the mods I am making on my car ( 1981 Mercedes Gwagen ) include a electric fan instead of the mechanical one.
The new fan - speed - is PWM controlled.
Any idea whether I can do that using MSextra without a big effort, or is it better to program a PIC
For idle I am using the PWM option ...
Thanks
Oskar

PWM fan control
I believe all the timers are used so you have to make something autonome. I used a atmega8 to pwm the fan (not finished yet).

Re: PWM fan control
I took a look on the uC specs. It has 7 PWM channels and it does not look like all are used. Need to dig a little more tomorrow ...
