.

• Connect your board to your computer and upload the code.
• Power up your LCD and ensure it's connected properly.

We've learned how to interface a 16x2 LCD with an STM32 microcontroller (specifically the STM32 Black Pill board) without using an I2C module. we've used STM32CubeIDE and STM32CubeMX to generate the necessary initialization code, and then written HAL code to control the LCD and display text on it. This foundational knowledge opens up many possibilities for creating embedded projects with STM32 microcontrollers and various peripherals.
