ADPD188BI

Hello . As there is something with the board I made , I cant work it out . So I bought EVAL-ADPD188BIZ-S2 from you .

I'm trying to use it ,but I still got some questions .

As shown in the sheet (《EVAL-ADPD188BIZ-S2 User Guide》)。I connect I2C_SCL and I2C_SDA, 1.8V voltage,GND to my STM32 board. I connect MOSI SCLK

to the GND and CS to 1.8V .Then I generate I2C waveform ,the waveform is wrong . Is there anything wrong with my connections? If so ,please tell me .If not ,I will

explain more details on the waveform I got . Thanks !
