How to support the TFT LCD in Nios II

Hey,

My guess is that you will probably need to change the linux system design that Microtronix provides in order to interface with custom hardware. Unfortunately they do not provide a source for the design, only a compiled version. Then you will probably need to write a linux framebuffer driver to support that hardware. When I researched the topic of writing linux video drivers I found very little useful information. This site might be useful: http://www.linuxforum.net/docnew/printthre...n=705&type=post (http://www.linuxforum.net/docnew/printthread.php?cat=&board=new&main=705&type=post)

And then you will need to recompile some small variant of X in order to get graphics. http://www.microwindows.org/ (http://www.microwindows.org/) might be a good choice.

Adding a video display was and idea I had in mind too, and it probably wouldn't bee too hard to implement some sort of a vga driver in the fpga and write a driver for it then use a regular pc monitor for display. But really, in most cases an embedded system would not need a video display.

I think adding video support to nios linux will mean a lot of work, but it might be fun.
