Hi All,
I would like to confirm with all of you for
converting ADC readings into battery voltage.
From MPR datasheet, we have a formula to
change from ADC readings to voltage at ADC channel 7 for measuring battery
voltage.
Vout = Vref xADC_FS/
ADC_output
Vref = 1.223 V
ADC_FS = 1024
ADC_output = reading from ADC channel
7.
Is this formula can be applicable to other
ADC channel readings (ADC0..ADC6)? Currently, I got some readings from new
sensor type, and I would like to change ADC output to voltage for calibration of
sensors.
Thanks you very much.
Regards,
Aung Aung Phyo Wai
