I2C Functions

This section contains reference pages for the I2C callback functions, which must be implemented by any video miniport driver that calls the video port driver's VideoPortDDCMonitorHelper function.

VideoPortDDCMonitorHelper implements the details of reading a monitor's extended display identification data (EDID) according to the I2C specification, but must rely on the following functions, implemented by the video miniport driver, to read and write individual data bits to the I2C serial clock and serial data lines:

ReadClockLine

ReadDataLine

WriteClockLine
