Dear Forum Members!
I'm trying to sample the external ADC and covert the LSB value to Voltage. It is not quite clear from the datasheet how to do it and what the internal voltage reference used by the ADC.
This is the set up:
I'm sampling the battery voltage with the external ADC through a voltage divider that makes sure that the max voltage when the battery is full (4.35V) is 0.821V on the ADC input.
VS = 2.3V
This is formula I'm trying but it doesn't work:
f32Vin = (f32ADC /16384) * f32VRef;
Where,
f32ADC is the sample acquired in LSB
f32VRef is 2.3V
f32VRef is 2.3V
Could you please shred some light on what I'm doing wrong?
Thank you in advance!
Viktor
