#101733 - oscilloscope Responding to: ???'s previous message |
You can also try to insert HUGE delays (in the order of several (tens of) seconds) and watch what happens on the bus using the LEDs, but better using two voltmeters and measuring DIRECTLY at the MAX's pins (breadboards are sometimes tricky) - but I would really recommend you the oscilloscope.
This is what I did originally when I started trying to figure this out, and I could see the changes on both pins. I've also got a logic probe and I can see that its actually "pulsing" the pin. |
