CHAPTER 2

Enabling Your Multi-Touch Chassis Display

Windows® 7 USB Compatibility

3M Multi-Touch technology works seamlessly with the Windows® 7 operating system. The Multi-Touch display supports USB HID for direct communication. The C4267PW Multi-Touch Chassis Display leverages all the multi-touch functionality that is native to Windows® 7. Plug the display into a system running Windows® 7 and you'll quickly enter the world of true multi-touch functionality.

The C4267PW Multi-Touch Chassis Display is compatible with Windows® 7 with no additional software. Refer to Microsoft's Windows® 7 documentation for additional information.

All Other Platforms

When using a Windows® 7 serial connection or for Windows® XP, Vista or Linux operating systems (either USB or serial), 3M provides MicroTouch™ MT 7 Software for multi-touch drivers. This guide includes information for writing your own drivers to interface with the 3M Multi-Touch Technology.

Multi-Touch Application Support

Remember not all applications are multi-touch ready – Multi-touch behavior is a function of YOUR application. Check with your application vendor to determine if your software has multi-touch capability.

Installing 3M ^TM MicroTouch ^TM Software

Remember that Windows® 7 does not require any additional software to enable multi-touch functionality.

However, for Windows® XP, Vista or Linux® operating systems, 3M™ MicroTouch™ Software enables your C4267PW Multi-Touch Chassis Display to work with your computer. 3M™ MicroTouch™ Software includes a control panel for setting your touch sensor preferences and a diagnostic utility. If you are experiencing problems with the touch sensor, you can use the diagnostic utilities provided to test the system.

For more information on installing this software and using the control panel, refer to the 3M ^TM MicroTouch ^TM Software User Guide on the accompanying CD or on the corporate website at www.3m.com/touch.

Video Alignment

The Multi-Touch Chassis has been calibrated prior to shipment and the display as delivered does not require video alignment. You should be able to accurately touch icons on the sensor. If for some reason, you cannot do this, the touch sensor's active area may not be aligned to the underlying video.

Regardless of the operating system, after you connect your touch display:

- If you are using Windows® 7, you may calibrate by accessing the Software Diagnostic Utility (SDU) found on the enclosed CD.

Launch the SDU from the CD. Select the Tools menu and highlight Calibration. The screen below appears and you should touch the 2 targets as they appear. Press Escape to cancel Calibration.

- If you are using 3M™ MicroTouch™ MT 7 Software, launch the MT 7 Control Panel and follow the instructions on the Main tab. You'll be asked to touch 3 targets.

- 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.

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.

Overview of USB Firmware Communications

Developers may use this information when writing touch applications, developing custom drivers or touch configurations, or testing their touch systems. Developers can issue commands to initialize the controller, select operating modes, and execute diagnostic functions.

Note: This document assumes you are familiar with USB standards and modes of communication with USB devices, as well as firmware commands and how to use them. Executing some commands may alter the performance of your sensor and render it inoperable. You should be aware of the results before executing any firmware commands.

To optimize the performance of the PX controller and simplify the development of custom drivers, 3M Touch Systems recommends you use the commands listed in this appendix for current development.

Communication Basics

This section provides information on sending firmware commands to the controller and interpreting the responses that the controller returns. The default operation of the PX controller is USB Rev 2.0 full speed.

The USB command set is implemented by using vendor requests and vendor reports, i.e., vendor specific transactions. The controller issues some reports without prompting the computer. The computer can also send requests to the controller to change how it operates or receives information about the controller. The controller issues a synchronous report in response to some of these requests.

You need to know product ID (0530H) 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). The controller will also send some reports as the result of an external event, such as a touch (asynchronous).

Command Set

The USB command set is implemented by using HID Get Feature and Set Feature commands. The various requests and reports are grouped together by report size under a common feature ID.

The following table summarizes the available HID class requests.

Table 1. HID Class Requests Summary

HID Report	Command Name	bmRequest Type	bRequest	Feature Report ID	Report Subtype	Data Stage Bytes
Get Feature	GetStatus	0xA1 (D2H)	0x01	0x06	--	8
Set Feature	Calibrate	0x21 (H2D)	0x09	0x03	4	8
Set Feature	Reset	0x21 (H2D)	0x09	0x03	7	8
Set Feature	Restore Defaults	0x21 (H2D)	0x09	0x03	8	8
Get Feature	GetMaxCount	0xA1 (D2H)	0x01	0x12	--	2

Set Feature - Calibration

This is a command to do a Calibrate Extended style calibration. The controller will auto-orient on this 2 point calibration.

