Hi,
When doing offset calibration for pH sensor in Arduino we bring pH 7 to 2.5V as Arduino analog output is 5V. Does that mean when the same is done with msp430g2553 the voltage be adjusted to 1.5V as msp430g2553 analog pins output around 3V only?
When I tried adjusting the pot I could only bring it to a minimum of 2.5V with msp430.
Does anyone know why?
Thanks.
