While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

A very simple threaded and thread-safe class to control a string of ws2812 LED strips using SPI interfaces on Raspberry Pi/Orange Pi/etc. single board computers (SBCs) running Linux. An activated SPI ...
