DSO nano is widely used in Megasquirt scene. It would be perfect if it could simulate Crankshaft wheel decoder signal. These signals are TTL level pulse train. It is continous pulse train with a missing (one or more, some times no missing pulse) pulse as Top Dead Center marker.
If DSO nano could simulate wheel decoder with configurable frequency (RPM), configurable number of teeth (pulses) and configurable number of missing pulses, It would be perfect for DIY ECU hobbyist.
