Page 19: Calibration Request 4
Because Report 1 sends touch data continually, it is the most versatile mode, and it provides the best response time and overall feel. 3M Touch Systems recommends that the touch driver generate an event 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. -

3M™ MicroTouch™ Controller EX Dual Mode Reference Guide Response The device stalls endpoint 0 if the request cannot be processed successfully. The host should issue status requests to determine the status of this request. A command status of 1 indicates that the controller is waiting for a touch in the lower left quadrant. A status of 2 indicates that the lower left touch has been completed and the controller is waiting for a touch in the upper right quadrant. -

Page 23: Reset Request 7
3M™ MicroTouch™ Controller EX Dual Mode Reference Guide Reset Request 7 This is a request to perform a controller reset. The standard hard or soft reset can be requested. Soft resets are generally required for any parameter changes to take effect. A soft reset results in the touch application using its initial (start-up) values. -
Page 24: Restore Defaults Request 8
The hard reset did not use a device disconnect as part of the reset process for the previous 3M™ MicroTouch™ USB controller. The disconnect causes the driver to unload and will result in any handles to the driver that an application may have becoming invalid. An application should handle an unplug event. -

Data format refers to the type of packet the controller uses to send the X/Y touch coordinates to the host system. Format Tablet is the default format for the 3M™ MicroTouch™ EX serial controller. In Format Tablet, the controller sends 5 bytes per point and provides the most rapid response time to a touch. - Page 31 The general format of a command is as follows: <Header>Command<Terminator> 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.

Page 33: Calibrate Extended
Identifies the touch controller on your system. Calibrate Extended Syntax: <SOH>CX<CR> Note: This command should not be used when 3M™ MicroTouch™ Software is being used. The CX command will interfere with the auto orientation algorithm. To calibrate, use the calibration routine in 3M™ MicroTouch™ Software. Description: Initiates an interactive 2-point calibration. - Page 34 3M™ MicroTouch™ Controller EX Dual Mode Reference Guide • The controller uses the data immediately before liftoff to register a calibration touch. Therefore, you can touch the sensor, move your finger to the target, hold for a few seconds, and then lift off. Instructing users to touch this way results in a more accurate calibration.
