8.2 Developing a Driver Using the Enhanced Chipset Support
When developing a driver for a device based on one of the enhanced-support
chipsets [
8.1], you can use WinDriver's
chipset-set specific support by following these steps:
-
Locate the sample diagnostics program for your device under the
WinDriver/chip_vendor/chip_name/ directory.
Most of the sample diagnostics program names are derived from the
sample's main purpose (e.g.
download_sample for a firmware download
sample) and their source code can be found directly under the specific
chip_name/ directory.
-
Run the custom diagnostics program to diagnose your device and familiarize
yourself with the options provided by the sample program.
-
Use the source code of the diagnostics program as your skeletal device
driver and modify the code, as needed, to suit your specific development
needs. When modifying the code, you can utilize the custom WinDriver API for
your specific chip. The custom API is typically found under the
WinDriver/chip_vendor/lib/ directory.
