I'm looking to make an LCD themometer using a standard Unicurve thermistor 100K6 from betatherm with a 51K parallel resistor for linearsation. There is a standard steignhart calculation for the resistance of the thermistor. I need to generate a look up table to convert fron the 14bit ADC value to converd to a Centigrade display read out MSP430P325AISP.. Thanks for any help.

Hi everyone! Can someone help me on how can I use an MSP430G2231 to read an external thermistor, scavenged from an old computer motherboard? I tried to use the temperature reading example program without success. Thank you all in advance.

For the experts out there this should be an easy project. I am looking for a prototype miniature temperature display system using a thermistor with an LCD display. I picked the MSP430 chip because of its in-built LCD controller, but other micros can be considered too. Anyone interested in the U.S. please email me with a price or for futher details. Thanks, Joseph

Hi folks, I'm working on my next project to shorten the warm-up time of my hybrid-electric Prius. My approach is to use an MSP430-F2013 as the feedback controller. It monitors the thermistor voltage and then uses PWM to adjust the voltage: http://hiwaay.net/~bzwilson/prius/pri_temp_circuit.jpg Perhaps a little 'over kill,' I'm also using this current project as a training exercise for...


tapping existing signal wires

Hi folks, This is little off-topic but related to my MSP430-F2013 project to adjust the Prius engine coolant temperature. I need a simpler way to tap three wires feeding the hybrid vehicle ECU, ~28 gauge, multi-strand. Today, I cut, strip, solder and heat-shrink my three wire taps: (1) ground, (2) 12DC and (3) thermistor lead. I do this because the automotive connectors are unique to the P...


MSP430F2252 ADC problem

Hello, I ported known working code from a 1232 part to a 2252, and want to add an ADC input on A15. I presently use A0, and it's working correctly. I am running the IAR IDE. Here's my setup code for the A0 and A15 ports. A0 reads battery voltage; A15 will read a thermistor: void TurnOnADC(void) { ADC10CTL0 = ADC10SHT_3 + ADC10ON + ADC10SR + ADC10IE; ADC10AE0 = 0x01; // P2.0 A
