Скачать или смотреть A Tiny Raspberry Pi Zero Controlling 14,400 LEDs

This video shows how a tiny Raspberry Pi Zero W drives a large DIY video LED display made of 14,400 WS2812B addressable RGB LEDs.

Even much more powerful computers struggle to control a display of this size in software while maintaining a 60 Hz refresh rate.

In this setup, the Raspberry Pi connects to the Pixblasters MS1 Video LED Controller, which appears to the Pi as a standard monitor.

Video is transmitted over a regular video cable, while all LED timing and processing is handled entirely by the Pixblasters MS1.

Multiple controllers can be chained together, enabling displays with hundreds of thousands of LEDs.

Because the Raspberry Pi sees the entire LED wall as a monitor, it can drive even massive installations without consuming additional computing resources.
