Hi,
I am thinking of integrating a TVT-KVGA (UK) controller in to one of my PICAXE projects using an 18X PICAXE. (I found the place from another post.) Has anyone had any experience with this company and their products. Not just how well they work with picaxe but experience from buying from that company(Obviously they speak german and I don't so how easy is it to buy from them?).
(Shipping to UK)

Thanks,
Mike

I looked at buying one of those they did respond to e-mails.

The shareware mono one with keyboard looks good and is quite cheap.

I eventually went for one of these for a simple text display it works very well. In fact I've just bought another three chips!

http://www.speechchips.com/shop/item.aspx?itemid=5

Run the 18X at 8mhz and use T4800 and you drive it directly with your data. Very easy and minimal components.

Pic here using one of these cheap in car RCA 640x480 reversing monitors.

Hi,

So did you buy from speechchips or tvterminal?
Please could you show me some sample code for the chip (e.g. the serout commands).
Also, do you know any other places that do chip for bigger screens like a TV, (or will that chip work with TV?)
thanks,
Mike

I bought from speechips as I liked the 8 pin minimal component solution.

The speechips SV2000 outputs a standard RCA 75ohm 1V composite video signal, any RCA compatible monitor will work. (yellow plugs and sockets) Most TV's have them nowadays.

Here is a pic of it driving a standard telly via yellow video in socket.

www.solarvan.co.uk/bms/VideoDisplay01.jpg

Code: 
setfreq m8				;Setfreq CPU Freq to 8mhz
serout Video,T4800,(27,67," BMS Master V96 By Peter Perkins")	;Splash Screen Video Display
27 & 67 are ascii control codes to Clear the screen and return cursor to home position 0,0.

I suggest you download the SV2000 document and have a look at it.

It can display the full extended range of ASCII characters but no pretty graphs etc unless you can make them out of ascii charcters.

Now I did do some crude code to allow it to display giant numerals 0-9. But I never used it in the end.

A couple of youtube videos showing it (SV2000) in action in my BMS project

I would encourage you to try the KVGA or the other one from that firm as I would like to see how you get on as I have considered it for my next project. These were just my results with the SV2000.

More and more offerings - this can only be good! I looked into this a while back and wrote off to the KVGA people in Germany but there were issues with exporting from the EU to Australia. But that probably doesn't apply to the UK. Their product is really good.

I ended up going with the pocketerm http://www.brielcomputers.com/wik/index.php?title=PockeTerm which gives a 80x25 ascii character display on any VGA monitor. It uses the propeller chip and I hacked some of the code to add some different codes as well as VT100 and got it to the point of playing Pacman. The propeller is changing all the time and I think graphics can be done as well. (I only needed ascii text for my applications).

The propeller can drive VGA or TV or both.

Re "What 'attack warnings'?" - I got it too - a warning on one of those links that this site was about to attack my computer. So I haven't seen the picture on that link. Not even 100% sure which link it was (the solarvan one I think) and not game to try again. It would be great to see a photo of this in action though...

Ah. I see why I missed it. I often surf with my IE security settings on High. It saves me loads of hassle with flash adverts and other stuff (like this warning for example). Visit the picture link with your settings high and you get only a picture :)

RE attack warning. Please click ignore. I/my host got hacked months ago and it's almost impossible to get off the google list once they find something on the server!!! I spoke to support etc all to no avail. I deleted my complete site and re-uploaded it months ago :rolleyes: It's really annoying I think the only way for me to get rid of it is change host completely!!

I think I have finally sorted it but will take a few days before google clasifies the site. Deleted one more suspect file which had been dropped into my root folder!!! It is safe to click the ignore warning button. If I embed the pictures it bypasses the warning anyway.
