Not receiving ACK from AIS328DQ

Question asked by Rakesh Sambrani on Dec 5, 2017

Hello Everybody,

I am trying to interface AIS328DQ with PIC32MX using I2C. I am not receiving ACK from AIS328DQ. I have used the same i2c software for other device it works fine! 


I have not used any external pull-up register for SDO and SCLK. CS pin of AIS328DQ is connected to 3.3V.  INT_1 and INT_2 are not connected. 


I have attached code below.

Please help. 


Thank you
