Bitmap is only allowed for use with 1 interrupt

As I understand it, hardware interrupts should only work with simple variables and handler functions should be in the main loop, right?

No HW int can do anythink what is reqiured ,but in lvgl context , cant call lv func! (exception in docu)

And your example is waste of hw timer because for time managed updates exist more effective code.
