EVM Overview
1 EVM Overview
1.1 Features
TSC2020EVM:
• Full-featured evaluation board for the TSC2020 resistive multiple touch screen controller (TSC)
• Modular design for use with a variety of DSP and microcontroller interface boards
TSC2020EVM-PDK:
• Easy-to-use evaluation software for Microsoft
®
Windows
®
XP
• Complete control of board settings
For use with a computer, the TSC2020EVM-PDK is a complete evaluation kit. This kit combines the
TSC2020EVM with the USB-based USB-MODEVM motherboard and evaluation software for use with a
personal computer.
The USB-MODEVM motherboard allows the TSC2020EVM to be connected to the computer via an
available USB port. This manual shows how to use the USB-MODEVM as part of the TSC2020EVM-PDK,
but does not provide technical details about the USB-MODEVM itself.
This manual covers the operation of both the TSC2020EVM and the TSC2020EVM-PDK. Throughout this
document, the abbreviation EVM and the term evaluation module are synonymous with the TSC2020EVM.
1.2 Introduction
The TSC2020EVM is manufactured in Texas Instruments' modular EVM System specification. It can be
connected to any modular EVM system interface card. The TSC2020EVM allows direct evaluation of the
TSC2020 performance and operating characteristics, in addition to rapid software development and
system prototyping. This EVM is compatible with the 5-6k Interface Board (SLAU104) from Texas
Instruments and additional third-party boards such as the NI Speedy-33™ from National Instruments
Corporation.
The TSC2020EVM-PDK is a complete evaluation and demonstration kit that includes a USB-based
motherboard, the USB-MODEVM interface board. This kit also contains evaluation software for use with a
personal computer equipped with Microsoft WindowsNT and XP operating systems. The
TSC2020EVM-PDK is a complete package that includes the following items:
1. TSC2020EVM board
2. USB-MODEVM board
3. Evaluation software installer and related documentation (downloaded from
ftp://ftp.ti.com/pub/evm-pdk/TSC2020/)
The TSC2020EVM is available as a stand-alone printed circuit board (PCB) or as part of the
TSC2020EVM-PDK, which includes a USB-MODEVM motherboard and software. As a stand-alone PCB,
the TSC2020EVM is useful for prototyping designs and firmware.
2 Analog Interface
For maximum flexibility, the TSC2020EVM is designed for easy interfacing to multiple analog sources by
means of different connection options.
The TSC2020 supports a 3x5 analog matrix resistive multiple touch screen. A 50-pin multiple touch screen
connector J4 (part number FH12A-50S-0.5SH) is installed on the TSC2020EVM PCB, and provides a
direct connection to a corresponding 50-pin flat cable found on resistive multiple touch screens. Figure 1
details the pinout of the 50-pin connector on the TSC2020EVM board, and also shows the suggested
connections to a 3x5 resistive multiple touch screen.
