Automatic changing anlalog output voltage

[Dejv]

Hello, I need advise. Here is my problem:

I have measuring card NI USB-6009 and I would like to change automatic output voltage from Analog output. 

I need automatic continuously change voltage for analog voltage output from 0 - 5V.

Any suggestion? Thanks

This example may be of help:

Does this mean you would like to output a waveform?  Or, is the voltage adjusted in response to some type of feedback?

Sorry I writing from another nick, but still I am Dejv 🙂

I would like with this voltage control transistor for simulate resistor. On this resistor I will display to XY graph current dependence on voltage, that is electric power.

So I would like to control this outupt voltage evenly from 0-5 volts.

It sounds like you are looking to perform a voltage ramp.  Here is a simple example.  Hope this helps.

If I would like in voltage ramp do stop button how can I do that? I'd like to be able to do it anytime when voltage will be accrue I can click on button for stop and reset accrue. 

Thank you for advice

Hi,
so you wants to restart or stop ramp generation? Both features could be easily implemented into that code...
See the attachment.

Thank you very much.

And how will be looks if I would like stop and reset in one button?

Edit: I woul like to in one button: Start,stop/reset. So...For one click do start and for second click do stop with reset.

Thanks 🙂

Dear adssad,

have you tried to solved this task by yourself? I think writing previous two posts may took longer time than implementation of the feature you're asking for...
