3M™ Multi-touch Display M2256PW User Guide 21 APPENDIX A 3M™ PX USB Controller Communications This appendix is intended for software developers only and discusses the fundamentals of communicating with the 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 Display M2256PW User Guide synchronous report in response to some of these requests. You need to know product ID (0502H) 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.

3M™ Multi-touch Display M2256PW User Guide 29 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 Display M2256PW User Guide Controller Default Settings Communication Parameters The operation of the PX serial controllers is N81 (no parity, 8 data bits, and 1 stop bits) at 115,200 baud (nonadjustable). 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 Multitouch is the default format for the 3M™ PX serial controller.
3M™ Multi-touch Display M2256PW User Guide 31 Sending Commands to the Controller When you send a command to the controller, you must use the correct command format. The general format of a command is as follows: Command Note: The following descriptions of header, command, and terminator, use 3M Touch Systems terminal emulator key sequences. You may need to enter the sequence in a different format, depending on your emulator.
3M™ Multi-touch Display M2256PW User Guide The command response, which always follows the header, is a range of ASCII characters depending on the type of command sent. Responses can be in many forms. For example, one standard response is 0 (ASCII character ‘zero’ or 30 hexadecimal). This response indicates a successful command completion for most commands, while it indicates a failed completion for other commands.
3M™ Multi-touch Display M2256PW User Guide 33 Note: When you enter commands in terminal mode, precede each command with A to enter the start of header. Table 17. Firmware Commands for PX Serial Controller Development Command Calibrate Get Copyright Mode Down Up Mode Inactive Mode Stream Name Null Command Output Identity Reset Restore Defaults Unit Type Code CX Q101 MDU MI MS NM Z OI R RD UT Description Initiates an interactive 2-point calibration. Returns the copyright string.
3M™ Multi-touch Display M2256PW User Guide Calibrate Procedure To use the CX command: 1. Enter the Calibrate (CX) command. The controller sends an initial acknowledgment of 0. 2. Touch the sensor at a lower left target, which is located 12.5% (1/8) in from the corner of the video image. The controller returns an acknowledgment of 1. This is a positive response.
3M™ Multi-touch Display M2256PW User Guide 35 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 that the touch screen coordinates for the serial interface have their origin in the lower-left corner.
Description: 3M™ Multi-touch Display M2256PW User Guide This is the default mode of operation at power up. Touch reports include touchdown and liftoff events as well as continuing touches. Name Command Syntax: NM Response: 0 Positive response. Description: Returns a name string Null Command Syntax: Z Response: 0 Positive response. Description: Queries the controller and waits for a response.
3M™ Multi-touch Display M2256PW User Guide 37 3M Touch Systems recommends that the host system issue a Reset command whenever the host system is powered on and is attempting to establish communication with the controller. The amount of time needed to execute a Reset command is typically 500 milliseconds with a defined maximum of 2000 milliseconds.
3M™ Multi-touch Display M2256PW User Guide AD Ffff = Four ASCII characters that indicate the features supported by the controller. **** Ss Indicates the PX series of controllers Indicates no additional features configured = Two ASCII characters that provide status information about the controller hardware. The two characters represent one byte. Each character is in the range 0 to 9 and A to F. Table 2 defines the meaning of each bit in the status byte.
3M™ Multi-touch Display M2256PW User Guide Data Sequence Bits Y - Byte 5 ID – Byte 6 7 0 0 39 6 Y13 N6 5 Y12 N5 4 Y11 N4 3 Y10 N3 2 Y9 N2 1 Y8 N1 0 Y7 N0 Note 1: P is the proximity bit. It is set to 1 when there is a touch, 0 for a liftoff. The ID is associated with a touch stream from one finger. The ID, in the range of 0-127, is assigned on a rotating basis at touchdown. A finger touch stream consists of a touchdown, maybe some continuing touch points, ending with a liftoff.
