Project description

Using W7500 as a SPI-to-Ethernet Bridge An open-source project, w7500-spi2eth, demonstrates a method for configuring the WIZnet W7500 chip to operate as a SPI slave that handles Ethernet communication. Instead of running as a standalone MCU that manages network stacks internally, the W7500 in this setup is dedicated solely to Ethernet frame transmission and reception, based on commands received over SPI. Project Overview W7500 functions as an SPI slave, receiving commands from an external MCU Communicates using MACRAW socket mode, allowing direct handling of raw Ethernet frames Implemented…
