i2c SCL shows a DC offset in the waveform

Hi,

I am getting a strange problem while using atmega328 i2c to connect my apds9960 gesture sensor. I have connected the SDA and SCL of apds9960 using 2.2k pull-up to my atmega. The SDA works fine and the waveform generated is as expected, however, the SCL waveform shows a DC offset of 0.3-0.4V.

Also, my sensor works quite well for sometime, however the i2c hangs after sometime. I am not sure if the problem is because of the dc offset. Any help would be appreciated.

Regards

Please post the schemata for this setup. And also provide information about how you power your ATmega.
