Reprogram the MCU
using CodeWarrior
Development Studio
Import the downloaded reference design
application project in the CodeWarrior
Development Studio:
1. Start the CodeWarrior application.
2. Click File – Import.
3. Select General – Existing Projects
into Workspace.
4. Select “Select root directory” and
click Browse.
5. Navigate to the extracted application
directory: KEA128LEDLIGHTRD/
KEA128_LIGHTING_RD and click OK.
6. Click Finish.
7. Click Run>Debug to download the
code to the KEA128. This starts the
launching progress until the debugger
perspective appears and stops at the
line of main () in the source view. Click
on the stop button.
FreeMASTER
Setup

Application Control in FreeMASTER
The FreeMASTER run-time debugging tool is used to control the application and
monitor application variables during run-time. An explanation on how to use the
FreeMASTER user interface is given below.
1. Click the Output Control button in the Output Channel section or press
switch SW2, SW3, SW4, SW5 to control each output state. The output states
are OFF, ON or TOGGLE.
2. To change the PWM duty cycle of the outputs using only the FreeMASTER
sliders, click in the FreeMASTER PWM Control button located in the General
Settings section. Button must be in ON state. When button state is OFF the
duty cycle of the outputs can be controlled only using the potentiometers R18,
R89, R90, and R91.
3. Change the PWM duty cycle of the outputs by moving the PWM Duty Cycle
slider of each output.
4. In case of an output fault, the corresponding fault label will turn red in the
Diagnostic and Status Flags section of each output.
5. General faults flags and operation mode of the system are indicated in the
General Settings section. By default the operation mode is Normal Mode.
6. In case of an under voltage fault, stop the FreeMASTER communication by
clicking the red STOP button. Remove the under voltage condition. Start the
FreeMASTER communication by clicking the red STOP button. The Fault
Status and the Under Voltage label will turn red and the outputs will be off.
To remove this fault click on the Clear Under Voltage Fault button or press
any switch SW2, SW3, SW4, SW5 on the board, to return the system to its
Normal Mode.
