VIM 5 WiringPi
Introduction
WiringPi is a C++ library for Raspberry Pi, we port it to Khadas SBC, With this library you can use many of the functionalities provided by the GPIO header: digital pins, SPI, I2C, UART, etc.
WiringPi Instructions
There are two methods here, via command line or C program.
