Raspberry Pi enthusiasts may be interested in a new Raspberry Pi display driver which has been created to produce high frame rates of up to 60 frames per second over an SPI bus. Watch the video below to learn more about the new Raspberry Pi display driver created by YouTube user “Jukka Jylänki”.
The new display driver supports a variety of Raspberry Pi mini PC systems including the 2, 3 and Zero W. “Ported my fbcp-ili9341 Raspberry Pi 3 Model B SPI LCD display driver to work on the ILI9486 based WaveShare 3.5″ (B) SpotPear 320x480 SPI display. This video is side by side comparison against the stock spi-bcm2835+fbtft+fbcp display driver set, running on Raspberry Pi 3 Model B.”
The Hackaday website explains a little more about the fast Raspberry Pi display drivers. “The techniques that let [juj] coax such frame rates out of a not-terribly-fast serial bus are explained in detail in the README’s How it Works section, but much of it boils down to the fact that it’s only sending changed pixels for each frame, instead of the full screen. This cuts out the transmission of about 50% of the pixels in each update when you’re playing a game like Quake, claims the author. There are other interesting performance tweaks as well, so be sure to check out the repo for all the details.”
