Hey Caleb, I started coding with arm assembly, and I learned that pretty well. But due to having to switch to C++ for a different project I struggled a lot with the syntax which your videoes helped a lot. Understanding how it works at a low level but not knowing how to do it is really frustrating.

Pointers - while conceptually are not too complicated to understand - in practice blows the hell out of the brains!

08:03 Hi Caleb, could You explain, why we don't need to use a dereference operator (*data[i]) to get the strings in std::cout in this examle? if data[] is an array of pointers, and we get specific value from that array, shouldn't we get the address of the string as a return, rather than the string itself, since we are not using a dereference operator here? Or is do the brackets in the array reference dereference the pointer by definition? Great tutorials btw.!

Actually, reference pointer could be used instead... in the second example.

Well I have no idea why it didn't work just copying the lvgl object pointers into an array - but it did when I made an array of pointers to pointers of lvgl objects?! static lv_obj_t **ta_time[4] = {&ui_SettingsTime1, &ui_SettingsTime2, &ui_SettingsTime3, &ui_SettingsTime4};
