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.

In a similar vein. I’ve been writing an i2c screen driver for my Raspberry Pi (part of a much larger project). It uses the kernel i2c driver model, so it might make a useful example to someone.

Raspberry Pi's Python project path is split into six parts, beginning with three 'Explore' projects in which learners are introduced to new coding skills through guided tasks.
