Arduino H7 Video - Display remains black when executed on the M4 processor #1048
Description
I have found a bug in the class Arduino_H7_Video. When creating an object with the call
"Arduino_H7_Video Display(800, 480, GigaDisplayShield); " // This doesn't work on M4
this works with the M7 processor, but not with the M4 processor. The display remains black. The call only works on the M4 processor if I swap the values 800 and 480 .
"Arduino_H7_Video Display(480, 800, GigaDisplayShield); " // This works on M4
But then everything on the display appears rotated by 90 degrees and a rotation with the function lv_display_set_rotation(...) does not work.
I use Arduino Giga R1 with lvgl 9.2.2 and Mbed OS 4.2.4
