I'm lining up the next project that will follow the LED modification installs. The decoupling capacitor will be installed into all boards and then tested. The question is, what is the best code to test the propeller functionality with and without a decoupling capacitor??? My guess is the acid test is hooking up a scope to see the signal conformity. Since I travel, a large scope is not possible. It looks like the small Prop Scope could fill this requirement. Anyone have experience with this and recommendations?
