Hi All,

 

I am testing the customized board of ADT7420uCPZ(#1440)

No response from the chip. Signal from the controller reaches the chip(I2C clock and data). But no reply.

 

Any idea how to check the chip.

 

This is all I tried.

  • In order to ensure that the problem is not from the controller/wire connection, I have test it with PMOD version
  • Checked the leads and voltages while execution. SCL and SDA are at same voltage level.
  • Design follows the pull-up for both SCL and SDA
  • Continuity test of board matches with PMOD

 

Kindly let me know the suggestion.

 

Appreciate any assistance.

 

Regards,

Santhosh Jois
