Hi! I’m working on a clock project, and I started from posts I found in this forum on how to do it. My clock has a background image and chrome-keyed images for hands. Hands are moved using lv_img_set_angle() function. I’m using a double buffer of 10 display lines each.
When the hand is redrawn, the background image is modified, like it’s part of the copy-rotate-redraw process, together with the hand image. Any idea about how it comes from and how to avoid it?
Thank you for your suggestions.
