7.2.2 Register Settings
The registers that the sample driver uses (writes to) and their settings are defined in the file “usbf850.h.” By rewriting
these values in the file according to the actual application, you can configure the operation of the target device through
the sample driver.
(1)
File “usbf850.h”
Defines the settings of the USB function controller registers.
7.2.3 Contents of the Descriptors
The file “usbf850_desc.h” defines the data (see section 4.1.3, Descriptor Settings) that the sample driver registers in the
USB function controller during initialization processing. By rewriting these values in the file according to the actual
application, you can set up the attributes and other information of the target device through the sample driver.
Note that if the device descriptor vendor ID and product ID are modified, it will be necessary to also modify the host
driver (.inf file) used when connecting the target device in the same way. (See section 7.2.4 (3) Changing the Vendor ID
and Product ID.)
Also, arbitrary information can be registered in the string descriptor. Since manufacturer and product information are
defined in the sample driver, the user should declare and modify this information.
