Where cani find equipment that makes my laptop work as a signal generator
which makes it possible to simulate a crankshaft pickup signal . The
pickup detects
tooths on flywheel for the starter motor.

I've written custom code to do this for ignition timing control with a
laptop. In my case, I used the parallel port to read the (conditioned)
signal from the crank sensor, forwarding it after an RPM-dependent delay
to the ignition module. It is not an especially-complex thing to do,
but I've never seen anything "off the shelf" with comparable
functionality that wasn't tied to specific engine-management hardware.

Thank you very much for the answer. .
Im working with volvo penta diesel engines. The pickup signal is about 3-10
v AC depending on rpm. I suppose its a square wave but Im new int o
oscilloscopes however I have bought Pico ADC 212 to try to learn more about
it. Sometimes I need to fake a signal to make the cpu think that the engine
is running to check if the the engine stops if for example loss of oil
pressure occurs. (this in generator sets running 24 hours a day)
How do you use the paralell port to read the signal? And how to create such
signal ? Im a mecanic so I need explanation step by step if you have
time........
Thank you
Ingvar
