Hello I have a question about the parallax scope.· I currently have a small brushed motor connected to an hbridge.· I have the input·pwm·duty cycle at·50% and I can view the voltage across the motor on CH1, with·CH2 disconnect from the scope.
Conversely,with CH1 disconnected I can view the input signal to the bridge on CH2, but when I try to view both signals at the same time, the motor·goes to·100% instead of 50%.
Whats up with that??
btw:·The battery connected to the motor is 9.6V
