TDA8029 I2C Communication Problem

mfyasar111 — Mon, 10 Dec 2018 11:52:48 GMT

Hello ,

We want to design a product using TDA8029.

We have no problem while we try UART Communication with the IC but we can't get any acknowledge when we try to use I2C protocol.

We tried all of the possible scenarios which is written in the datasheet.I also checked the mask number of IC.

I attached a scope view of SDA and SCL lines.

Do you have any advices for us ?

Thank you.

CH2 is SDA , CH3 is SCL.
