How to use low level active laser drive?

I tried this change, but the D11 output was high at the laser work
#define SUPPORT_LASER 1
#define LASER_PIN 11
#define LASER_ON_HIGH 0

Comments

  • invert the Signal by changing to :

    #define LASER_ON_HIGH 1


    be shure the Pin is not used for anything else, that won´t work.
