3M™ MicroTouch™ Controller EX Serial Reference Guide
Calibrate Extended
Syntax:
To optimize the performance of the touch controller and simplify the development of
custom drivers, 3M Touch Systems recommends you use the commands listed in Table 5
for current development. Using these commands ensures compatibility with all 3M™
MicroTouch™ controllers.
Note: When you enter commands in terminal mode, precede each command with
<CTRL> A to enter the start of header.
Table 5 Firmware Commands for EX Serial Controller Development
<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 2- or 4-point calibration in 3M™ MicroTouch™ Software.

Description
Initiates an interactive 2-point calibration.
Collects the raw X and Y coordinates before normal scaling,
linearization, and filtering process.
Returns the signal level (amount of touch) of each of the four
sensor corners in digital format.
Outputs the X/Y touch coordinate data in a five-byte packet.
Preferred for current development.
Sends a continuous stream of X/Y coordinate data when you
touch the sensor.
Returns a controller identifier string.
Queries the controller and waits for a response.
Identifies the controller type and the firmware version.
Lets you adjust the communication parameters (parity, data
bits, and stop bits) of the controller.
Initializes the hardware and the firmware, causes the controller
to stop sending data, and recalculates the environmental
conditions.
Returns the controller to the factory default operating
parameters. Note: the serial port is reset to N81 format tablet
and 2-point calibration is lost.
Identifies the touch controller on your system.
