MED-SPI

Freescale Tower System

The MED-SPI plug-in board is compatible with the Freescale

Tower System, a modular development platform that enables rapid

prototyping and tool re-use through reconfigurable hardware. Elevate

your design to the next level with this industrial powerhouse by

building your Tower System today.

MPXV7025DP Differential

Pressure Sensor

MED-SPI is a development board which demonstrates

the basic implementation of a spirometry application.

It includes the MPXV7025DP differential pressure

sensor, which allows calibrated pressure and air flow

measurements ideal for medical respiratory monitoring

devices.

Quick Start Guide

Verify the Jumper

Configuration

Verify the jumper configuration on

each board according to the Jumper

Configurations table found later in this

guide.

Assemble the

Tower System

Assemble the Tower System by matching

primary and secondary sides on the

serial and MCU boards to corresponding

elevators.

Step-by-Step Installation Instructions

In this quick start guide, you will learn how to set up the MED-SPI and Tower System

and run the included demonstrated software. For more detailed infomation, review the

user manual at freescale.com/healthcare.

Connect the

MED-SPI AFE

Connect the MED-SPI AFE to the medical

connector on TWR-K53N512. Board

must be placed as shown below.

Note: MED-SPI board must be plugged to the

medical connector before the Tower System gets

powered

Download and

Install Software

Download and install IAR Embedded

Workbench 6 for ARM

. A 30-day

trial version can be downloaded from

iar.com.

TOWER SYSTEM

Install the

Drivers

Install P&E Micro drivers. The installer

is located in IAR installation folder\arm\

drivers\pemicro.

Connect a

USB Cable

Connect a USB cable from the computer

to the USB port on the TWR-K53N512

board. Wait for drivers to install.

Download the

Application Note

Go to freescale.com and conduct a

parametric search for AN4325. Download

AN4325SW.zip.

Open the

File

Open the file MED-SPI K53.eww using

IAR from \Software\MED-SPI_K53\app\

cdc\iar_ew\kinetis.

Load the

Firmware

Click the Debug button to load the

firmware to the MCU.

Step-by-Step Installation Instructions

Continued

Install the

Software

Install the Medical GUI software. It can

be downloaded from freescale.com.

Note: Make sure you have already installed Java®

JDK on your computer. Look for JDK folder in:

C:\Program Files\Java

Change the

Connection

Disconnect the USB cable from the

TWR-K53N512 and connect it to the

TWR-SER board.

Look for the

COM Number

In the device manager, look for the COM

number assigned to “Virtual Com Port.”

Open the

Medical GUI

Open the Medical GUI and select the

Virtual Com Port from previous step.

Install Drivers for

JM CDC Demo

If the driver is not installed automatically,

open Device Manager and install drivers

for JM CDC Demo. Drivers can be

found here:

• 32-bit version:

C:\Freescale\Medical GUI\Drivers\x32

• 64-bit version:

C:\Freescale\Medical GUI\Drivers\x64

Note: Open the Device Manager by opening

the start menu, right-clicking on Computer and

selecting Manage. Device manager is on the

left options tree.

TOWER SYSTEM

Quick Start Guide

Breathe

into the Tube

In the main window, click the SPI section

(pink) and follow the next steps:

1. Place the tube in your mouth

2. Inhale as much air as you can.

3. Without taking the tube out of your

mouth exhale as hard and fast as

possible.

4. Click again on the SPI section.

Attach

the Hose

Attach the hose to both the mouthpiece

and the pressure sensor as shown in the

image below.
