I want to apply a fixed frequency onto the board instead of a frequency range that is provided in the software. I want to develop a software in LabView that does this. Does anyone know which pin I can apply a voltage with a fixed frequency to? Is there a way I can directly communicate with the board without using the software? Also, how can I get the impedance data directly from the chip? Another question I had was what is the purpose of the SCL and SDA pins?
