Screen Rotation Registry Settings (Windows Embedded CE 6.0)

1/6/2010

By default, the screen is oriented at a zero degree angle of rotation after downloading the run-time image to the CEPC. You can change the default angle of the screen by setting the appropriate registry key. However, any applications that subsequently run on the CEPC and rotate the screen will override the settings in the registry file.

In this procedure, you will set the registry key for screen rotation. If you do not want to change the default angle of the screen orientation, you can skip this procedure.

The following table shows the values you can use in the Angle registry subkey.

Value Description

0

No rotation.

5A

90 degrees rotated clockwise.

B4

180 degrees rotated clockwise.

10E

270 degrees rotated clockwise.

  1. In the Solution Explorer window, expand the Parameter Files branch.

  4. Save the file by choosing File and then Save, and close the file by choosing File and then Close.
