When I use tether firmware v0.8.0, digital outputs 0 and 1 don't seem to work properly. They are at about 0.5 volts all the time. Legs 2 and 3 work as expected. When I use firmware v0.7.3, this doesn't happen and all legs work as expected.
Digital and analogue inputs work as expected in both v0.7.3 and v0.8.0 firmware version. PWM not tested.
Has adding the servo support somehow affected digital outputs?
