In some few situations, another microcontroller can be abused to sample an ADC or a digital pin as fast as possible (for the limited amount of time the internal RAM can store) and then have these samples sent to a PC for view.
Obviously - it requires the microcontroller to have a suitable sampling speed (and memory depth) in relation to the signal that needs to be sampled. And the signal normally needs some specific behaviour that can be used as trig signal since the memory is too small for just dumb sampling. A digital oscilloscope is one of the first instruments that should be available when working with electronics. In some situations, it's possible to use an analog scope, but they are often very problematic in relation to one-shot events in microcontroller circuits. |
