4.12 Overall Block Diagrams

The processes and components discussed in the previous sections come together to implement the HOGP project. Figure 4-10 shows the process in which the report map is shared with the HID Host device.

As shown in Figure 4-10, the report map is provided to the HID Host shortly after the connection is established. After the report map is provided to the HID Host, the Host will save it and use it to interpret any future notifications sent by the HID Device.

Figure 4-11 shows how the HOGP project, acting as an HID Device, transmits HID inputs to the HID Host.
