Hello,
I have my adc reading the temp sensor module in my MSP430FR device, but I'm a little lost as to how to interpret the results. Using the equation below
Is V_30 degrees C the below value V_sensor in the below table (top row)?
If so - is the proper way to calculate temp the following?
Read ADC value (my value is 0xF0) and convert that to a voltage. In my case using a 3.3V reference I get (3.3 / (2^10)) * 240. 0xF0 = 240 so I just use the decimal value and this yields about 773mV. I then plug this in to the equation in the first screenshot?
It seems like multiplying the voltage difference by such a small number as 0.00355 will not yield very accurate results. Is there anyone who could elaborate on this process from the point of having an adc code from the temp sensor?
Thanks.
