Signal input help

I'm using a VESC to control the BLDC spindle motor on my Duet Ethernet (FW=3.4) mill. Having recently configured a different spindle for the same mill using PWM I would like to set this one up to act like the other, i.e control through "spindle" in DWC and use M3 .... in my gcode program. Unfortunatly the VESC doesn't support PWM input. PPM, ADC (duty cycle), NRF (whatever that is) and UART are the options. Is there a path forward to making this happen? Thanks

@3DPMicro based of this thread here:

PPM or analog (with a PWM -> analog convertor board) should work. I would try PPM first.

@T3P3Tony thanks. I have a converter on the way
