Accelerometer Demonstration
The Accelerometer Demonstration application shows various uses of the Freescale X, Y, and Z axes
accelerometers.
When using the 13226-SRB, the Accelerometer Demonstration application
is not supported because the 13226-SRB does not have an accelerometer. If
users select and export this application in BeeKit, the results will not be
accurate.
4.1
Loading the Accelerometer Application
1. Flash the Accelerometer Demonstration into two boards. One board must be either a MC1322X
Sensor Node (also compatible with 13192-SARD or MC13213-SRB) to provide the X, Y, and Z
axes accelerometer data and the other board must have an available UART and be able to connect
to a PC. This example uses two MC1322x Sensor Node boards.
2. If users need to run the Accelerometer on different targets, those projects must be generated by
BeeKit as described in
3. Download the appropriate target image by following the procedure in
Applications Into a Board Using the JTAG J-Link ARM
4.2
Board Setup
To setup both boards for operation (transmit and receive), perform the steps shown in this section.
4.3
Board One Setup (PC_Radio Board)
1. Connect a Sensor Node Board to the PC using the USB cable included in the kit. (Do not use a hub.)
2. Power on the board by setting the Power Switch to the ON position.
3. Press the Reset Button once. The LEDs are off, but the PC_Radio application is running and in
receive mode.
4.4
Board Two Setup (Accelerometer Board)
1. Connect 9 VDC power to DC power connector with the 9 VDC wall transformer included in the
kit. Power on the board by setting the Power Switch (S100) to the ON position. Another board
power option is to use the batteries which provides the advantage of true wireless operation (no
cables) and allows users to easily move and manipulate the SRB.
2. Press the Reset Button once.
