msp430 +adc

i am using an NTC thermistor and MSP430 to measure temperature between 0 to 50deg C.

ADC10 in msp is programmed to take 32 readings. each time adc10 finishes takings its reading. the first 1-2 readings are quite away from the rest of readings. eventually the readings are stable with a couple of counts different.

has anybody faced same issue.

Also can some please commment on what is the best technique to average these readings.

Hi

Use a delay after enabling the ADC and befor start sampling - for letting the system stabilized (the REF)

All the best
