Specifically, a new page, “Minimizing Redraw Flicker,” has been added to get cleaner updates on many GFX-compatible displays. For example, when showing live updates from a sensor, rather than clearing the whole screen and printing new numbers, there are ways to have new values overwrite the old ones in-place. This gives projects a more polished appearance with just a little extra effort. Nothing actually new in the library, these techniques just haven’t been well documented before.
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.
