Hello
I'm trying to use ADC (from RCM4300 module), I don't have problems to get analog voltage in LN0-LN7 pins, with a range from 0 to 2 volts, but unfortunately we have a lot of noise in the sampled values.
I have 2 questions:
1) Is there a way to minimize the noise in the ADC?
2) I do not use the VREF pin, so, is necessary connect it to ground?, whats is the VREF function?
