  • Page 17: Microtouch™ Ex Serial Controller Communications

    3M™ MicroTouch™ EX Serial Controller Communications This chapter discusses the fundamentals of communicating with the 3M™ MicroTouch™ EX serial controller. The firmware commands, which are usually issued by a driver or utility program on the host system, control the operation of the touch controller, however developers can enter these commands directly.

  • Page 18: Controller Default Settings

    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 19 3M™ MicroTouch™ Controller EX Serial Reference Guide The commands listed in the following table are those that 3M Touch Systems currently uses for development. 3M Touch Systems recommends that you use only these commands for 3M™ MicroTouch™ EX serial controller development.

  • Page 20: Firmware Commands

    Reset command also cancels the Format Raw, Calibrate Raw, and Calibrate Extended commands and returns the controller to normal operation. 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.

  • Page 31: Restore Defaults

    Description: Returns to the factory default operating parameters. The Restore Defaults command copies the 3M Touch Systems factory default parameters from ROM to the non-volatile memory (NOVRAM) and then executes a Reset command. Table 12 lists the factory defaults for the EX serial controller. The Restore Defaults command is useful in situations where inadvertent commands to the controller have rendered the sensor inoperative.
