hi everyone, I'm from France and working actually on a project that enquired Miac and Flowcode...
The problem is I don't know how to program MIAC to show the temperature in function of the thermistance that I've chosen...
the thermistance name and caracteristics: CTN 10K
Spécifications
résistance nom.: 10 kohm
B-constant (±7%): 4100°K
courant max. admissible: 30mA
constante de dissipation thermique: 6mW/°C
constante de dissipation thermique: 15sec.
dimensions: Ø=5mm
so I think I need to use function Cacul in flowcode to make it happen?? any idea?? I'm confused and dispair!!

these are some values that I made
so I guess Miac will read the tension...but the tension read must be Convert to analogy and display in temperature number please!! help!![list=][/list]
temperature reading help!!

Hello,
Have you seen the sensor1 example from the MIAC examples download?

Re: temperature reading help!!
I did but it doesn't help!! I need it to read the tension deliver by the thermistance then convert it in binary to finally display it in real temperature!!

Hello,
I normally use a excel spreadsheet to generate a look up table and then use that data inside the microcontroller Flowcode program.

Hello,
You could use the example program located here to show you how look up tables work in Flowcode.
http://www.matrixmultimedia.com/mmforum ... =26&t=3543
Let us know how you get on.

Re: temperature reading help!!
things are getting better since we have talked...uhm I didn't use your program actually...I did another way...right now I'm having a new problem ... but I don't know how to explain ... if you let me to send you an image to explain?? how can I send it to you??
