Hy /diy/ , i need some help :
I have an MSP430 microcontroller and with a thermistor i have made a themperature sensor . The hardware part is done but now i have problem at the code part , i didn't quite get useful information on the internet and i wonder if you could redirect me on useful sites or give some tips. Thanks :)
>>
It's been a while since I've used the msp430 but I'll try to help.
Are you using that nokia 5110 display?
If so, have some info/code that might help you.

Good community site:

Assuming you will be controlling some HVAC equipment with that thing, how are you handling the higher voltage? I was thinking of making myself a thermostat but my unit is all 120VAC controls which makes it a bitch
>>
The display has 14 pins , it is not like in the picture . The project is not made for hvac equipment , but anyway I used a voltage divider between the thermistor and GND . It will just be plugged by usb in laptop .

Could you be more specific with what's your problem?

You need to use ADC to measure the voltage and use a table+interpolation to calculate the temperature based on the voltage.

And when in doubt, refer to datasheet.
>>
My only problem is that i can't find tutorials / tips for the code part . This is quite an unpopular MSP and i want to know where to find some projects to make an ideea about coding.
>>
>>914437
What part of it, exactly? Or do you mean the whole shit from processor initialization to displaying shit on LCD?
>>
whole shit , although i think it doesn't have more than 20 code lines
>>
>>914437
I assume what you're trying to say is that you can't find an SDK for that particular part, not that you're having trouble writing what amounts to a for-loop?
>>
yes , sorry for the lack of details

Was afraid of that.

Hope pic helps.

Do you have any coding experience?

this is the specific MCU
I have medium experience in C and C++

I'm not seeing the specific problem here.

From what you're saying, you already have everything you need to execute this project.
