HELP: how can i plot my data from microcontroller to pc?

[ivanonair]

Sirs and mams!

I have a microcontroller and i connect it via serial port to my pc. I want to plot my data real-time using a GUI. But i dont know how? Can you help me. Thanks a lot!

You write a suitable program on your PC - that's all.

I'm presuming you've already written the micro-controller program?.

Serial communication with PC using a microcontroller is not a big deal. If you can specify the microcontroller it would be easy for the "Sirs and Mams" here to help you

Hi,
There are a number of Windows freeware programs, look here for starters.

I am using a zilog xp microcontroller.

hi,
If the connection is RS232 and the data format of a common standard the Win program will not care which MCU you are using.

Whats the data type and format etc...

Thanks for the links! Is there any GUI made out from VB or Matlab can i download? Coz i dont have any idea on GUI programming. All i need is a program which can plot my data from zilog mcu real time (sine waveform or any kind of waveform or line) thanks!

Are you asking for VB source code?

 

[ivanonair]

Not exactly a VB source code. But maybe a source code too, but i think that is too much coz its the programmer's intellectual property. Maybe sample programs or codes on VB or Matlab which I can make a real-time plotting GUI from serial port that i can study with, and make my own GUI.

I dont mean the VB programme itself.

I mean source code for a VB, RS232 plotting program.
Do you have the the Visual Basic 5 PROGRAM in your PC?

 

[ivanonair]

Oh sorry sir I do have a VB on my pc. Can you help me how to make GUI using VB? I really need it for our project. Thanks a lot sir!

Look here:
This site is excellent for source code, I suggest you register.

Ok. Thanks a lot sir! Cheers!

If you just need to plot some data, output it from the microcontroller as comma-separated numbers, then paste it to Excel and make a chart. As easy as it gets - no coding necessary.
