Hello. I have nice operation of my VESC 4.12? from China when I operate in PWM mode and connected to a Futaba R617FS receiver.
I used the VESC Input Wizard to calibrate the VESC to the pulsewidth range of the R617FS.
Now I have built my own electronics to generate RC pulses, for use instead of the RC receiver.
My electronic assembly makes pulses just like those of the RC receiver: same pulse period, same range of pulsewidth.
The VESC responds to the signals from the RC receiver and it gives a very bright green LED.
If I wait until well after VESC power-on to turn on the Futaba T8FGS transmitter, the green LED stays dim at VESC powr-on.
The when I turn on the transmitter 30 seconds later, the green LED becomes very bright and the VESC responds to changes in pulsewidth.
All good so far.
However, for my home-built electronic things, the green LED remains dim when the VESC is receiving pulses from my hardware.
Never get a very bright green LED.
I have observed same pulse amplitude, same pulse period, same zero-signal pulsewidth as for the RC receiver.
Note: I am powering my VESC from an AC-DC converter. 20 volts. Through a 30 foot long 12-gauge wire-pair + 20 milliFarad cap at the VESC.
This works OK for use with the RC receiver.
What might be wrong ?
Under what conditions does the green LED change to glow "very bright" ?
Thank you for your help.
