AN978: CP210x USB-to-UART API Specification

PublishTime：2020-09-23

This document describes the API for the CP210x Manufacturing Library, used to configure CP210x devices, and the CP210x Runtime Library, used to operate the devices' GPIOs during runtime.
The Silicon Labs CP210x USB-to-UART bridges are devices that communicate over the Universal Serial Bus (USB) to perform Universal Asynchronous Receiver/Transmitter (UART) data transfers. These devices have many programmable options that can be configured via USB. These devices also often include flexible GPIO functions that can be configured and accessed via USB during runtime. Silicon Labs provides libraries that can be used to configure these devices and access their GPIO.
KEY POINTS：
• Silicon Labs provides public libraries toaccess all available features on CP210x devices.
• Use the CP210x Manufacturing library toconfigure a device's programmable settings.
• Use the CP210x Runtime library to controla device's GPIOs at runtime.
