Hi, im new to vhdl and i need to display data(real time/continuous) in a form of a plot/graph. i dont really know how to display stuff on the vga but atleast i can manipulate the colours, draw block, grid, etc. i just dont know how exactly do i have to go about implementing this.

This is how the code should work...
1. i read an analog value, then convert it to digital 8 bit word (this part i think is sorted).
2. then the 8 bit word is read by the fpga, maybe converting it to an integer.
3. display integer values on the vga screen vs time (in intervals of 1s).

Im confused, pls help me guys.

im using cyclone II DE1 board. example codes will be highly appreciated
