Sensor and Actuator Interfacing with STM32

Read this course at: https://siliconwit.com/education/sensor-actuator-interfacing-stm32/

A hands-on course covering sensor, actuator, and communication module interfacing on the STM32 Blue Pill (STM32F103C8T6) using STM32CubeIDE and HAL. Topics include GPIO, ADC, PWM, I2C, SPI, UART, RFID, stepper motors, DMA, CAN bus, and a multi-sensor capstone project.

How to Contribute

All commands below work on Linux, macOS, and Windows (using Git Bash, PowerShell, or Command Prompt with Git installed).

For Team Members (with push access)

First time setup (clone the repo once):

git clone https://github.com/SiliconWit/sensor-actuator-interfacing-stm32.git
cd sensor-actuator-interfacing-stm32

Every time you start working:

git pull origin main

Always pull before making changes. This avoids conflicts with other contributors.

After making your changes:

git add .
git commit -m "Brief description of what you changed"
git push origin main

If you get a push error (someone pushed before you):

git pull origin main

Git will merge the changes automatically in most cases. If there is a conflict, Git will mark the conflicting lines in the file. Open the file, choose which version to keep, then:

git add .
git commit -m "Resolve merge conflict"
git push origin main

Tips to avoid conflicts:

• Always git pull origin main before you start working
• Push your changes as soon as you are done, do not hold onto uncommitted work for long
• Coordinate with other contributors so two people are not editing the same file at the same time

For External Contributors (without push access)

1. Fork the repository: SiliconWit/sensor-actuator-interfacing-stm32
2. Clone your fork:

   git clone https://github.com/YOUR-USERNAME/sensor-actuator-interfacing-stm32.git
   cd sensor-actuator-interfacing-stm32

3. Make your changes and commit:

   git add .
   git commit -m "Brief description of what you changed"
   git push origin main

4. Open a Pull Request against main on the original repository
5. Describe what you changed and why in the PR description

Content Standards

• All lesson files use .mdx format
• Do not use <BionicText> in this course
• Code blocks should include a title attribute:

  ```c title="main.c"
  HAL_GPIO_WritePin(GPIOB, GPIO_PIN_12, GPIO_PIN_SET);
  ```

• Use Starlight components (<Tabs>, <TabItem>, <Steps>, <Card>) where appropriate
• Keep paragraphs concise and focused on practical application
• Include working code examples that readers can compile and flash
• All pin assignments must be valid for the STM32F103C8T6

Local Development

Clone the main site repository and initialize submodules:

git clone --recurse-submodules <main-repo-url>
cd siliconwit-com
npm install
npm run dev

To test a production build:

npm run build
