3. Demonstration program operation (Cont)

14. If a value between 1 and 7 was selected from

the main menu, then the user must next

select the CPU load option with the

potentiometer and SW1 in the same way.

Upon selection with SW1, LED1 will flash the

appropriate number of times to confirm the

selected value:

15. The MCU now enters a full power loop in the selected mode. Current measurements can be taken across J6

at this point. Note that changing the ammeter range may interrupt the power to the CPU, causing a reset or

strange behaviour.

16. Pressing SW1 will put the CPU into the selected low power mode and again current measurements can be

taken across J6.

17. To exit the low power mode and restart, press the RES1 switch.

4. Debugger operation and the HEW Workspace

Once you have tested the pre-programmed demonstration, it is time to connect to the board and write some code.

High-performance Embedded Workshop (HEW) integrates various tools such as compiler, assembler, debugger

and editor into a common graphical user interface.

The workspace supplied is set to automatically connect to the on-board Segger J-Link debugger circuit (located on

the underside of the RPB).

18. To program or debug, you must enable the debugger circuit by removing J15.

19. Connect the RPB's underside USB connector to a spare USB socket on the PC.

20. Note that the first time it is connected here, J-Link will install its driver automatically.

Note: Windows Vista users may need to enter an administrator password during this process.

21. Launch HEW from the Start Menu. (Start Menu > All Programs > Renesas > High-performance Embedded

Workshop).

22. In the "Welcome" dialog box select "Create a new project workspace". Click <OK>
