Exercise-003 Implementing initial transition actions

 

 

Implementing initial transition actions
Figure 1. Protimer_init function

 

The protimer_init function is an initial transition function. It is making a transition to IDLE state. But the IDLE state has its Entry action, the Entry activities there, that’s why, whenever you set the state as IDLE here, you have to call its ENTRY action.

Create one temporary variable, event_t ee; event entry action. 

And ee.sig = ENTRY; and you have to call protimer_state_machine. Because you have to send the entry event to the IDLE state. ‘mobj’ and send the address of the ee variable, as shown in Figure 1. This function is used only one time.
