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 hands-on tutorial that walks through building simple CRUD APIs with several popular frameworks. Each framework lives in its own sub-folder and is demonstrated through a shared Next.js UI.

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 ...
