Hello All!
I have been playing around with CEC for a little while and in every implementation it has worked great for me.? However, recently I was asked if there was a way to test CEC and I got a little stumped because it's always just worked for me.?
There are multiple ways of testing RS232 communication to ensure the commands are getting to the device.? For instance, if I jumper the Tx & Rx then I can get feedback to ensure the cable works and the command is being sent.? It's also possible to pick up a DB9 tester to verify signals as well.? I've used RS232 a lot so I am familiar with many tricks to prove RS232 is working.
So my question is: What about CEC?? It's not like we can (easily) jumper HDMI ends to verify transmission. Is there a means to verify CEC commands are being transmitted via HDMI and received by the device?? Is there a device which can be used to test the HDMI cable?? How do you test CEC?
