9.4.6. Human Machine Interface Module
The human machine interface (HMI)-related source files, called hmi.h and hmi.c, are located in the /src/driver/
folder. In order to use this module, the required handlers need to be initialized at the very beginning of the program.
The status of the various hardware components must be checked in order to have a common cyclic mechanism. In
addition, it is vital that a 1 ms interrupt-based cycle run in the background to serve the different handlers. Using the
LED handler, states of LEDs can be set and cleared either separately or together.
Using the button handler, statuses of the push-buttons can be read. If multiple button events happen
simultaneously, they can be stored to be handled later. The last pushed button event is always available first
amongst the un-handled events. Using the buzzer related sub-interface, the state of buzzer can be changed to the
required one.
