The device driver source code is separated into hardware platform dependent code, chip support package (CSP) drivers, and common drivers. With this directory structure, you can copy a public driver to your %_TGTPLAT% directory, and then optimize and test the driver. For information about developing a BSP, see How to Create a Board Support Package. For information on testing drivers, see How to Use the CETK to Test a Driver.

The following table shows the location of the device driver source code.

PathDescription
%_WINCEROOT%\Platform\%_TGTPLAT%Contains hardware platform dependent code. This directory primarily contains the OAL, configuration files, and BSP drivers. You should not have to modify the hardware platform dependent drivers in %_WINCEROOT%\Platform\%_TGTPLAT%\Drivers.
%_WINCEROOT%\Public\Common\OAK\CSPContains CSP drivers for high-integration microprocessors or microprocessor companions with many native peripherals integrated onto the microprocessor. CSP drivers include microprocessor-specific OAL drivers for real-time clocks, timers, debug Ethernet cards, and so on. Standard development boards (SDBs) with the same microprocessors can use the same set of CSP drivers.
%_WINCEROOT%\Public\Common\OAK\DriversContains common drivers for non-native peripherals, which are devices that exist on a plug-in card or are wired directly to a circuit board. Common drivers contain platform-independent code that links to the platform-dependent code to create a hardware driver. Common drivers are not specific to a hardware platform or microprocessor. Any SDB can use common drivers.
