Hello Team,

We are trying to Read the Voltage through the LTC2945 chipset.

Whenever we are reading the controller register 1e and 1f we get the random error like " Read failed or Resource is temporarily unavailable".

This is a critical parameter for our application kindly suggest us some solution for this issue.

Hello,

As far as resources being unavailable, there is a busy bit in the CONTROL register, but that only affects snapshot mode. I suspect that the issue may lie in your code, as natively, the part has no "resource temporarily unavailable". Can you get a scope shot of a failed transaction please?

Thank you and best regards,

Brad
