Is anyone able to give me some tips on why I may be getting a core panic?
I’ve been playing with LVGL for a few days with an ESP32 and I have something on the display - I can create a couple of buttons and set labels for them. I’ve not yet got the button touch call back to work though.
I started with lvgl version 7.11 but I kept finding that the examples on the web were mostly v8 so they would not work because there are significant changes. I have therefore now moved across to use v8.1.1.
Originally in Ver 7.11, I could display a couple of buttons and get some touch response so I am pretty sure everything is wired up correctly. Since I moved to V8.1, it seems like when I try to configure and then readfrom the XT2046 touch sensor that I get the problem.
If I leave this code out (commented) then the display show buttons and I have the FPS showing in the bottom right, just fine.
// Register an input device when enabled on the menuconfig
lv_indev_drv_t indev_drv;
lv_indev_drv_init(&indev_drv);
indev_drv.read_cb = (void *) touch_event;
indev_drv.type = LV_INDEV_TYPE_POINTER;
lv_indev_drv_register(&indev_drv);
As soon as I include the last line there
lv_indev_drv_register(&indev_drv);
things go wrong:
See the last few lines of this dump for the error
