This repository contains the source code for the MCU Peripheral Drivers development project. Visit the "MCU Peripheral Drivers" section on my website for more details: https://jackklee.com/mcu-peripheral-drivers.
- Developed MCU peripheral drivers (GPIO, SPI, I2C, USART) from scratch on the STM32F407G-Discovery board, along with comprehensive test applications to ensure their reliability and applicability for real‐world projects
- Used STM32CubeIDE for software development, a logic analyzer for testing, and the on‐board ST‐LINK/V2 debug circuitry for debugging
- Please see the LCD Digital Clock project to observe how these drivers are utilized in a real-world embedded systems project
- Operating system: Ubuntu 22.04 LTS
- Integrated Development Environment (IDE): STM32 CubeIDE Version 1.10.1
- Application layer consists of test applications designed to verify the proper functionality of the GPIO, SPI, I2C, and USART peripheral drivers for the STM32F407xx MCU.
- Hardware abstraction layer includes the device-specific header file for STM32F407xx MCU, along with the GPIO, SPI, I2C, and USART peripheral drivers. This layer provides the application layer with a range of APIs to control the respective MCU peripherals.
