display frozen/unresponsive #177

Open olivluca opened 2 months ago

olivluca commented 2 months ago

This is more a question than a bug report, anyway, it happened to me twice that the display froze and was completely unresponsive. It's difficult to debug because I don't have a serial port attached and it happens very seldom (twice in a month). The first time it happened, I added a watchdog to restart the esp32. I'm quite sure that the esp32 restarted at least once due to the watchdog, however yesterday the screen froze but the watchdog didn't trigger, so I think that either the main loop was still running (so the frozen display is a bug somewhere in the library) or there is an hardware problem. The board is an esp32-2432S028R. I'm not 100% sure, but the problem happens after this line (i.e. after an inactivity timeout the brightness is set to 0 and I show a dummy screen to avoid registering clicks on the now invisible objects, when there is new activity that line switches to the main screen). Both time I saw the problem the screen was off, I tapped on it, it showed the main screen then froze.

I suggest to enable LVGL logging and save the logging... Maybe this will help to pinpoint the issue...

Thank you, I have no idea how to do that and it if it's even possible without serial :wink: Maybe I should upgrade the library first (when I reported this your repo was using lvgl 8.3.9). BTW, it didn't happen since last time.
