Conveyor belt Sushi! Testing out a 4.6" diagonal bar TFT display 🍣 📏 🖥
We got the round displays working on our ESP32-S3 RGB display driver, so now we're moving on to the bar displays! These are longer than most rectangular displays and are kind of fun if you want to, say, animate a sushi conveyor belt. We're having a bit of flakiness from this one; the hsync and vsync or pclk settings given to us by the factory aren't quite right because you can see the display shift up and down. There's also a flickering effect: from us using single-buffer display mode where we draw the next frame on top of the current one while it is displayed. The way to get buttery-smooth animations here is to double-buffer at a cost of twice the RAM requirement.

More belt sushi! Testing a skinnier 960x240 bar display 🍣 🍣 🍱
Much like our 4.6" display we just tested, this 3.7" display is a looooong and thin boi. It has 960x240 pixels and a 40-pin RGB TTL interface. We're testing it out by drawing a cute sushi animation on it - and we see that while we still get the 'not double buffering' flicker, we don't see the image shift around like the 4.6" - which means maybe we've got more-stable values for the hsync/vsync.
