i have a very simple question,
i just bought the above mentioned logic analyzer, and i had hoped it would have been so simple to view if a digital pin receives a HIGH or a LOW signal.
i just came to the conclusion that i will take more than that to view this.
i was at first aming to read a photocell NPN NO, this type gives a LOW when the beam is broken, and stay's HIGH when there is no obstruction between the beam and the reflector.
nothing worked for me,
this LA comes with some fancy free software, with loads of protocols that can be read, but i did not find what i needed.
is it in any way possible to monitor photocells (or a digital input pin - HIGH or LOW) with logic analyzer?
i connected te GND of the photocell (and later on the GND of the arduino UNO R3) to the GND connection of the LA1002.
then i connected the signalwire of the photocell to channel0 of the LA (no pulses to be vieuwed )
i then did the same with the arduino pin (Pin 7) to channel0 and GND to GND
what could i possibly have done wrong?
Thanks in advance,
