1) Yes I am aware of the recent update on the EtherCard library. The fix has been integrated to the current firmware 2.1.1 code:
https://github.com/OpenSprinkler/OpenSprinklerGen2/blob/master/enc28j60.cpp
which will be released soon.
This explained the few cases I’ve seen before that the controller locks up after some amount of time. The good thing is that the firmware uses a watchdog timer to restart the controller if wdt_reset is not called in the inner loop after a couple of minutes.
2) Thanks for the change to the icon. I will check it out and integrate it.
