Pdm Resistive input

Post by serhatovan » Tue Dec 20, 2016 1:25 am

Hello,

We try to make a fuel gauge and we are using resistive input of pdm. We can't read resistor value from that input, we can only read voltage. Our fuel sensor is 0-65 ohm. When we use 50 ohm or less resistor we can't see any volt value on the screen because of 2.2k pull up resistor of pdm input. It doesn't have sensitivity to read the voltages below 0.1 volt. That's why we cannot read values between 0-50 ohm.Could you please help us about this?
