temperature data logger with rs232

[parii]

hello friends...

i seriously need your help in my minor project.i have temperature sensor made using lm35 and microcontoller .I am using MAX232 Module to commect my hardware to labview.now i want to make a temperature data logger using labview. i see lot of example but iwas not clear how to make all of them were different.actually i have made many program using labview but still am a learner and tis is my first when i am connecting hardware to it.so please please help me i have only 2 days to submit my work.please could any one make a vi for me.please!!

1. You couldn't afford me

2. You have not even hinted at what the data format is of the data coming from the microcontroller to the computer over the RS-232 port.  This is what is most important.

Otherwise, I recommend you look at the Simple Serial Read example in the LabVIEW Example Finder (Help->Find Examples).

sorry..i just want help ..i am am sending you picture of that..it shows reading in degree celcius.

Sometimes, a picture is worth a thousand words but, in this case, the picture is pretty worthless. How can anyone get some useful information from that? What is the micro and how have you programmed the serial interface? What is the format of the data being sent? Have you done anything at all to read it with LabVIEW or another terminal emulator program?

previously i took data on lcd to see if it working or not..it work and show data.  i think the out put is hexadecimal number

ohh god cant somebody make a sample vi for helping me just a temperature data logger that can read data using rs232

We can once you give us some useful information.  Do you have the microcontroller code?  Perhaps we can figure out the serial protocol from that.

So instead of providing any sort of useful information in order to actually help you, you decide to cry. There are all the examples you need that come with LabVIEW. Good luck.

the data format is binary.And all i want to do is to take data from rs232 and make a log file of temperaure.
