5 Operating Modes
5.1 Overview
The Evaluation Board can work in two modes: “standalone” mode and “host” mode.
5.2 Standalone Mode
In standalone mode, no PC connection is required. Both microcontrollers are factory
programmed with the same sample application.
To run the built-in example:
1.
2.
3.
4.
5.
6.
7.
8.
The output of the potentiometer, light sensor and temperature sensor is also sent to the host
PC (if connected) through the virtual COM port over the USB connection. To see the data sent
to the virtual COM port, do the following:
1.
2.
3.
Power off the board.
Put either the MC9S08QE128 or MCF51QE128 microcontroller in the socket.
Ensure that all of the jumpers in the “I/O” sections are inserted.
Power on the board.
Press the "PTD4" push-button. The value of the ADP0/PTA0 potentiometer will be
displayed on the PTE[7..0] LEDs.
Press the "PTD5" push-button. The value of the light sensor will be displayed on the
PTE[7..0] LEDs.
Press the "PTD6" push-button. The ADP0/PTA0 potentiometer will vary the frequency of
the sound played by the buzzer.
Press the "PTD7" push-button. The value of the temperature sensor will be displayed on
the PTE[7..0] LEDs.
Ensure that the J206 jumpers (“COM1 ENA”) select the “MDI” position;
Connect the board to the PC through the USB connection;
Start your terminal utility (e.g. HyperTerminal) with these parameters:
Baud rate: 9600
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
