The datasheet specifies I should bias the COMM+ line around 1.5V. However, when I measure the voltage at TP1 with the oscilloscope probe connected to ground, the output from the oscilloscope is always 0V (i.e Ground)
I want to understand which way the current flows in the given circuit and what voltage I should see for every division.
The main current source is coming from 3V3. The other source is signal coming from the Coil attached to C23 and R18.
I am trying to get 1.5V at COMM+ through a resistor voltage divider.
