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 Python library for interfacing with DLN2 USB-to-SPI adapters with a spidev-compatible API. This package allows existing Python code written for py-spidev to work with DLN2 devices with minimal ...

SPI flash devices, also known as DataFlash are commonly found in embedded products, to store firmware, microcode or configuration parameters. PySpiFlash comes with several pure Python drivers for ...

You might already have the hardware on hand to easily interface I2C and SPI devices with Python scripts on your computer. The board seen above is an FT-2232 breakout board. These chips are often used ...
