Screen Rotation Problem HX8357-B


New member
I rotated the screen 90 degrees with the 36h (MADCTL) = 2h command but it won't write to any column greater than 320. I haven't seen this problem in other controllers. Anyone have an idea what to do? It's a 320 x 480 display. So the rotation changed the direction of the display correctly but won't write to the end of the screen.

Is the display defined elsewhere in your code as 320 x 480? Might need to be changed to 480 x 320.
