Right now, I’m working on what might be the series’ pièce de résistance — a reimagining of Lemmings, a blockbuster game from the early 1990s (above).
The current post looks at the graphics interface using a 2.8” IPS display from Newhaven (NHD-2.8-240320AF-CSXP-F). The device comes with an embedded ST7789Vi controller.
I covered the ST7789 protocol and the 16-bit RGB565 pixel format in an earlier article; the core pixel-pushing logic — which operates on hardware I/O lines via memory-mapped registers

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
