CP2110/4 HID-TO-UART API SPECIFICATION
1. Introduction
The Silicon Labs HID-to-UART interface library provides a simple API to configure and operate CP2110 and
CP2114 devices. The library provides interface abstraction so that users can develop their application without
writing any USB HID code. C libraries implementing the CP2110 and CP2114 Interface Specification are provided
for Windows 2000 and later, Mac OS X 10.5 and later, and Linux. Similarly, various include files are provided to
import library functions into C#.NET and Visual Basic.NET. Refer to Table 1 for complete details.
