📄️ GPIO Introduction
Let's take a detailed look at the WalnutPi's GPIO, which is the 40-pin GPIO header (similar to the Raspberry Pi). The WalnutPi is already a great single-board computer, but the GPIO design makes it easier for users to use the WalnutPi for various DIY electronics projects, giving you an experience comparable to a powerful microcontroller development board.
📄️ GPIO Command-Line Operations
We provide a set of commands for quickly operating GPIO from the command line. This section mainly introduces how to use these commands.
📄️ Switching GPIO Functions
Some pins have I2C, UART, SPI and other functions. You need to use the set-device command to enable them before using Python or C for embedded programming.
📄️ PWM
本篇主要介绍如何使用板上的硬件PWM功能，基于linux下对pwm的通用操作方式
