PR11 Fan Speed

Postby Juf » Mon Mar 22, 2010 1:18 am

Hey,
So I bought the PR11 and everything is working fine. I was wondering if the Fans included in the kit are able to be speed controlled? If so could you give me some example code?

Good to hear that it is working fine.

As for the speed control, do check the schematic, if the fan control is connected to CCP pin (RC1 and RC2), you can have PWM output to control it. If it is connected to other pin, speed control will be difficult to achieve.

Correction to Ober's reply. The speed of the fan in PR11 CANNOT be controlled. This type of fan is using brushless motor with onboard controller, there is no way to change the speed for this type of fan.
