Hi Chris,
Yes, I am using the same sensor and Thanks for all your help.
I had some problem in connection, which is solved now. You pointed out correctly earlier because problem was in INA/INB pins only.
For now I am getting some values for Proximity data and frequency count. But Frequency count doesn't change if I change the value of Response time though LDC configuration register (add: 0x04). But it does changes correctly when I change the Fext.
For e.g Fcount gets double when I doubles the Fext. But if I change the response time from 384 to 6144, it doesn't change.
Do you have any idea where could be the problem?
Thanks in advance!
