App note from FTDI/Bridgetek demonstrating LED control over Ethernet. Link here (PDF)
In an increasingly connected world, more and more devices are going online. To enable online connectivity typically requires an MCU with Ethernet or Wi-Fi capabilities. To demonstrate the principle, this Application Note describes an implementation of a web server which allows for control of 2 WS2812 serial addressable LEDs. A web server is implemented on an FT90X device which when connected to a Local Area Network (LAN) allows a web browser to control the LEDs on an MM900EVxA board from a graphical web page.
