How to add a new driver under Wince7

To add a new driver in Wince7: (Take a simple led driver as an example)

1 . Right-click the Platform\zynq7000\src\drivers directory in the Solution Explorer window and select Add->new Sources subproject, In the pop-Up Subproject wizard dialog box, select the WCE dynamic-link Library and set the subproject name to the LED. Click Next and select an empty subproject, click Next and select Add to the current Dirs file. This allows you to create a new LED driver directory under the drivers directory.

2 . In the Solution Explorer window, you can see the newly created led catalog, under which the Include files and source files directories can be added to the header files and sources. Here, add the led.h and LED.C files separately. As shown below:

LIBRARY ledexportsLed_initLed_deinitLed_openLed_closeLed_powerupLed_powerdownLed_iocontrol

5. Create a new registry file Led.reg in the LED directory and enter the following code:

[hkey_local_machine\drivers\builtin\led]"Prefix" = "LED""Dll" = "Led.dll""Order" = "1"

6 . Add the Platform.bib file modules area in the parameter files directory

Led.dll $ (_flatreleasedir) \led.dll NK SHK
