IPC video IN

[paxtonix]

Hi all.

New to community so don't go rough on me

Recently I've come across a video on youtube, about "future" technologies.

mondeo with convers+ is also included in 3:30min of video.

In 4:40min of video we can see that passanger is operating winXP on convers+ dash .
I fully understand it is a video stream from the pc , stored in the trunk, that can be saw earlier in video.

What about if instead ,a whole machinery in trunk, implement a small (e.g. rapsberry PI type ) PC and stream the video into C+ like it's done in the movie ?

Please , any one can help over it ?

Any one can't help me with this ?

Don't get any word they are talking about, but they may use a complete different firmware on the Convers+.
First of all, this is "only" a small computer, with CPU, RAM, Flash, power supply and IO-Interfaces. One is the display, which is driven by a standard LCD-Driver chip. So if one would be able to compile a kernel for the CPU architecture and write all the IO drivers, it may be possible to run other software on it as well. But i would doubt if the CPU has enough power and RAM to drive such an OS.

When you read Ursadon's posts about the Convers+ internals you find that there is a video buffer somewhere in the RAM and he was able to read a "screenshot" via CAN from there. And it may be possible the other way. BUT, the transmittion by CAN is far to slow to use it as an monitor. The MS-CAN is limited to somewhat 30 kb/s transmition rate, so no chance to transmitt any video.

I would like to write small data imges to videomemory from my own device via mscan. Im searching some informtion how to get access to this memory from can bus. I understand that its possible without putting convers to sbl mode.

I was thinking more like using only the display HW, or a way to stream video directly to c+ without using its graphic procesor.

I understood you, but even if you x-out every functionality, write an own program which runs exclusively on the MAC7116, just using the graphics, the question remains how to transfer data from (whatever in whichever format to the board via which channel.

The display has a physical resolution of 800x400 pixels and the LCD-Driver-Chip (EPSON S2D13A05F00A1) is capable of 256 colors from a RGB palette. Even compressed (and i don't know if the MAC could handle realtime decompression) with only 16 or 20 fps you will end up at 80-120kb/s. The CAN of the IPC can only handle 32 kb/s max.

So how would you transfer the videodata?

[Go4IT]

After digging deeper into the electronic components of the IPC if found that the EPSON LCD controller has the capability for Picture-in-Picture and also overlay functionality. So in theory it would be possible to add a window with an external video source. But without the needed components and of course the needed software support it would be hardly done anyway.

MM-CAN and IPC in "special mode" .. we will get there for sure!
