5.0 Using the Graphical User Interface (GUI)
5.1 Demonstration using the GUI
The GUI is installed during the installation process. To start the GUI click on the Motor Control Demonstration
ICON in the start menu.
Please note that for Windows Vista and Windows 7 users, it is necessary to run the GUI as “Run as
administrator”.
It is suggested that the USB cable should be connected to the PC and the board before opening the GUI as this
makes the connection process easier. The GUI can be opened without the board being connected.
It is also recommended that that there are no other peripheral devices connected to the port or hub being
used for the motor control kit.
Once the GUI is open use the following procedure to connect the GUI to the YRMCKITRL78G14 board.
If more than one “setup”file is in the GUI installation directory (C:\MCDEMO\..) then the user has to
select the appropriate “setup”file from the “Select Board Setup” drop down menu bar in the
Communication Settings box, located in top left hand corner of the GUI panel. Otherwise the default
“setup”file is selected by automatically.
Select the “setup” file (or alternative setup file name as required)
Select the “serial Port” drop down box and select the communications port that the YRMCKITRL78G14
board is connected to
Click on the “connect” button
5.2 The GUI should now be connected to the board
To start the demonstration, press the “DEMO”button in the GUI.
The board should follow the same sequence as described for the stand alone operation. (Section 3)
5.3 Manual Control of the motor

6.0 RL78/G14 Programming
The RL78/G14 can be programmed in two ways
1. Using the Renesas Flash Programmer and the E1 module (Not included in this kit).
It is generally not required to change the jumper settings on the YRMCKITRL78G14 board when using the
E1 programmer. Please refer to the user manuals included in the documentation for this kit for the correct
operation of the E1 programmer and the RFP.
2. Using the main USB interface
Please note that it is not possible to connect both the GUI and the RFP at the same time via the USB
interface. To use the RFP directly with the USB interface please set jumpers to the following the settings:
JP3, JP4, JP5, JP6 and JP7 to Pins 1 –2
The RFP should be configured to use the Serial port connection.
Please refer to the RFP user manual for the correct operation and settings
Note: the YRMCKITRL78G14 board can be programmed with an isolated USB interface when using an
external power supply and non-isolated when board is powered only by the USB interface.

7.0 RL78/G14 Debugging
As part of the installation process the IAR Embedded Workbench (Kick Start version) is installed. This allows
some additional development and testing of the motor control operation
Code development for the RL78/G14 can be made and debugged in two ways
1. Using the IAR Embedded Workbench and the E1 unit in On Chip Debug (OCD) mode.
As the E1 is not included in this kit it usage details are not included with this guide.
Please refer to E1 documentation included on the software CD and the YRMCKITRL78G14 Motor
Control Starter Kit user manual. It is possible to use the E1 debugger together with the motor control
GUI although limitations exist.
2. Using the IAR Embedded Workbench in direct mode (TK)
The IAR debugger can be used directly with the board using the “TK” setting in the Debugger options.
This utilises the same serial port and virtual UART configuration as the RFP.
Note: the IAR debugger cannot be used together with either the motor control GUI or RFP.
To use the IAR debugger set the Jumpers as follows:
JP3, JP4, JP5, JP6 and JP7 to Pins 1 –2
When the IAR CSPY debugger is activated it will connect and download (program) the built program
open in the workbench IDE. The same debugging functions are available for this mode as for the E1
OCD module.
This mode of debugging can be used with or without an external power supply as the operation of the
interface can operate as both isolated and non-isolated.
The full operation of the IAR Embedded Workbench is beyond the scope of this guide. Please refer to
the IAR documentation included with the IAR installation and the YRMCKITRL78G14 Motor Control
Starter Kit user manual.
