AN978: CP210x USB-to-UART API Specification

This document details the Application Programming Interface (API) for Silicon Labs' CP210x USB-to-UART bridge devices. It covers the functionalities of both the CP210x Manufacturing Library, used for device configuration, and the CP210x Runtime Library, used for operating the devices' GPIOs during runtime.

The CP210x series bridges facilitate Universal Asynchronous Receiver/Transmitter (UART) data transfers over USB, offering extensive programmable options and flexible GPIO functions. Silicon Labs provides comprehensive libraries to manage these capabilities.

Key Features

Silicon Labs offers public libraries for complete access to CP210x device features.
The CP210x Manufacturing library is utilized for configuring device-specific programmable settings.
The CP210x Runtime library is used to control the device's GPIOs during operation.
