Overview

The 40-pin header allows StarFive single board computers, including both StarLight and VisionFive, to interface with a variety of external components, which enables developers to create their projects. This document is intended to:

• introduce the 40-pin header as described in this chapter.
• provide instructions to configure and debug GPIO, I2C, SPI, PWM, and UART, as described in GPIO Operations, I2C Operations, SPI Operations, PWM Operations, and UART Operations chapters.
• provide peripheral examples to use the 40-pin header, as described in the Peripheral Examples chapter.
