To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious ...
[Tobias] goes through the usual examples: setting the Pi up as a serial device for hacking and code cracking in a terminal, as an Ethernet device to give the Pi Zero networking capabilities ...
A shared channel that transmits data one bit after the other over a single wire or fiber; for example, Ethernet uses a serial bus architecture. The I/O bus from the CPU to the peripherals is a ...
