Topic: read a nalog step signal with diffrent steps (Read 547 times) previous topic - next topic


i want to compare between this two diffrenet signals using ADC ,but the two signals is continuios ,i don't know exactly when i will start to read the signal ( the time slot, that i read , depend on the time ,when i started to read  ) .is there a standard method used in this situation ?

Thanks in advance


Yes, there are standard ways of triggering the measurement. Your oscilloscope might have a standard output connector with the "trigger" signal on it. That can be connected to an Arduino "interrupt" standardized pin.

Another standard way is to build your own trigger from a comparator.  The LM339 comparator can be wired to the circuit to produce an interrupt for the Due.

If you can control the signals, you can make an event that will be a "marker" to indicate the beginning of a test.
I am going to get going.
