BT81X rendering ASTC image from flash
« on: February 18, 2021, 03:26:02 PM »
Hello,

I have MatrixOrbital EVE3-35A-IPS screen and trying to render map tiles (240x240px ASTC 4x4) directly from attached 128Mbit flash.
I can render 1 image without transformations but if I try to scale image then screen start blinking black sometimes. EVE works on 72Mhz, PCLK=10
If I copy image from flash to RAMG then it works fine but direct rendering does not work. I don't understand what the reason for direct flash image rendering if it can't process even one small image.
...Or maybe I do something wrong.

Best Regards,
Dmitry

I may suggest to use larger ASTC block (ASTC8x8) if possible.
