We highly recommend using the ESP-IDF tools rather than Arduino. The lab and project tutorials are based on ESP-IDF tools.

Getting Started with ESP32-C5

Step 1: Install ESP-IDF

The ESP-IDF (IoT Development Framework) is the official programming guide for ESPRESSIF ESP32-C5. Follow the step-by-step installation process tailored to your operating system. It is recommended to install ESP-IDF under the default path (~ or /Users/yourusername/).

Installation Guide: ESP32-C5 Getting Started

To simplify usage, create an alias for export.sh by following these steps:

1. Open your shell profile file (.profile, .bashrc, .zshrc, etc.) and add the following line:

    alias get_idf='. $HOME/esp/esp-idf/export.sh'
   

2. Apply the changes by restarting your terminal or running:

    source ~/.bashrc  # Or replace with your profile file
   

3. Now, you can quickly load the ESP-IDF toolchain by typing:

    get_idf
   

Step 2: Run the Blinking LED Example

Once ESP-IDF is installed, test it by running the blinking LED example.

1. Navigate to the ESP directory and copy the example project:

    cd ~/esp
    cp -r $IDF_PATH/examples/get-started/blink .
    cd blink
   

2. Set the target device:

    idf.py --preview set-target esp32c5
   

3. Identify the device port:

   • Check the port by running:

     ls /dev/cu*
     

   • On macOS, it typically appears as /dev/cu.usbmodem1101.

4. Build the firmware:

    idf.py build
   

   If there are no errors, the build will generate firmware binary .bin files.

5. Flash the firmware to your ESP32-C5:

    idf.py -p /dev/cu.usbmodem1101 flash  # Replace with your actual port
   

6. Monitor the output to confirm the LED is blinking:

    idf.py -p /dev/cu.usbmodem1101 monitor  # Replace with your actual port
   

Once you see the LED blinking, you have successfully set up your ESP32-C5!
