So I was following a lvgl guide to create an autonomous screen with buttons but I got a little confused once it got to using functions. I created the function they said to follow and made a slight modification to it. However, the tutorial did not mention how to call the function to create the buttons and I was wondering if anyone knew how to. Below is my code:
lv_obj_t* theButton = createBtn(30, 30, 30, 30, 1, 'h');
lv_obj_t* is the type of an lvgl object pointer, you didn’t assign the output of the function to one, so of course the statement in your comments would not compile.
The title string should use double quotes not single.
“h”
single quotes with on character in it is a char variable.
