16 years agoHi, I am working with the NEEK, too, but I am using NIOS for the programming. From my NIOS-Core I have a connection to the output VHDL-Module of this example: http://www.alteraforum.com/forum/showthread.php?t=6118 Perhaps you look into it. See the File in neek_rgb_vga, that is the Block that I use to connect my ClockedVideoOutput from the NIOS to the VGA-Adapter (this code is 10Bit wide and has 1024x768Pixel, but perhaps you adept it).
The main timing problem on the NEEK seems to be the connection over the MAX II. You will need a Block like the neek_rgb_vga or VideoSyncGenerator (see altera\*ver*\ip\altera\sopc_builder_ip\altera_avalon_video_sync_generator) to connect to the LCD, also the clk must be 3*LCD- or VGA-Clock. The clock and other settings for VGA can be found in the MTDB Manual Table 4.4, 4.5 Page 21. The Data of the LCD is on Page 16 and ff. Perhaps this helps you a little bit, good luck!
