SPI ethernet device (lesson)

introduction

SPI is a synchronous serial interconnect with a protocol definition used to connect to computer devices (see SPI devices.)

We will first study some code examples to see how others have written device drivers that are used in

• computers, such as the raspberry pi, and
• micro controllers such as ESP32 and the pico,
• and research available devices.

aim

Students are to add an ethernet adapter to a pi W

basic outcome

• research links to code examples
• understanding of SPI
• a functioning ethernet port on a Pi W.

requirements

• one SPI network adapter
• one pi zero W

advanced outcome

Students are to explore attaching an SPI ethernet carrier to a pico or pico W.
