Github Files

Hardware Setup

Connect the VGA display to the VGA Port on the Nexys4 Board

Part 1 - Configuring FPGA

Create a new project named VGAball
Create a new VHDL source file 'vga_sync.vhd' and insert the code
Create a new VHDL source file 'ball.vhd' and insert the code
Create a new VHDL source file 'hexcalc.vhd' and insert the code
Create a new XDC constraint file 'hexcalc.xdc' and insert the code
Run the Generate Bitstream (it will also run Synthesis and Implemented Design if out-of-date)
Open the Hardware Manager and connect the Nexys 4 DDR board.
Program the device with the file 'vga_top.bit'

Part 2 - Changes

1. To change the size of the ball, change the integer size of the ball in 'ball.vhd' as shown to the right.

2. To change the color of the ball, set the value of the specified color you want to a '1' and change the other values of the colors to 'NOT ball_on' in 'ball.vhd' as shown to the right

3. To change the shape of the ball from a square to a circle, edit the 'bdraw process' of the code in 'ball.vhd' to the code shown to the right.

4. To introduce a new signal ball_x_motion so the ball can move both horizontally and vertically and bounce off the left and right walls, edit the 'mball process' of the code in 'ball.vhd' to the code shown to the right.
