There’s a new guide in the Adafruit Learning System from Jeff Epler:
The new RP2040 microcontroller from Raspberry Pi Foundation has a powerful feature: the PIO module, a sort of accelerated I/O processor.
One advantage of driving your NeoPixel LEDs this way is that less time is spent actually sending the pixel data to the LEDs—It is about 7.5x faster to show() your NeoPixels with the parallel method. Depending on your project, having parallel strips as opposed to chained strips can also make for better wiring.
Check out the guide now and learn more about the Programmable Input/Output (PIO) controller of the Raspberry Pi Pico. What project will the Pico’s PIO module will help you make? Let us know in the comments.
