Hello everyone 
, I was testing the 6.6 Analog input and noticed that the readings are halved for some reason.
I used a power supply for input signal and an oscilloscope for measuring. I am using CUAV X7+ and the ArduPlane V4.3.3 firmware. my configs are the following, BATT4_MONITER as analog voltage only and I setup BATT4_VOLT_PIN 18 for the 6.6 ADC input.
Any help will be appreciated.
