ITO F

1. Introduction

The ITO Film Evaluation Kit (KeymatEK) implements a demo using a thin film or plastic printed with Indium Tin

Oxide (ITO). The evaluation board features the Silicon Labs C8051F800 with Shin-Etsu “JCS” ITO Film material

printed with a standard keymat pattern. The shapes, patterns, color ink graphics, and thicknesses of the film may

all be customized for the application. For convenience, the board includes the Silicon Labs ToolStick Base Adapter

circuitry for debugging, a CP210x USB-to-UART bridge for communication, and the QuickSense

for sensor performance monitoring and threshold adjustment.

2. Kit Contents

The ITO Film Evaluation Kit contains the following items:



3. Getting Started

3.1. CP210x USB to UART VCP Driver Installation

The ITO Film Evaluation Board includes a Silicon Laboratories CP2103 USB-to-UART Bridge Controller. Device

drivers for the CP2103 need to be installed before the PC software can communicate with the evaluation board

over the USB connection. The CP210x Virtual COM Port (VCP) drivers can be downloaded from the Silicon Labs

“Software Downloads” website (www.silabs.com/mcudownloads). After downloading the drivers, launch the

“unpacker” utility.

1. Follow the steps to copy the driver files to the desired location. The default directory is C:\SiLabs\MCU\CP210x.

2. The final window will give an option to install the driver on the target system. Select the “Launch the CP210x VCP Driver

3. If selected, the driver installer will now launch, providing an option to specify the driver installation location. After pressing

4. If the “Launch the CP210x VCP Driver Installer” option was not selected in step 3, the installer can be found in the location

5. If needed, the driver files can be uninstalled by selecting “Silicon Laboratories CP210x USB to UART Bridge Driver

3.2. Running the Demo

Follow these steps to run the ITO Film Evaluation Board Demo:

1. Install the Silicon Labs CP210x USB to UART VCP driver on the target PC following the directions in Section 3.1.

2. Once the VCP driver is installed, connect the F800 ITO Film Board COMM (P2) to the PC using a standard USB cable. The
