Configuration

There are several issues to consider when configuring the display driver. The issues cover debugging support, register initialization values and memory allocation. Each of these issues is discussed in the following sections.

Compile Switches

There are several switches, specific to the S1D13705 display driver, which affect the display driver.

The switches are added or removed from the compile options in the file SOURCES.

WINCEVER

This option is automatically set to the numerical version of WinCE for version 2.12 or later. If the environment variable, _WINCEOSVER is not defined, then WINCEVER will default 2.11. The display driver may test against this option to support different WinCE version-specific features.

DEBUG_MONITOR

This option enables the use of the debug monitor. The debug monitor can be invoked when the display driver is first loaded and can be used to view registers, and perform a few debugging tasks. The debug monitor is still under development and is untested.

This option should remain disabled unless you are performing specific debugging tasks that require the debug monitor.

TEST_BITMAP

This option allows the debug monitor to display a test bitmap. This bitmap is big and will make the display driver considerably larger. The flag DEBUG_MONITOR must also be enabled for this option to work.

This option should be disabled unless the image is required for debugging.
