How to Debug Time Critical Code using an Oscilloscope
From time to time you have to debug time critical code. If you are using interrupts, you are interested in the actual performance on the code. This is especially true, if you are using timed interrupts. In this cases, using the serial interface is impossible. If you write to the serial interface, the whole timing…
