With regards ADUC7023 i2C no ACK and Stop

kabekami
on Aug 6, 2019

Hi , 

We are using ADUC7023 , when we reduce the temperature we see that master doesn't not issues clocks for ACK and STOP . 

We are using internal clock to run ADUC7023 , Clock input pin is grounded . 

If the Ground has 60-70mV will we have such problems . 

We have pulled the SCL and SDA pin with 4.7k .

Thanking you 

With best regards and wishes

    Hi,

    I am suspecting that the core is stopping the code execution because maybe the clock stopped but we need to debug this first.

    Will you be able to toggle some GPIO so we can see if the code is executing up to certain parts?

    regards,
