4.5.6 State—Sending results<br />
Once the end of exhalation is detected, the next state is the sending results state. It consists of filling the results buffer <strong>with</strong><br />
the final results obtained <strong>with</strong> the calculation routines, and generates an event to send that information to the computer.<br />
Afterwards, the measurement is aborted by stopping the timer, changing the state to idle, and turning the MED-SPI board off.<br />
Figure 20 shows the flow chart.<br />
