NEW GUIDE: ulab: Crunch numbers fast in #CircuitPython #AdafruitLearningSystem #ulab @Adafruit
A new guide in the Adafruit Learning System: ulab: Crunch Numbers fast in CircuitPython. ulab (pronounced “micro lab”) lets you perform number crunching tasks in CircuitPython more quickly, often around 10x as fast.
ulab makes things faster by operating on entire arrays of values in one operation. For example, when you have two numbersa and b, a+b adds them together, returning a new number. When you have two ulab arraysa and b, a+b adds the corresponding numbers in a to the corresponding numbers in b, returning a new array. Want to double every number in an array? That’s a*2. Compute its sine? ulab.vector.sin(a). It also has special versions of functions like sum that act on a whole array and return a single number. Documentation for all functions in ulab are on readthedocs.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
