AN978: CP210x USB-to-UART API Specification

2022-04-19

This document describes the API for the CP210x Manufacturing Library, used to configure CP210x devices, and the CP210xRuntime Library, used to operate the devices' GPIOs during run-time.
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 GPIOs.
●KEY POINTS
■Silicon Labs provides public libraries to access all available features on CP210xdevices.
■Use the CP210x Manufacturing library to configure a device's programmable settings.
■Use the CP210x Runtime library to control a device's GPIOs at runtime.
