CP2110 EVALUATION KIT USER ’S GUIDE

1. Kit Contents

The CP2110 Evaluation Kit contains the following items:

CP2110 Evaluation Board
RS232 Serial Cable
USB Cable
DVD
Quick Start Guide

2. Relevant Documentation

Application notes can be found on the Interface Application Notes page for all fixed-function devices:

www.silabs.com/interface-appnotes.

AN721: CP210x/CP211x Device Customization Guide — Customize the VID, PID, serial number, and

other parameters stored in the CP2110 one-time programmable ROM.

AN433: CP2110 HID to UART API Specification — Provides function descriptions and examples for all of

the PC software functions that control the CP2110.

AN434: CP2110 Interface Specification — Describes the HID report format for CP2110 devices.

3. Software Setup

The Software Development Kit (SDK) for the CP2110 kit is included on the kit DVD. The latest version of this
installer can also be downloaded from the www.silabs.com/cp2110ek website. This package includes the following:

Device Customization Utility (AN721)
Documentation — data sheet, application notes, user’s guide, quick start guide, etc.
HidUartExample — Example software utilizing the CP2110 API interface described in AN433.
Library — repackaged HID DLL and CP2110 API DLL

The Windows installer should launch automatically after inserting the
appropriate directory on th e
system. The CP2110 is an HID device, so a driver does not need to be installed on most operating systems.

5. CP2110 Software Interface

The CP2110 is an HID device that uses the standard HID functions available in the operating system. To facilitate
this process in Windows, Silicon Labs packaged the standard HID functions into the SLABHIDDevice DLL in the
CP2110 software package. The HID report structure for the CP2110 is customized for the device and is not
compatible with other HID report structures, like a m ouse or keyboard. AN434, “CP2110 Interface Specification”
describes the custom HID report structure for the CP2110, and AN433, “CP2110 HID to UART API Specification”
describes the API software functions that can be used to read or write data and control the CP2110 from the PC.
The software application described in “6. CP2110 Windows Application” provides an example of how to use these
functions.

The CP2110 appears as an HID device in Device Manager as shown in Figure 2.
