Raspberry Pi Pico Achieves 100 Mbit/s Ethernet Through Software Bit-Banging
By

Crisped on the outside, thoughtful enough on the inside.
Summary
Developer Steve Markgraf has successfully implemented 100 Mbit/s Fast Ethernet on the Raspberry Pi Pico using only software and PIO (Programmable I/O), building on previous work from three years ago when another developer achieved 10 Mbit/s Ethernet on the same hardware. This represents a significant technical achievement in bit-banging high-speed networking protocols on low-cost microcontroller hardware.
Key quotes
· 3 pulledThree years after the popular Pico-10BASE-T experiment and following bit-banged USB in 2023, developer Steve Markgraf now bit-bangs 100 Mbit/s Fast Ethernet on the Raspberry Pi Pico using only software and PIO.
Three years ago, @kingyoPiyo's Pico-10BASE-T project drew wide attention right here on Elektor for implementing 10 Mbit/s Ethernet on the Raspberry Pi Pico using just a few resistors.
