Samsung SSSP Controller
Even Samsung Digital Signage SSSP designed for 24/7/365, sometimes it can be freeze when running for long time. Samsung SSSP has protocol for able to remote the TV via LAN, it’s called SDP protocol. At the first release i was develop it using MCU ATMEGA2560 and W5100 ethernet chip. After deploying for several times, it has another problem: board on the TV freeze so can’t remotely turn on and turn off via LAN. Then i added SSR to cut TV power. Nice and well done, TV can be hard reset via remote. This helpful when the TV on unattended location.
The display show internet status, IP address and TV status. Using MQTT for control it.
