Hi Dear Gentlemen,
I start long time ago this thread
https://www.edaboard.com/threads/173080/.
Now, I've sold this old thread and I've started a new project.
Because I repair some old TV in B&W from 1940 to 1970 with vaccum tube, I needed to build a video scaler from Color PAL 625 line to...
Hi Lahrach,
What kind of FPGA or KIT did you have?
I'm using NEXYS2 500.
I test the BIST and everything work fine.
Did you have some problem with the BIST or to load it on your card?
If you use some board from DIGILENT, you should know that they changer their soft few weeks ago.
I met some...
Re: help me to generate a refrence signal for an X-OR iC tes
Hi dear sir,
I really don't undersdtand what you want to do and to test.
You want to test XOR door? I'm right?
How many pins have your XOR circuit?
I suppose you need to test this kind of ICs without microcontroller.
Depending to...
Hi Dear Gentleman,
Your idea is a good idea.
My first idea was to build a simple test pattern generator to test my old B&W TV.
Watching TV with only B&W stripes during long period is not a very good idea because after long time, yours eyes are burned like TV CRT tube on the airport :D.
So...
Hi All,
This is the simulation of my design.
Everything work fine with right timing.
This code generate a complete black screen :D> this is just to test the synchro signal is ok.
Next step is to add black and white stripes and very later (don't forget I'm a newbee), make a complete real...
Hi Cyboman,
I stop to use ACTIVE HDL.
I only use XILINX ISE 11 webpack > be carefull because there is some version not complete.
It work fine> I post an other topic on edaboard because I need to repair olds TV black and white from the 40 and 50's with tube technology and I'm trying to built a...
Hi all,
My code run fine in NEXYS2 by driving the leds.
I just now need an monitor to test it in place of my oscilloscope.
Next step is to add code to make a proper video signal in place of signal to drive video monitor.

Hi Dear Sir,
Concerning your problem, I check this too long time for me.
I never find a way to solve it.
I spent too much time so I decide to move all I done to XILINX ISE WEBPACK.
I use in the same time ADEPT suite and now all is running.
I don't receive any reply concerning this problem...
Hi Farhada,
Thank you.
Today I'm trying to flash my NEXYS2 with XILINX ISE WEBPACK.
I spent a week to try to do it with ACTIVE HDL without any success.
Do you want I sent you my first code just to get afraid?
Have a nice day.

Hi Farhada,
This is exactly the form of the signal.
Have a look on this.
**broken link removed**
In this document, I' m interesting by the french standart.
In the Belgium standart, there is more visibles lines.
Here there is all the information concerning timing.
If you want, I can send...
Hi Farhada,
Thank you for your reply.
To test my TV, I want first check the possibility of my NEXYS2 to be able to generate and send a patter to my TV.
Next step is to realize a real time video scaler to test the great quality of these first HD TV in black and white standart.
For your...
Hi everybody,
I'm trying to make a video scaler using normal video signal PAL or SECAM 625 horizontal lignes at 50 frames per second and convert it to an other format but always for Cathodic TV.
In fact, my hobby is to repair very old TV using vaccum tubes technologie.
So, I repair actually...
Hi Dear Sir,
I 'd buyed the same NEXYS2 2 week ago and I have exactly the same problem> I have the same message.
Did someone find the solution?
Thanks for reply.
