If you are experiencing problems with the touch sensor, you can use the diagnostic utilities provided to test the system.
3M™ Multi-Touch Chassis Display User Guide • If you are writing your own drivers, you should provide your own video alignment tool. Use the Paint program (Start→ Programs→ Accessories→ Paint) to determine if you have multi-touch operation. Retest the accuracy after you perform a calibration. 3M Touch Systems, Inc.
3M™ Multi-Touch Chassis Display User Guide 29 APPENDIX A 3M™ PX USB Controller Communications This appendix is intended for software developers only and discusses the fundamentals of communicating with the 3M™ PX controller. The firmware commands, which are usually issued by a driver or utility program on the host system, control the operation of the controller. This appendix lists the recommended firmware commands and describes how to use each of these commands.
3M™ Multi-Touch Chassis Display User Guide You need to know product ID (0506H) and the vendor ID (0596H) to write your own driver. These values are required for identifying the controller. Receiving Reports from the Controller The controller sends a variety of reports to the computer. The first byte of each report is the Report ID that defines the structure and content of the report. The controller sends some reports as a direct response to a computer request (synchronous).

3M™ Multi-Touch Chassis Display User Guide 37 APPENDIX B 3M™ PX Serial Controller Communications This appendix is intended for software developers only and discusses the fundamentals of communicating with the 3M™ PX serial controller. The firmware commands, which are usually issued by a driver or utility program on the host system, control the operation of the controller; however developers can enter these commands directly. This appendix: • • • • Describes the controller default settings.
3M™ Multi-Touch Chassis Display User Guide Data Format Data format refers to the type of packet the controller uses to send the X/Y touch coordinates to the host system. Format Tablet Multi-Touch is the default format for the 3M™ PX serial controller. In Format Tablet Multi-Touch, the controller sends 6 bytes per point and provides the most rapid response time to a touch. Note that 3M MicroTouch Software automatically sets communications parameters to N81.
3M™ Multi-Touch Chassis Display User Guide 39 3M Touch Systems recommends that the touch driver generate an interrupt as each packet in the data stream arrives. Because touchdown and liftoff events are specially coded, your software can generate mouse events that correspond to what the user is doing. This enables instant feedback and prevents data loss.
3M™ Multi-Touch Chassis Display User Guide Receiving Responses from the Controller After executing a command, the controller returns a response or acknowledgment to the host system. Each controller response consists of a header, the command response, and a terminator in the following format: Command Response Note: The following descriptions of header, response, and terminator, use 3M Touch Systems terminal emulator key sequences.
3M™ Multi-Touch Chassis Display User Guide 41 Firmware Commands Developers may use this information when writing touch applications, developing custom drivers or touch configurations, or testing their touch systems. Developers can use firmware commands to initialize the controller, select operating modes, specify data formats, and execute diagnostic functions. Caution: This document assumes you are familiar with firmware commands and how to use them.
3M™ Multi-Touch Chassis Display User Guide Calibrate Syntax: CX Response: 1 Valid point response. A Valid Point Response (‘1’) signifies that a touch coordinate was detected and is in range of the expected screen target area. Two valid point responses indicate successful calibration. 0 Invalid point response An Invalid Point Response (‘0’) is returned if the touch coordinate is out of range.
3M™ Multi-Touch Chassis Display User Guide 43 Guidelines for Calibrate Command Here are several guidelines for using the Calibrate commands: • The controller uses the data immediately before liftoff to register a calibration touch. Therefore, you can touch the coordinate target, hold for a few seconds, and then lift off. Instructing users to touch this way results in a more accurate calibration. • The controller stores the data in non-volatile memory (NOVRAM).
3M™ Multi-Touch Chassis Display User Guide Get Copyright Syntax: Q101 Response: Copyright © 2011 3M. All rights reserved. Description: This command is used to get copyright information. Mode Down Up Syntax: MDU Response: 0 Positive response. Description: Limits touch reports to touchdown and liftoff events only. Mode Inactive Syntax: MI Response: 0 Positive response. Description: Turns off touch reports.
3M™ Multi-Touch Chassis Display User Guide 45 Use Z to determine that you are communicating with the controller or to make sure that a utility is communicating with the controller. Using this command does not affect the controller’s current operating parameters. Output Identity Syntax: OI Response: ADXxxx where: AD Xxxx Description: = Two ASCII characters that describe the type of 3M Touch Systems controller.
3M™ Multi-Touch Chassis Display User Guide Soft Reset Syntax: R Response: 0 Positive response. Description: Initializes the hardware and the firmware, causes the controller to stop sending data, and recalculates the environmental conditions (for example, stray and offset values). The Reset command also cancels the Calibrate command and returns the controller to normal operation. Unit Type UT Responds with an 8-character identity string.
