In GDtool 2.5.1 there is a bug that prevents adjusting "PWM/Analog offset" spinbox whenever analog has been selected from drop down box. To workaround this, temporarily choose PWM from drop box and adjust the offset value. After value changed, switch back to "Analog in" mode. Press ''Set'' after offset value is changed and mode is set back to Analog in (no need to press during adjustment). | In GDtool 2.5.1 there is a bug that prevents adjusting "PWM/Analog offset" spinbox whenever analog has been selected from drop down box.
