Is there a virtual propeller application?

Work is slow sometimes, and I can't bring my prop bread board in and have that hanging off of my desk.

Is there a virtual propeller application that I can load a program to, simulate some basic highs and lows to pins as if it was connected to the chip on a com port and then watch how the code interacts with that and outputs on pst?

Does viewport have this ability?

    Hi,

    don't get catched doing private things at work

    I'll try not to idea.gif


    As usual Stefan, you are the man! I can't wait to try it out tomorrow.

    Translation to English
    Testbench.spin with propeller signal generator of John Ahlebrand generated at pin 10 and 11 analog signals :
Sawtooth, triangle , sine, square , etc.
If you add in the program testbench , the two lines sco : "Spin Scope" and a sco.start so appear only digital
but no analog signals.

The program can be found at Speech / Sound Propeller signal generator Author: John Ahlebrand

What can you do to make the analog signals visible?
Yours sincerely
