EDK-VGA interface through SPARTAN 3e starter kit using EDK 9.2i

[vgs]

Hai everybody,

Could anyone please help me to display an image in the VGA port using Spartan 3e starter kit using EDK 9.2i.

Kindly help me
Thanks in advance

You can search the archive. This exact same question comes up every now and then. Case in point, I see one on page 1 in this forum:

And why do you think that is?

Not really. I have my own things to do. I am however perfectly happy to help people that show their own work so far, and can point to specific problems they are encountering.

So ... what have you done so far, and where specifically are you stuck? If you have no clue whatsoever where to start (perfectly legit situation) then I suggest googling around and reading for a day or two. Or ask your teacher/prof for help.

Thank you for your reply.
I'm doing an object recognition system based on Neural Network using EDK.
I've completed the Neural Network section and added it as a custom IP in the Microblaze structure.The output of recognition process is 00,01,10 and 11 for the four different shapes.As a demo I need to display an image corresponding to these four shapes through the VGA port.For this, I searched in google and I found out that, there is an inbuilt IP called "xps_tft" in the higher versions of edk for this purpose.I'm using EDK 9.2i,so is there any probability to create an IP using the 'Create or Import peripheral wizard' having the same functionality as that of that IP .

And that is what you should have posted the first time.

You have now transformed the problem from "help me do my homework, I am too lazy to type more, plz help" to "how do I import a newed specific IP from a recent version of the EDK to EDK 9.2i.

That's more likely to get you an answer. Personally I have only imported older IP's to be used in a project with a newer EDK, not the other way around. I found that process to be annoying enough already, and I suspect that exporting IP from a newer EDK and using it in a project on an older EDK is going to be even more annoying.

You could try to create the IP in the new EDK with as old a bus standard as possible (so no AXI) and then try and import it. I'd expect you'd have to do some hand editing of the .MHS file. At least that was my experience with that sort of thing.

hi,
please help me if you have time.
I'm trying to add a custom IP to the EDK.Its just a comparison program, i.e., to compare the input with four values stored as four different signals and if the input is similar to any one of the input, then give the output as 00 or 01 or 10 or 11.
this is the Vhdl program for that:
library ieee;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;


entity network is
port (clk:in std_logic;
input:in std_logic_vector(31 downto 0);
outputut std_logic_vector(1 downto 0));
end network;

architecture Behavioral of network is
signal t,r,c,s:std_logic_vector(31 downto 0);

begin
process(clk)

begin
s<="11111111000000001010101001010101";
t<="11111011111000000000100101100101";

r<="11111100000000000101011010101010";

c<="11101111001100000100011010011010";

if (clk'event and clk = '1') then


if(input=s) then
output<="00";


elsif(input=t) then
output<="01";

elsif(input=r) then
output<="10";

elsif(input=c) then
output<="11";
end if;
end if;

end process;
end Behavioral;



This program is added as an IP to the EDK with the name "my_network" using "create or import peripheral wizard" using "read/write FIFO".

After adding it as an IP, inorder to input the value and obtain the output,I wrote the application in SDK.

This is the code I've writtn in SDK:

#include "xparameters.h"

#include "xbasic_types.h"

#include "xstatus.h"

#include "my_network.h"



Xuint32 *baseaddr_p = (Xuint32 *)XPAR_MY_NETWORK_0_BASEADDR;



int main (void)

{

Xuint32 i;

Xuint32 temp,check;

Xuint32 baseaddr;

// Clear the screen

xil_printf("%c[2J",27);



// Check that the peripheral exists

XASSERT_NONVOID(baseaddr_p != XNULL);

baseaddr = (Xuint32) baseaddr_p;

xil_printf("Recognition Test\n\r");





// Reset read and write packet FIFOs to initial state

MY_NETWORK_mResetWriteFIFO(baseaddr);

MY_NETWORK_mResetReadFIFO(baseaddr);



// Push data to write packet FIFO



//temp=0xFC0056AA; //these are the four values which are given as input

temp=0xEF30469A;

//temp=0xfF00AA55;

//temp=0xFBE00965;





MY_NETWORK_mWriteToFIFO(baseaddr,0, temp);



xil_printf("Wrote: 0x%08x \n\r", temp);

// pop data out from read packet FIFO



temp = MY_NETWORK_mReadFromFIFO(baseaddr,0);

xil_printf("Read: 0x%08x \n\r", temp);

if (temp==02)

xil_printf("The given shape is Rectangle\n\r");



else if (temp==00)

xil_printf("The given shape is Square\n\r");



else if (temp==01)

xil_printf("The given shape is triangle\n\r");



else if (temp==03)

xil_printf("The given shape is circle\n\r");



// Reset the read and write FIFOs

MY_NETWORK_mResetWriteFIFO(baseaddr);

MY_NETWORK_mResetReadFIFO(baseaddr);



xil_printf("End of test\n\n\r");

}


but the problem is that, for all the values I'm getting only 00 as the output.

Can you please help me.Sorry if I'm disturbing you in your busy schedule.

Thanks and Regards
