LC Doesn't Repond to Reset Button

I'm doing some work with an LC using both i2c channels. Sometimes the LC will hang and pressing the reset button won't bring it back so I have to pull and replace the power lead.

This is not a huge problem but I'm curious as to why this might be happening.

Also, this morning I noticed that when I attach a logic probe to the LC and run my program that uses i2c to pass data between the Teensy and a Pi after a few seconds the Teensy hangs and won't come back. The probes are properly grounded and the behavior stops when I remove them. Any ideas why?

Thanks,

Eric
 
Unless I have missed something about the LC; that is not a reset button, it is a reprogram button and when you press it the LC will go into a non-responsive looking mode until either the teensy loader program sends it a nice batch of code or until the power to the unit is cycled.

I wouldn't like to try to comment as to why your code hangs the LC without seeing both your code and a decent picture of your wiring, sorry.
