How to run a virtual plotter in software#
In virtual mode, a
Plotter behaves as though it had hardware attached,
but doesn’t actually attempt to set pulse-widths on the servo motors.
Plotter is unable to connect to
pigpiod to communicate with the hardware,
it will revert to virtual mode automatically.
It’s also possible to force a plotter to run in virtual mode, by instantiating it with the
virtual argument, for example:
bg = BrachioGraph(virtual=True)
Whether or not the plotter runs in virtual mode, it’s also possible to use Python’s turtle graphics to
run a graphical turtle on-screen to represent the physical behaviour, with the
bg = BrachioGraph(turtle=True)
