That depends on what you exactly mean by "controller". The hardware controller typicaly has capability of exposing selected pixels to essentially arbitrary voltage level for specified amount of time and the framebuffer abstraction happens on the driver level.
- userbinator 9y agoThe majority of dev kits and modules available abstract away that level and provide something not unlike a regular LCD where you just send it raster images; the driving waveforms etc. which are needed to do effects like this are abstracted away, and the details are kept secret.
- TeMPOraL 9y agoAny examples? I've only played with Waveshare screens/drivers a little, but I'm pretty sure I saw the LUTs defining voltage levels and times on the "user side", e.g. within the examples code. And from a YT video that shown how to drive those screens at 3FPS (didn't try it myself yet), I assume those are the actual LUTs that convert abstractions into voltage control.
