17. IAR Embedded Workbench Usage
The following section how to set up and use the IAR Embedded Workbench with the YRMCKITRL78G14 motor
control kit. Before connecting the USB cable to the board and the PC, ensure that the jumpers are set as below
Jumpers JP3, JP4, JP5, JP6 and JP7 Pins 1–2 connected
Jumper JP1 and JP2 can be connected either as 1-3 or 4-6
Please note
1. If an external power supply is used JP1 and JP2 should both be set to position 1-3 which isolates the
USB interface, so that it is safe to connect to the PC
2. The IAR Embedded Workbench needs to have been registered and the license installed before it can
be used. The RL78/G14 motor control project included with this kit is designed to be compatible with
IAR Embedded Workbench version 1.20 or later. The IAR installation should be installed as the
“kickstart” version which needs to be registered with IAR. Please follow the installation and licensing
instructions from the IAR installer and documentation.
3. It is not possible to run both the control GUI and the IAR debugger at the same time as they both use
the same virtual UART USB interface. To run the debugger and the GUI it is necessary to use the E1
connector for the RL78/G14.
Care should be taken when using a high voltage external power supply as the E1 interface
is not isolated.
Please make sure that the USB cable is plugged into the PC and that the board is connected.
The IAR Embedded Workbench will have been installed in the default or user location
The default location is as follows
Start Menu =>
All programs =>
IAR Systems =>
IAR Embedded Workbench for Renesas RL78 1.20 =>
IAR Embedded Workbench.exe
Double click on the file to open. (Note that Windows Vista and 7 users may have to use “Run as administrator”) and the
opening screen should open as below.
Please see section for the option detail to permanently enable “Run as administrator”
