Network Messages Managed by the Display Device
Network Messages managed by the Display Device
The protocol can be implemented on inexpensive micro controllers such as the Atmel ATmega328. Because of this the work required on the display device is very limited.
Each display device must have an Ethernet connection. To ensure zero configurations the device should be able to get an IP address from a DHCP server.
The display device must listen to messages on 2 different ports:
- One port for broadcasted messages that are shared by all devices on the network.
- One port for unicast messages where the pixels to be displayed are received and where setup parameters local to the device are read and written.
