To display a square on monitor ( Verilog vga Basys 2 board )

If I use clock divider,will that be alright? For ex- reg [23:0] q; always @(posedge clk or posedge reset) begin if(reset) q<=1; else q <= q+1; end wire clk381; assign clk381 = q[16]; // clock of 381.47 Hz or 2.62 ms and then use this clock in location counter?

To display a square on monitor ( Verilog vga Basys 2 board )

I have made certain changes in code. And regarding next_?_location, I want my square to move across two horizontal ends automatically without any change in y coordinates and thus I have now removed that next_y_location counter.This movement could be done in regular intervals to provide a steady...

To display a square on monitor ( Verilog vga Basys 2 board )

So I have written this code which moves a square automatically on vga screen. Before simulating this I would like to know if there are any mistakes I have committed in writing the logic of this code. Any help would be much appreciated. reg [10:0] x_location_reg,y_location_reg; reg [10:0]...

Well I am familiar with cloack enables. What I don't understand in this code are those so many if-else statements. I mean what exactly is the logic?

To display a square on monitor ( Verilog vga Basys 2 board )

Okay,thank you for the suggestion regarding debouncing. But due to time constraints I dropped that push button idea. Now I just want to bounce the ball automatically on vga screen. So I looked upon this VHDL code for reference, but I know verilog and not much about VHDL. Also, I am not able to...

To display a square on monitor ( Verilog vga Basys 2 board )

Thank you Mr. Fibble. The code is working now. always @(posedge clk) if(~video_on) coloroutput <= 0; else begin if((pixel_x > sq_x_l && pixel_x < sq_x_r) && (pixel_y > sq_y_t && pixel_y < sq_y_b )) coloroutput[7:5] <= 3'b111; else coloroutput[7:0] <= 8'b00000000; end

To display a square on monitor ( Verilog vga Basys 2 board )

As I wish a red colored square, therefore, I assigned these 3 MSBs as 1. And regarding this statement "if((pixel_x > sq_x_l && pixel_x < sq_x_r) && (pixel_y > sq_y_t && pixel_y < sq_y_b ))" ,when I change y coordinates,changes in vertical coordinates of square are visible but the same is not...

Sure ! Made the desired changes and the output waveforms now are the same as you posted earlier. But the problem is that as I start the program, my monitor displays ' Out of range' ! Why is it so?? Help !
