Function:
BOOL USB_HID_DataCollectionHandler(void)
Description:
This function is invoked by HID client , purpose is to collect the
details extracted from the report descriptor. HID client will store
information extracted from the report descriptor in data structures.
Application needs to create object for each report type it needs to
extract.
For ex: HID_DATA_DETAILS pickit.keys.modifier.details;
HID_DATA_DETAILS is defined in file usb_host_hid_appl_interface.h
Each member of the structure must be initialized inside this function.
Application interface layer provides functions :
USBHostHID_ApiFindBit()
USBHostHID_ApiFindValue()
These functions can be used to fill in the details as shown in the demo
code.
Precondition:
None
Parameters:
None
Return Values:
true - If the report details are collected successfully.
false - If the application does not find the the supported format.
Remarks:
This Function name should be entered in the USB configuration tool
in the field "Parsed Data Collection handler".
If the application does not define this function , then HID cient
assumes that Application is aware of report format of the attached
device.
