Read Calibration Point Test (Compact 2013)
3/26/2014
The Read Calibration Point Test tests the TouchPanelReadCalibrationPoint function, which reads a single point of data from the touch panel. This test requires you to firmly touch and release the screen once during the test. The test prompts you when this action is necessary. This test fails if the TouchPanelReadCailbrationPoint function call fails.
This is test 1004 of the touchfunc.dll test suite.
Failure may occur if the function is implemented incorrectly, if the touch-panel driver fails to recognize the touching of the touch panel as calibration data, or if you fail to touch the panel when prompted. This test is skipped if the touch-panel driver does not export a TouchPanelReadCalibrationPoint or TouchPanelReadCalibrationAbort function.
Note: This touch-panel driver-level test requires user interaction using a touch pen on the touch panel for most tests. After the test is complete, the OS loses control of the touch panel. Download a new image before running any more tests.

Running the Test
This test requires that you interact with the touch panel. You must follow the instructions on the display to run the test correctly. When the test prompts you, you must perform the requested action. If you do not complete the action, the test times out and fails. The test times out after approximately 15 seconds.
The default command line is:
tux -o -n -d touchfunc -x1004
Verifying the Test
In some cases, the test requires that you select Yes or No in response to a question. To respond, you must tap the part of the touch panel that contains the appropriate response.
Troubleshooting the Test
When you complete the test, the operating system does not regain control of the touch panel. You must reset the touch panel to restore usual operation.
