Hi there,
i have a Question, i search for a Result since a Year... how do i define it to use two Outputs sync.

Unfortunately, these three Attempts did not work in the Pin Config.

#define FAN_PIN PC8 & PE5

#define FAN_PIN PC8 and PE5

#define FAN_PIN PC8 + PE5

The Result is 0 Volts at Output PC8 and PE5

(I have the SKR Pro V1.1 board)

Greetings, Marta

You cannot do this in this way.

a pin definition is a singular IO pin only always.

Just wire the fans in series.

Hy Dust,

you mean parallel, in series is the voltage every time the half on the two fans and thats not that what i want.

My intention is it to resolve this in programming way.
