EVM Overview

1.1

Features

 

Full-featuredevaluation board for the TSC20074-wireresistive touch screen controller (TSC).

 

Modular design for use with a variety of DSP and microcontroller interface boards.

 

The TSC2007EVM-PDKis a complete evaluation kit, which includes aUSB-basedmotherboard and

 

evaluation software for use with a personal computer running Microsoft Windows™ operating systems.

1.2

Introduction

 

The TSC2007EVM is in the Texas Instruments modular EVM form factor, which allows direct evaluation of

 

the performance and operating characteristics of the TSC2007, and eases software development and

 

system prototyping. This EVM is compatible with the 5-6KInterface Evaluation Module (SLAU104) from

 

Texas Instruments and additional third-partyboards such as the NISpeedy-33™from National

 

Instruments Corporation. (www.ni.com)

The TSC2007EVM-PDKis a complete evaluation/demonstration kit, which includes aUSB-basedmotherboard called theUSB-MODEVMinterface board and evaluation software for use with a personal computer running Microsoft Windows operating systems.

2Analog Interface

For maximum flexibility, the TSC2007EVM is designed for easy interfacing to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-KandTSM-110-01-T-DV-Pprovide a convenient10-pin,dual-rowheader/socket combination at J1. This header/socket provides access to the analog input pins of the TSC. Consult Samtec atwww.samtec.com, or call1-800-SAMTEC-9for a variety of mating connector options.
