| void * | coffeeThread (void *threadid) |
| Thread for the finite state machine It represents the current state of the machine and handles signals coming from the pressure control, buttons, the brew switch and the proximity sensor. More... | |
| void | coffeeHandler (int signum, siginfo_t *siginfo, void *context) |
| Handler for the Signal send to this thread It saves the type of signal received and tracks the time between a push and release event of up to 4 signals The time is stored in the HalEvent variable when a release event is received. More... | |
| int | getSigValue (void) |
| returns the Signal value from the last received Signal and clears the variable More... | |
| bool | SigValueEmpty (void) |
| void | changeState (int newState) |
| Changes the state of the machine to newState prints the change to the logger. More... | |
| int | getState (void) |
| Returns the current state of the FSM. More... | |
| void | brewTimeHandler (void) |
| Counter for the brew time refresh every 200ms. More... | |
| void | coffeeTerminate (void) |
| handles program termination More... | |
| void | coffeeBrew (void) |
| Brewing process. More... | |
