5 Operating Modes
5.1 Overview
The Demonstration Board can work in two modes: “standalone” mode and “host” mode.
5.2 Standalone Mode
In standalone mode, no PC connection is required. The microcontroller is factory programmed
with a sample application.
To run the built-in example:
5.3 Host Mode
In host mode the program execution is controlled by the host PC through the “USB” connector.
You can use the PC to debug the application by, for example, executing the program step by
step and watching how the microcontroller registers vary, using the provided CodeWarrior
Development Studio.
Ensure that the “OSC ENA”, “PTD5 ENA”, “PTD4 ENA”, “PTD3 ENA”, “PTA1 ENA” and
“PTA0 ENA” jumpers are inserted.
Ensure that all of the accelerometer enable jumpers (“PDT2”, “PTD1”, “PTD0”, “PTA7”,
“PTA5” and “PTA4”) are inserted.
Power on the Demonstration Board through either the 12 V DC plug-in power supply or
the 28-pin I/O Header connector, and make sure that the “POWER SEL1” and “POWER
SEL2” jumpers select the appropriate power source (see chapter “4.2 Power Supply” for
details).
The green “POWER” LED on the board should turn on.
Press the “SW0” push-button. Then, by rotating the potentiometer, you affect the results
of the A/D conversion, which in turn varies the blinking frequency of the “LED1” and
“LED2” LEDs.
Press the “SW1” push-button. Then, by rotating the board around its x, y or z axes, you
affect the accelerometer reading along that axis, and the “LED1” and “LED2” LEDs turn
on, off or blink depending on the board’s position.
