DRM101 Datasheet, PDF (15/56 Pages) Freescale Semiconductor, Inc – Blood Pressure Monitor Using the Flexis QE128 Family

Introduction
2.4 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.
2.5 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.

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.
