Situation : Mean Well PWM-120-24 led driver (supports 0-10v dimming) connected to M-Duino 42+ analog output A0.5 and GND. Switch set to A0.5.
Problem : analogWrite(A0_5, 0) gives 0.6v instead of 0v. Decoupling the driver results in the correct 0v on the A0.5 pin.
Question : Why 0.6V when the driver is connected?
