Now, admittedly, this is 600 MHz beast (the NXP i.MX RT1062). But I’d like to think it’s still impressive for the hardware involved. As mentioned in the Twitter thread, to eke out the performance I had to implement an 8-bit parallel bus using FlexIO along with DMA (all written in Rust) — but with that implemented, the display is pretty zippy.
