HAL layer firmware overview
The following section describes the hardware abstraction layer function used by the upper
API layer described in the previous section. All the library microcontroller hardware
dependent functions and related defined types are described in this section. See Figure 14,
15, 16.
The final application should never directly use these HAL functions, and it should only
manage LCD, touchscreen, and joystick through API layer functions as described above.
