My customer system will be designed with ADI HDMI Tx.
In their system when not using HDMI Tx, SDA of I2C will be always Hi even if SCL are working by MCU as bellow.
Do any troubles occur in this case with ADI HDMI Tx?
What part are you using?
As long as you specifically do not address the TX then it should have not any effect on TX operation. We run multiple TX on one I2C bus all the time.
My customer has already tried this I2C-bus beavior with ADI HDMI Tx.
But sometimes HDMI Tx registers could not be written after repeating power-supplying over and over again.
Should SCL be high as well as SDA when not using HDMI Tx? Or should we doubt any other cause?
