What is the max input voltage that the Openscope mz can tolerate on the logic analyzer pins. What about the GPIO pins? In the documentation I noted the Oscilloscope has +/-20V measurement range and +/-40V tolerated range (in some forum). But for the logic analyzer I see only a specific mention of 3.3V. I want to be sure before I connect the logic analyzer to either 5V (some Arduino's) devices or 12V devices (e.g. old DSC832 home security board).
Reviewing the PIC32 datasheet, and assuming I am correctly interpreting the Openscope reference manual, I can guess that the DIO[0-9] pins are 5V tolerant. Am I correct? Also, to ensure that the scope is protected I would need to not only have a voltage divider in place, but also a zener diode to ensure the voltages remain within range... what do you suggest/recommend?
