DE2 - video to VGA in VHDL

Have you solved the prolem? do you have vhdl code for DE2 that configures the board for PAL in VGA out?

Thanks,

hello,

Important point to understand my concerns, I am European (vhdl and pal).

I am using a DE2 board and I wanted to start transferring the video input to VGA output.

For this I used the program DE2_TV cdrom.

But I get nothing out!

In fact I get a picture in case I go back to NTSC but the image contains only saturated RGB colors, very ugly !

I was not able to measure the frequency on pin 14 of the VGA :oops:

In addition, the codes are in verilog and I usually work in vhdl.

In a second step I decided to use DE2_Default (work on an image to start) included on the CDROM, but I do not know how to get from an image file. Hex?

and the code is still in verilog ...

My questions:

Is there a version of vhdl DE2_TV and works in PAL and can you explain the behaviors and problems I encounter?

Why the project is there no file VGA_Param.h when he is in DE2_Default ?

Maybe he should copy the folder VGA_controller?

Is there a program to convert an image in hex​​ ?

Where is the documentation of his examples ?

And do you know if there is a version of vhdl examples?

If there are no equivalent programs in vhdl I can include my code in vhdl in the original project in verilog?

Can you tell me how (the method) and where in the verilog code I have to do :confused:

I wish the final apply filters on a simple image you links to examples of this type with the DE2 board and vhdl ?

Thank you in advance for your answers.
