Hi,
I was wondering if anybody can point me towards a way to get a working virtual oscilloscope so I can study waveforms for future projects. If anyone could help that would be great.
Thank you.
Most important: do you want to view analog values (scope) or digital signals (logic analyzer)?
You typically take a number of samples at fixed time intervals, then display that on a screen.
Analog input with analogIn() is very slow and only one channel at a time.
Digital input can read up to 8 bits (lines) at once from a port.
You can make a simple one using your sound card, they are not great but it will get you started on a budget. Analog scopes are not that slow, I can display 1 Gig signals on 4 channels concurrently on my teck scope and in color. I also have a coperable digital which is nice but a pain, maybe because I came from the analog world.
When my son was in college, the engineering students were required to purchase this, which came in handy for electronics labs.
Now he's a software engineer, and the tool is on my hands.
I just use a regular standalone 4-channel oscilloscope tho, no need to lug my laptop up the workshop for any testing I do,
If you mean Virtual as in simulated, there are SPICE circuit simulators, and I think you can even get something from Digikey
Says "through analog/power simulation", not sure which tool is doing that.
If you search "circuit simulator online" you can find this one
which is what I think is embedded in electronics.stackexchange.com for creating schematics.
I've only used it to draw up schematics there, I don't know how good the simulation part is.
search for sound card oscilloscope.
also, there are arduino projects on youtube to make an oscilloscope.
