VGA controller

From: damir on 7 Dec 2005 09:37 I'm looking for simple VGA (XGA up to 800x600) controller for displaying simple images on the LCD pannel - any suggestion for available ASIC (LCD controller) or FPGA (VHDL core) design will do. Thanks, Damir

From: damir on 7 Dec 2005 10:17 I've found reference design from Xess for their Xilinx boards - it's for standard VGA, but as you've said - translation for digital flat pannel interface shouldn't be a problem.

From: damir on 8 Dec 2005 04:14 Currently I'm looking only in 800x480 resolution with (if possible) 18-bit color (16 bit is also ok) and flat-panel digital RGB interface.
