Introduction to Blinka (Python Library)
In the MCU world, we can use MicroPython or CircuitPython for Python embedded programming. For Linux boards, there is an open-source project initiated by Adafruit called Blinka, which aims to provide a universal Python library for GPIO-based embedded programming on Linux boards. Blinka currently supports Raspberry Pi, Jetson Nano, and many other Linux development boards on the market.

In short, after installing the Blinka library on the WalnutPi, you can easily use Python libraries to work with various GPIO peripherals on the development board. The WalnutPi comes with Blinka pre-installed in the factory system, located at /usr/lib/walnutpi/Adafruit_Blinka:
The pre-installed Blinka on the WalnutPi has been customized and adapted to the WalnutPi's CPU.
