You don't initialize sFilterConfig to zero, so sFilterConfig.FilterMaskIdLow could be a random number upon POR.

What do you consider as fails to detect?Do you mean that the slave device does not ACK the master when the master sends the slave address on the I2C bus? Have you looked with an oscilloscope to be sure that the signals look good with minimal slew?You...

So you should read and save the offset voltage before there is any power applied to the voltage divider. After when power is applied, you read the voltage divider and you subtract the offset voltage from it. That should be your calculated voltage you...
