Isolated LAN Ethernet Port
The IoT Discovery Gateway has a downstream port intended to provide access to Ethernet-equipped industrial equipment such as Programmable Logic Controllers (PLCs). The downstream port is implemented using a Wiznet W5500 SPI-to-Ethernet bridge and uses the W5500’s integrated PHY.
The W5500 is accessed using the imp005’s hardware.spi0 peripheral and the active-low chip select (nCS) pin dedicated to hardware.spi0. The W5500 interrupt and reset pins are connected to imp005 GPIO for additional control. SPI communications are limited to 8MHz.
