Hi all, this is a reply to my own post and a call for advice.
When soldering up my level shifters, I fortunately did build a couple of them, not only the two needed for the IOIOBox. With a substitute level shifter my freeze-up problem becomes much more rare. Beforehand I had a freeze-up within minutes to 2 hours after starting the communication. Now, with another level shifter, the interval is 8 - 10 hours. These are cheap level shifter, bought on-line for less than 6 Euro. To me this looks like violation of tolerance limits of signals exchanged between level shifters and IOIO board. Unfortunately, I have no equipment to check that. And being more a software than a hardware guy, I am not sure I would find something. However, could that be the reason ? Or is the reason for the freeze-up tied to intolerances of signal treatment in the IOIO board ? Would it be worth while to dig into firmware versioning of the IOIO board (which I would like to avoid) ? Any idea around ? Would be great to hear something.
