There may be times when you choose to write your driver directly, without using DriverWizard. In such cases, either follow the steps outlined in this section to create a new driver project, or use one of the WinDriver samples, which most closely resembles your target driver, and modify the sample to suit your specific requirements.
Include the relevant WinDriver header files in your driver project.
All header files are found under the WinDriver/include directory.
All WinDriver projects require the windrvr.h
When using the
WDU_xxx WinDriver USB API [B.2], include the
wdu_lib.h header file; (this file already
Include any other header file that provides APIs that you wish to use from your code (e.g., files from the WinDriver/samples/shared directory, which provide convenient diagnostics functions.)
You can also include the library's source files in your project instead of linking the project with the library. The C source files are located under the WinDriver/src/wdapi directory.
When linking your project with the WDAPI library/shared object, you will need to
distribute this binary with your driver.|
For Windows, get wdapi1021.dll / wdapi1021_32.dll (for 32-bit applications targeted at 64-bit platforms) from the WinDriver\redist directory.
For Linux, get libwdapi1021.so / libwdapi1021_32.so (for 32-bit applications targeted at 64-bit platforms) from the WinDriver/lib directory.
Note: On Windows and Linux, when using the DLL/shared object file
for 32-bit applications on 64-bit platforms
libwdapi1021_32.so), rename the
copy of the file in the distribution package, by removing the
_32 portion [A.2].
For detailed distribution instructions, refer to Chapter 11.
WDU_Init() [B.4.1] at the beginning of your program to initialize WinDriver for your USB device, and wait for the device-attach callback. The relevant device information will be provided in the attach callback.
WDU_Transfer() [B.4.8.1] functions family to send and receive data.
WDU_Uninit() [B.4.7] to unregister from the device.
After including the required files and writing your code, make sure that the required build flags and environment variables are set, then build your code.
Before building your code, verify that the |
On Windows, Windows CE, and Linux you can define the
