About HDMI CEC
High-Definition Media Interface (HDMI) incorporates a single-wire interface called Consumer Electronics
Control (CEC) in order to support 'one touch' control features in newer audio/visual systems.
CEC is not a conventional bus and is not readily found on microcontrollers like the more common protocols I2C or SPI.
Currently TI is emulating this interface using GPIO.
Has anyone tried to emulate this interface using GPIO?
