What is a propscope?

"The PropScope is a two-channel oscilloscope that is capable of reading 25 million samples per second with ten bits of resolution over one, two, ten, or twenty volt peak-to-peak waveforms. Power is provided through the USB port requiring only a single cable to connect the PropScope to any laptop or desktop PC."

Why would I want to read samples and what could I use it for?· Back to the original question:

Chuckz,

The Propscope is an USB oscilloscope that uses the Propeller Chip. To understand what an oscilloscope is, see http://en.wikipedia.org/wiki/Oscilloscope

USB oscilloscopes work with a PC and use the PC's monitor to display the signal as opposed to stand alone units which which have all the hardware in the case including the display.

You might take a look at Parallax's Understanging Signals book in pdf - http://www.parallax.com/Portals/0/Do...ic/Signals.pdf
or this - http://www2.tek.com/cmsreplive/tirep...00_2280_EN.pdf

You can also have a look at the Propscope documentation. Hope this helps.

I think you mean to ask,"Why do I need a Propscope?"

Most hobbyist do not really need a Propscope. But it is nice to be able to check the output timing of a pin. If you are looking for a specific pulse timing it is very handy. Also if you are outputting analog signals it is really nice. You can look at the wave form to insure the signal is correct.

If you ever get one and use it, you will probably ask how you got along without it.
