Update to HDMI test project.

Hi, I've finally got around to working out how colour on the Zedboard's HDMI transmitter works.

You can find a sample project that displays red/black/green/white/blue colour bars on my wiki, at http://hamsterworks.co.nz/mediawiki/index.php/Zedboard_HDMI_v2.

Hope it helps somebody...

Cheers

Just added one more update. 1080p now works, with the fabric running at 150MHz - so using true DDR. The test pattern has been change from colour bars to a sort of true-colour display.

It is also using cascaded DSP blocks, to improve timing and reduce resource usage.

The full project for both 720p and 1080p can be downloaded at http://hamsterworks.co.nz/mediawiki/index.php/Zedboard_VGA_HDMI.

The HDMI clock timing for the 1080p version is most probably a little flakey - I wouldn't be surprised if further tweaking is needed.
