You will need to tap RUN to restart the scope. -* The OFF trigger mode prevents all triggering and Scoppy will set the horizonal position so that it is displaying the most recent samples (it normally tries to find a trigger point near the centre of the sample record). This in combination with a long Time/Div setting is equivalent to roll mode on many 'scopes. ## Troubleshooting * If your phone has a Micro-USB connecter then check that the Micro-USB plug of the OTG cable/adapter is plugged into the phone and not into the Pico!
