hello all, 

MCE wizard does not support hall sensors with the duty cycle method, so can I give duty cycle to  vsp pin (instead of throttle)?  for the hall sensor.

 kindly give any suggestions for  work hall sensor with the duty cycle method. thanks  in advance

Hi ,
Yes, the Duty-cycle input can be used at Vsp pin.
For doing this, Vsp pin is to be used as an ADC pin. The input at the Vsp pin is read by MCE in each 1ms. Using a custom script, the duty cycle needs to be calculated. A linear relationship between the calculated duty cycle and corresponding target speed is to be implemented in the script.
Note: The timer available in the script engine has a 1ms resolution. Therefore, this method can be possible only for very low-frequency input.

Thank you

Sushruti
