DS90UB947-Q1: I2C question

Part Number: DS90UB947-Q1

Hi Team,

We found a very strange issue now, sometimes other I2C device will send some messages to I2C bus which the message address is 0x00.

In this time, the tft panel display will  disorder.

So we want to know whether 947 will action these messages(Address is 0x00)?

If 947 will action these messages, how we can stop 947 to action them?

Best Regard.

    Hi Yao,

    Can you clarify what is happening? In order to talk to our devices you need to the address of the device for example, 0x18. If you type in 0x00 to talk to our device the device will not respond because its not the chips address.

    Best Regards,
