📄️ GPIO Introduction
Let's take a detailed look at the Walnut Pi's GPIO, i.e., its 40-pin GPIO header (similar to Raspberry Pi). The Walnut Pi is already a great single-board computer, but the GPIO design makes it easier for users to perform various DIY electronic projects, giving you an experience similar to using a powerful microcontroller development board.
📄️ GPIO Command Operations
We provide a set of commands for quickly operating GPIO from the command line. This guide mainly introduces how to use these commands.
📄️ Switch GPIO Function
Some pins carry functions such as I2C, UART, SPI, etc. You need to use the set-device command to enable the configuration before you can use Python or C for embedded programming applications.
📄️ PWM
This guide mainly introduces how to use the onboard hardware PWM functionality, based on the general Linux PWM operation method.
