neek_rgb_vga.vhd is the VHDL module.The module accepts parallel RGB plus HV syncs with DATA Enable and a clock that is three (3) times the RGB pixel rate and outputs a NEEK VGA TDM data stream with syncs and enables. The ZIP contains a QuartusII Archive and will build a small test example of an instantiation of the "NEEK_RGB_VGA" module. Save off the SOF file before you rebuild so that you can see what it does, before you try to build it. *** Built with QuartusII v9.0 (sp1) and uses the Test Pattern Generator and Clocked Video Output from the Video IP to generate a video stream.
Hello,I have a cyclone III Starter Kit C25F324 and a hsmc quad video Bitec card. I am trying to use your design as a basis to do my own design. I compiled the project under quartusII and built it under niosII. The only modification I did is to remove the fifo in SoPC builder because the VIP did not support the "empty" signal of the avalon streaming interface. When running it under NIos II, the console keeps displaying : Error:Audio I2C ack access1 Error:Audio I2C ack access2 Error:Audio I2C ack access3 Do you have an idea how to correct this ? Thanks, Myriam
