Figure 9-2 General Architecture Between a Host and HID Class
The host operating system (OS) enumerates the device using the control endpoints. Once
the enumeration phase is done, the host starts the transmission/reception of reports to/from
the device using the interrupt endpoints.
On the device side, the HID class interacts with an OS layer specific to this class. The HID
OS layer provides specific OS services needed for the internal functioning of the HID class.
This layer does not assume a particular OS. By default, Micriμm provides the HID OS layer
for μC/OS-II and μC/OS-III. If you need to port the HID class to your own OS, refer to
section 9-5 “Porting the HID Class to a RTOS” on page 160 for more details about the HID
OS layer.
During the HID class initialization phase, a report parser module is used to validate the
report provided by the application. If any error is detected during the report validation, the
initialization will fail.
