Question

Stuck on displaying Vector graphics with Hardware Accelerator

Hello, I've been working on stm32u5g9j dk1 board, with a 466 * 466 oled display that I've changed.
It works great with bitmap widgets, or vector widgets on a software rendering.
But if I change it to hardware rendering to use neochromVG, the display only shows bitmap widgets, not vector widgets.
Software vector rendering has a performance issue, so I'd like to use hardware vector rendering to look nice and smooth.
I attatched main.c and ioc file. Could you please have a look into it and help me out?
If you need anything more, reply me and I'll send you rest of it as soon as I can.

Thank you.

Hello @miresu ,

Have you checked at our STM32U5G9J-DK1 TBS? I think you can reuse most of it for your own project.
