Axs15231 transform issues #17

Open Hannah-GBS opened 2 days ago

Hannah-GBS commented 2 days ago

I'm having the issue where using rotation: 270 causes the display updates to be very slow if a lot of pixels are changing, and I read that rotation is software based, whereas transform is hardware based, but it does not appear to work correctly with the axs15231 component at the moment. Setting any of the transform properties (swap_xy, mirror_x, and mirror_y) to True (and commenting out rotation), causes the T-Display Long to show a very glitchy version of my LVGL page on part of the screen, then it repeats this ~3 times. I've tried switching the height and width properties and all combinations of the 3 transform properties to no success.

I'm not sure if this issue is present in the dev version of the qspi_dbi core component this is based on, or what ETA there is for that updated component to be released. I'll probably try the dev build tomorrow but I don't know to what extent it supports this display either.

Yep, you are right. I didn't find any working version of hardware-based transformations yet, including official examples. I'll try to find a solution and most likely contact support next week
