Hey guys, I'm trying to drive a VFD that I found in an old blu-ray player. Apparently this uses a 3 line SPI interface (which makes no sense to me as there are 4 wires.)
I basically have a PCB with this screen on it, and a chip with CS16311EN on it (datasheet: http://links.r4-productions.co.uk/datasheet-CS16311EN) I don't speak any other language than english unfortunatly.
There is a collection of wires avalible to me, clearly labeled:
(on the 'data' plug as i'll call it) HOST_REST (no idea) GND (ground) IR_OUT (for the IR sensor) DATA_IN (part of the SPI?) DATA_OUT (part of the SPI?) CLK_SPI (spi clock) STB_SPI (part of the SPI?) KEY_INT (unknown)
(on the 'power' plug) +F1 (unknown) +F2 (unknown) VFIP (unknown) GND (ground) 5SB (unknown) +5V (5 volts) P_CTRL (unknown)
As you can see, I am providing the 5v and gnd to the 'power' plug (but dont have a clue what else to provide, will check the PSU for more info on that)
But I have no freakin idea where to start with this thing, I really want it to work as I am turning the blu-ray player into a HTPC (media centre pc). I can post pictures of the PCB if needed. A little kick in the right direction would be handy if you could guys.
P.S. The blu-ray player is not functional in an fashion and doesn't even power up, that is why I am doing this mod but also means I cannot 'sniff' and orginal data communation. Hope that isn't gonna cause issues.
