Because I needed a vga driver for one of my own projects I have rewritten the vga controller code in the hardware section of the the code library.Basically i have altered it to make more efficient use of the memory available in the low cost acex fpga range and it can now more even better use of it by being built either a three colour display or a single(monochrome) display.This allows a resolution of 256x256 in the smallest available acex device in monchrome mode on a standard vga diplay,it will go upto 512 x512 in the larger devices which have more built in memory.Once i have finished the testing i'll post the modified code.
To be able to use this code you do need to know how to drive the altera design tools to allow you to fit it into the fpga but the goos news is that it will compile under the older altera tool sets.I am in the process of writting a datasheet for it.
