Trying to use VESC to drive the blower motor in a car. Yes I know it's not wise to use hobbyist quality parts for automotive applications...
The PWM speed signal from the 2009 Camry is open collector, so that means lower duty cycle maps to higher speed.
Is there any way to change the mapping to do this? I was thinking of making the throttle curve have a negative slope, but can't do it. In the PPM app, I also tried changing
"Pulselength start" = 2
"Pulselength end" = 0
but that didn't work either.
appreciate your help
