HELP! using vm110 to record analog signals to a text file

hi

i have just bought the vm110 USB experiment interface board. i want to use it to record two analog signals to a text file.

i was shocked to discover that there is no simple program that will let you do this on the CD. do they expect us to learn a programing language and write the program our selves? thats mad!

can any of you guys point me to a program that will record data to a text file. i just need to measure two (0-5V) signals and record a value every second.

Thanks in advance -matthew

You may try VBA (Visual Basic for Applications) programming.
See some example codes in thread:
[forum.vellemanprojects.eu/t/k8055-programming-with-visual-basic-for-applications/311/1)

Using VBA you may very easily get the values to Excel sheet.

This is to put the values in excel with VBA. How do I put the values from the analog inputs in a label in VB, without use of any other application? And how do I store the value with a timer? I’d like to see a the voltage change, every minute or so.

Sorry for borrowing this thread.

Hi Matthew,
Maybe you are in luck. I was working on some code for the extended USB interface board when I saw your message. I have knocked up an executable in Visual Basic for the K8055 (VM110) that I think will meet your needs. It displays the voltages of both analog inputs and records them in a text file at the same time. I can email you a zipped version of the program for you to install, if you want the code (VB2008), let me know.

I’d also like to have that file if its ok with you? I’ve been looking for a way to measure the voltage of the analog inputs for a while now.

I’ll email the zip file to anyone who wants it, just send me an email.

He can use Language C :
with :

FILE *f;

and :
f=fopen ("text.txt","a"); if (f!=NULL) { fprintf(f, "%s", analog_donne); fclose (f); }
