      Hi, I need help about enabling the PWM from Raspbian. I'm up to date and using Pixel such as Raspbian version. On Codesys I'm using Analog input and digital input, + 2x 1-wire device. Everything work effectively but we are currently needing the PWM output to control Led driver.

      Everything is wired correctly according to tutorials. Into unipi the value is a real is I think that's mean 0-10 value.

      So is many question come with this issue. Is there something to write into /boot/config.txt to enable the pwm over GPIO 18?

      Should we set all power jumper to external?

      With my best regard,
      Mathieu lefrançois
