Hallo
I am trying to measure a output from a LM3914 bar display driver with a pic12 the problem is that if you measure from 0V nothing happens, if you measure from 5V you get a variance running up to 1.2V.
The probllem is that the pic analog input measures from 0V and not vdd and does not detect the change.
The question: can you configure the pic to use vdd as the refferance or is there maybe a other sollution someone can sugjest

Thank you
