Custom Display Drivers Explained: LVGL 9.4 Deep Dive

Running a full UI library like LVGL on a 32x32 LED matrix might seem like overkill, but it's the perfect way to master display drivers. In this video, I demonstrate how to port LVGL 9.4 to the Pimoroni Cosmic Unicorn, writing a custom flush callback to map the draw buffer directly to the LED driver.
