How to connect a thermistor to my MSP430 and other ?'s

3 posts in this topic

Hey guys, I'm completely new to micro-controllers and I'm having trouble using the search bar. I think I'm so clueless that most people are assuming basic knowledge that I don't have yet.

 

I'm trying to connect a thermistor to my MSP430 and read temperature. I found this post on in the projects section :

 

 

viewtopic.php?f=10&t=2524&p=18608&hilit=thermistor#p18608

 

 

It looks like its exactly what I want to do but I'm having trouble understanding what's going on here. ( What pins to connect the thermistor too? how to upload the code files onto the chip?)

 

 

I've been watching c programming tutorials on youtube but I'm not quite sure how to apply that to the MSP430.

 

Does anyone know a link or resource I can read that can explain this to me like I'm 5?

hello.

 

i'm new too and there appears to be quite a steep learning curve ahead, a few new concepts to absorb and a lot of jargon to take on board. best to take it slow and steady, every journey begins with a single step, etc.

 

What pins to connect the thermistor too?

 

from your link:

 

The circuit is basically: Vcc

And on the msp430, the pins can have different functions. So the code sets this pin to act as an analog input. The analog input becomes a number from 0 to 1024 (depends on the resolution of the analog to digital concerter). You can read the same voltage with a normal multimeter. The code then uses an algorithm to translate that number on that pin to the actual temperature. The algorithm is borrowed from reprap code.

 

Energia can be a good tool to start playing with, but you can't run that code from the post directly. It will let you read analog values with less code than proper C.
