VESA DDC Support

    

VESA DDC Dialog

The application supports the access to VESA DDC EEPROMs that are compliant to the standard VESA E-EDID 1.3.

The access to VESA DDC EEPROMs can be traced. A plug-in is available for this purpose.

telos offers a cable to get access to the special data lines inside the VGA cable and make them available for control and measuring purposes. This is quite helpful for using the Tracii XL analysing and maintaining this information.

When the menu item 'Tools/VESA DDC' is selected, a dialog is displayed that allows for reading, manipulating and writing the information stored in a VESA DDC EEPROM.

These EEPROMs must have a capacity of 128 bytes and must be assigned to address 0x50.

VESA DDC Dialog

Writing the EEPROM

  • Select the board, which is connected to the desired I2C bus.
  • Press the button 'Write'.
  • A dialog shows up. Commit the intention to change the content of the EEPROM by pressing the button 'OK'.
  • The data is sent to the EEPROM.

Reading the EEPROM

  • Select the board, which is connected to the desired I2C bus.
  • Press the button 'Read'.
  • The data is read from the EEPROM and displayed in the VESA DDC Dialog.

Data Export

The content of the data in the dialog can be exported into a binary file by pressing the button 'Export'.

Data Import

The content of an export file can be imported by pressing the button 'Import'. The data is shown in the VESA DDC Dialog. After that, the data can be sent to an EEPROM.
