Microchip MCP23S17 SPI GPIO expander connected over the hardware HSPI module.

TCP Listener configured on port 33333. Send it a 2 byte command to turn the outputs on or off.

Code: Select all

echo -ne '\xFF\xFF' | nc 192.168.5.1 33333

Could easily be expanded to a project controlling relays, triacs, etc.
