LittlevGL is an open source graphics library for generating lovely graphical user interfaces (buttons, sliders, graphs and so forth) on microcontrollers.
We’ve made an Arduino library — Adafruit_LvGL_Glue — to simplify the task of sticking LittlevGL on many Adafruit displays: PyPortal, TFT FeatherWings, and most other Adafruit devices with (or connected to) a color TFT or OLED screen, using fast DMA transfers when possible. Touchscreens can be used for responsive interfaces. For non-touch displays, LittlevGL can still be useful for its nice graphing and text display capabilities. Mostly, though, we think this will shine on Adafruit PyPortal devices, with their extra fast displays and touch sensitivity.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
