3. GUI
In this chapter, GUI to control CEC of HDMI from PC (CEC Viewer) is described.
- The sample program (CEC_Sample_K0R.hex) is pre-installed on the TK-78K0R/KG3.
If you wrote other programs on the system, you can write the sample program
(CEC_Sample_K0R.hex) again by using following tools.
- Flash memory programmer for MINICUBE2 "QB-Programmer" or debugger
"ID78K0R-QB".
- This sample program works only if 20MHz oscillator is mounted on TK-78K0R/KG3.
- The remote control receiving function of this sample program (CEC_Sample_K0R.hex)
supports only NEC format.
- CEC Viewer works with Microsoft Excel. (operation check has been done on Excel 2000 and
Excel 2003)
3.1 CEC Viewer Functions
CEC Viewer has following functions.
- Monitor sending/receiving CEC data
- Send specific commands from user input
- Pre-set command data, 20 KEY
- Output log data with Excel format
- Reproducing function by loading log data with Excel format
3.2 CEC Viewer Files
File Description
CECViewer.exe Start CEC Viewer by executing this file.
command.xls
CEC command (Opcode) data file. With using this file, you can add
new Opcode.
Since the program retrieves the command data from this file, do not
close this file while CEC Viewer is running.
cecviewer.ini Pre-set key data that is registered with GUI is stored in this file.
