Hosting a website on an 8-bit microcontroller

The author builds a website server on an AVR64DD32 microcontroller, a cheaper alternative to the Atmega328 with better peripherals. Since standard Ethernet is too fast for the AVR's 12 MHz maximum peripheral clock speed, they use Serial Line Internet Protocol (SLIP) instead, an old networking standard that wraps packets in special byte sequences and runs over simple serial connections. The hardware requires minimal external components, though the author adds LEDs and a protection diode.
