Running Python directly on FreeRTOS isn't straightforward because FreeRTOS is a real-time operating system (RTOS) designed for embedded systems, typically programmed in C or C++. However, you can achieve a Python-like experience on FreeRTOS using MicroPython. Here’s how:


Running MicroPython on FreeRTOS

MicroPython is a lightweight Python interpreter designed for microcontrollers. It can be ported to run on top of FreeRTOS.

Steps to Run MicroPython on FreeRTOS:

  1. Get the MicroPython Source Code

    Clone the MicroPython repository:

    git clone <https://github.com/micropython/micropython.git>
    cd micropython
    
  2. Set Up a FreeRTOS-Compatible Board

  3. Modify FreeRTOS Configuration (if needed)

  4. Build MicroPython for Your Target

    For ESP32:

    cd ports/esp32
    make submodules
    make BOARD=GENERIC
    
    
  5. Flash MicroPython to Your Device

    esptool.py --port /dev/ttyUSB0 write_flash 0x1000 firmware.bin
    
  6. Run MicroPython on FreeRTOS

    1. Once flashed, open a serial terminal:

      picocom /dev/ttyUSB0 -b115200
      
    2. You should see a Python REPL (interactive prompt).

Alternative: Running a Python Script on FreeRTOS

If you don’t want full MicroPython, you can:

Run Python on an ESP32 with FreeRTOS

Method 1: Running MicroPython on ESP32 (with FreeRTOS)

ESP32 already runs FreeRTOS internally, so you can use MicroPython, which is optimized for microcontrollers.

Install ESP-IDF (ESP32 Development Framework)
