I got the beast of a widget - the Lilygo T5 4.7" working with GFX.

Man this thing is hard to code for. I actually have to use both cores of the CPU to update the display due to having to transfer from the frame buffer to DMA capable RAM as I'm feeding the display over I2S.

This is mainly because the e-paper panel does not have a display controller. To save money, the MCU is the display controller. The panel is wired directly to the MCU via like 14 pins and driven with I2S. It is very finicky, and timing sensitive. I thought the RA8875 was bad, but it's positively well behaved compared to this.

I spent most of my morning fighting bootloops, some without any error messages.

Forgive the sound. Alpha blending demo w/ 16-color grayscale