Table 2. Calibration Setup Stage

Offset Field	Size Value	Description
0 bmRequestType 1 0x21 Class,H2D,Interface
1 bRequest 1 0x09 Set Report
2 wValue 2 0x0303 Msb 03 = Feature		Lsb 03 = Feature Report ID

6 wLength 2 8 Always 8

Table 3. Data Stage

Offset	Field	Size	Value	Description
0	Report ID 1	0x03	Feature report ID
1	Report Subtype	1	0x04	Indicates a calibration request
2	bCalType	1	0x01	0x01 = Extended cal (CX)
3--7	Not used	5	0	Not used

The device stalls endpoint 0 if the command cannot be processed successfully. The request cannot be processed if an invalid calibration type is given in the wValue field. The request will also fail if the 2 calibration points do not fall within certain bounds established by the firmware. These bounds require that the 2 calibration points be in opposite quadrants of the sensor.

The host should issue a GetStatus request to determine the status of this request. The status report includes a command status byte which will be set as shown below.

Table 4. Calibration Response

Command Status Byte	Description
0 Calibration Failed
1 Controller is waiting for a touch in the lower left corner. Calibration software paints a target in the lower left corner.
2 Controller is waiting for a touch in the upper right corner. Calibration software paints a target in the upper right corner.
3 Calibration completed successfully.

The controller does not timeout waiting for touch. Use the Soft Reset command to abort the calibration.

Determining Target Areas

The default calibration targets (points) are located 12.5% (1/8) inward from the corners of the video image. For example, suppose the resolution of your Windows-based display is 1680 x 1050. The Calibrate Extended command calculates the amount to move inward as follows:

• Amount to move inward in the X direction: 1680 × 1/8 = 210
• Amount to move inward in the Y direction: 1050 × 1/8 = 131

The Calibrate Extended command then positions the first calibration target inward from the lower left corner (0,1049) and the second calibration target inward from the upper right corner (1679,0). The following illustration shows how the calibration targets are calculated for a Windows-based system. Your operating system may be different.

The illustration below shows the coordinates of the calibration targets and display corners. The corners show the video coordinates in parentheses and the touch screen coordinates in brackets.

Note: Other screen resolutions will scale proportionally. The touch coordinates will not change.

Get Feature - GetStatus

This is a request to send information that indicates the status of the controller. Among the uses for this request are determining whether there were any power on check errors and determining whether the last request was completed successfully.

Table 5. Controller Status Setup Stage

A Hard Reset will cause the controller to re-enumerate.

In the case of a Soft Reset, after sending the command, the controller will acknowledge (ACK) the transfer, but the command will not yet be completed. Before sending any other commands, the host should poll with GetStatus until the command status field returns “Soft Reset Occurred,” “Command Complete,” or “Fail”. Any timeout for this status polling should be 2 seconds minimum.

Set Feature –Restore Defaults

This is a request to restore parameter defaults.

After sending this command, the controller will acknowledge (ACK) the transfer, but the command will not yet be completed. Before sending any other commands, the host should poll with GetStatus until the command status field returns “Command Complete” or “Fail”. Any timeout for this status polling should be 2 seconds minimum.

Asynchronous Reports

Coordinate Data – Multi-Touch Digitizer mode Async Report 0x13

This is used to transfer the coordinate data to the host. This report, when activated, is sent to the host whenever new data is available or scheduled for transmission. It is an asynchronous report that is activated by default at power up.

The report shown below supports up to 6 simultaneous touches. Note that if more than 6 touches were to be supported, Report 0x13 would be sent as many times as necessary to accommodate the number of fingers touching. Only the first Report 0x13 will have a nonzero actual count. Each valid touch is marked with an ID number that remains the same from touchdown through liftoff. The ID number can be any value from 0 to 255. Ignore all other data within a touch report structure with a status marked “not valid”.

The coordinate system is Upper Left origin.
