Ethernet to SPI to Ethernet transceiver #Communications #Development

What if you have a computer with SPI but no Ethernet capability – how would you generate SPI communications from incoming and outgoing Ethernet traffic? Ivan’s blog explores how to do this with logic circuits.

My discrete computer lacks two major things: sound and network. The project I describe here is the first step to making it capable of network communication. I don’t touch the computer itself now, but instead build a transceiver which converts a 10BASE-T Ethernet signal to SPI and back. I use an STM32 MCU to test my transceiver for now. In the future I plan to connect the transceiver to the discrete computer.

Check out the development process and implementation in the post here.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
