Using serial (RS232) connection to control TV
Has anyone used an RS232 connection to control a TV? I am fortunate enough that the TV I am going to use offers full control of all functions via a serial port connection. The manual for the TV provides all details for the connection, plus all the commands. I have done some tests and the control through the Hdmi port doesn’t work reliably enough so RS232 seems like a good option. I don’t have enough programming experience to pull off making a module so I was hoping someone else has at least tried this.
@rubberduck that should be totally doable with python. And the mirror and python can be done. There are several module that use python scripts. Are you wanting to just turn the tv on and off?
your tv will need to be able to restart on the same hdmi port you have your video from your pi feeding into. just a thought.
If you want to just keep the tv on, but blacken the screen, your tv might have a screen saver or something … some do.
@kayakbabe if you can get it working with python, I’m thinking maybe the python package pyserial would be enought.
@kayakbabe you can do serial i/o w node very easily
the serialCommander npm lib handles the send, wait for response ( of choices)…
@sdetweil even better! Then it’ll run on many more operating systems!
