Firmware architecture

The following Figure 2 and Figure 3 show the component files.

Figure 2. Serial communication driver files

The serial communication firmware module contains the files ST7580_Serial20.c/h.They

provide FSM (finite state machine) and the functions to manage the serial data flow from

and to the ST7580 devices.

Figure 3. BSP files

The BSP firmware module contains all the definitions and the configurations of the hardware

resources used by the system to perform and manage the connection and serial

communication from the ST7580 to the STM32Fx and vice versa.
