Use level shifters, both uni and bidirectional are available.
I've found them here for ~$3, so you'd get almost 3 for that amount.
This sounds like a typical 'memory mapped peripheral'; the TRS writing bytes to a specific address or set of addresses to instruct the DVI to do something, passing out bytes for disk and reading bytes back.
I agree. I might have biten off more than I can chew.hippy wrote: ↑Sat Feb 10, 2018 11:44 amThis sounds like a typical 'memory mapped peripheral'; ..
What protocol is used in doing that is anyone's guess .. whether simplistic or complicated. You may only be interested in video but you might have to cater for much more in order to get the TRS to recognise that DVI is there and to handle whatever it might do once it has detected it is.
You are right. But a video-out device has been discussed in the community for years now. I just want to start it. Even though it's way above of my technical abilities. Maybe, smarter people will take over. At least, will have done something, even if it turnes out to be useless.
I suppose it depends on whether you are trying to clone or emulate that DVI device or simply using the Pi as a means to get data out of the TRS under user program control.
