Do you have a PiGRRL or other Raspberry Pi-based portable creation? Do you enjoy fast games like Sonic the Hedgehog, but the performance of the SPI TFT display left you wanting?
Jukka Jylänki’s fbcp-ili9341 is a high-performance alternative to kernel modules, fbcp or our own userspace PiTFT software. They’ve tackled the speed issue from every angle, optimizing screen updates and doing SPI DMA things in userspace code that I had no idea were even possible…60 frames/second updates can be achieved and latency is better even than some HDMI screens.
There are fine-tuning options for every Pi and quite a few different screen types. While a Pi Zero might not keep up with the fastest games, this is the best shot there is. Eking out the very best performance takes some work…thankfully the detailed documentation is every bit as impressive as the code!

Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
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.
