## Project Overview
The **embedded-stm32-projects** repository focuses on bare-metal programming for the STM32L4 microcontroller. This means you will work directly with hardware without an operating system. The projects aim to provide a hands-on experience with embedded systems.
## Features
- **Bare-metal Programming**: Directly interact with hardware.
- **Custom Drivers**: Built for various peripherals.
- **Sensor Integration**: Use I2C and SPI protocols.
- **Interrupt Handling**: Efficiently manage asynchronous events.
- **FreeRTOS Ready**: Prepare your projects for real-time operating systems.
## Getting Started
To get started, clone the repository:
```bash
git clone https://github.com/hana0212/embedded-stm32-projects.git
```
Next, navigate into the project directory:
```bash
cd embedded-stm32-projects
```
For detailed instructions, refer to the [Releases](https://github.com/hana0212/embedded-stm32-projects/releases) section.

## Drivers
The drivers folder contains the essential code to interface with various peripherals. Each driver is modular, allowing for easy integration into your projects.
### I2C Driver
The I2C driver facilitates communication with multiple devices using the I2C protocol. It includes functions for:
- Initialization
- Sending data
- Receiving data
### SPI Driver
The SPI driver allows for high-speed communication with devices. It supports:
- Full-duplex communication
- Master and slave modes
### UART Driver
The UART driver enables serial communication. Key features include:
- Configurable baud rates
- Transmit and receive functions
## Sensors
The sensors folder includes example code for integrating various sensors. Each sensor module is designed to work seamlessly with the provided drivers.
### Temperature Sensor
This module demonstrates how to read temperature data using an I2C temperature sensor. The implementation includes:
- Sensor initialization
- Data reading functions
### Humidity Sensor
Similar to the temperature sensor, this module integrates a humidity sensor. It provides:
- Initialization code
- Functions to retrieve humidity data
## Interrupt Handling
Efficient interrupt handling is crucial for responsive embedded applications. The interrupts folder includes examples for managing hardware interrupts, such as:
- Timer interrupts for periodic tasks
- GPIO interrupts for button presses
Each example shows how to set up the interrupt service routine (ISR) and handle events.
## FreeRTOS Integration
For projects that require multitasking, FreeRTOS can be integrated. The freertos folder contains example tasks that demonstrate:
- Task creation
- Task scheduling
- Inter-task communication
These examples are ready to be modified and expanded based on your needs.
## Building the Projects
To build the projects, ensure you have the necessary tools installed, such as:
- ARM GCC toolchain
- Make utility
Use the following command to compile a project:
```bash
make
```
This command will generate the binary files needed to upload to your STM32L4 microcontroller.
## Testing the Projects
Once built, you can upload the binary to your microcontroller using tools like ST-Link or OpenOCD. Follow these steps:
1. Connect your STM32L4 to your computer.
2. Use the appropriate flashing tool.
3. Load the generated binary file.
For further testing, you can use serial output to debug and monitor your application.
