24V up to 55A drain, not known if instantaneous drain constant. 75mV==50A at shunt. Refresh rate for display is 500mS. PWM frequency unknown, sample duration unknown. Need to smooth samples for steady readout? Currently variant readout every cycle on const. load. Is it as simple as a large capacitor across the shunt to persist the current a bit more? BTW I do not know if 100% duty cycle ever reached-prob not as problem exists on full speed. Hopefully it won't upset my speed control too much. readout along flat varies from 1.2 to 9.8A in a cyclic manner of numbers, the extremes being rare-up to 10-15 sec per cycle of them. The highest readout is prob correct, just have to catch it more often. Capacitor across shunt will have to take at least reverse 2V to allow for electronic braking effect. No rev current occurs. Cannot use diode protection as fwd threshold too low. Advice please.
