Hi all,
I am working on a project where I am driving LEDs based on the RPM of an engine.
It isn't the typical method where you just listen to the ignition events of a coil, rather, it is coming from a standalone ECU that outputs 0-12V square wave (frequency depends on RPM).
I know I can use the LM2917 to do this conversion, however, I am not able to simulate it in Multisim. I tried looking up the circuit diagram for that chip, but I don't know how I would immitate a "charge pump".
In any case, I hope someone has some insight into my options or has a solution.
Thanks,
Phil.
