Using the Blood Pressure Monitor

When a user plugs in the blood pressure monitor, a splash screen with the Freescale logo will appear. The

logo will scroll in from the right, and after it reaches the center scroll down and leave the OLED display.

While this is happening, the pressure sensor stabilizes and auto-calibrates itself according to the

atmospheric pressure. After the splash screen has exited, a home screen will appear. Here the user is able

to navigate and use the blood pressure monitor demo.

Navigation

The home screen contains an icon of a heart with the word “Start” under it, and an icon of a folder, with a

hammer and screwdriver, that has the word “Options” under it. Whichever item is selected will have a

larger size than the other, and the words under the image will appear inside a yellow box, resembling a

highlight. This highlighting is used on all screens to indicate a selected item.

Figure 2-2. Home Screen with Start Selected

Movement within the options can be done by pressing the buttons on the board. The left and right buttons

switch between the Start and Options items, and the center button acts as an enter button.

If the user selects the start option, the device will begin taking a blood pressure measurement.
