Colour TV Display IC

Some time ago I posted a question on here, if anyone would find a use for a TV display IC, and got quite a few replies saying yes, if it were available. Well now it is available, at least one version is so far - 1000 chars max, 50 columns, 8 colours, 21 lines, I can't put a picture up here (can I?) but here's a link:

Works directly with PAL TVs via a SCART input. Can be fed into composite input TVs (PAL or NTSC) by using a modulator IC. Useful alternative to small LCD displays. Data is fed in through a single wire serial input. Selectable baud rate.

It's mainly intended for displaying bar graphs and data as it's collected, but has plenty of other uses.

If the look of the IC interests you, there is a full datasheet

Please contact me with any questions you may have. I check my hotmail account most, its gmcarnell [- a t -] hotmail.com

Can the PAL1000 display on a PC monitor?

No, the timings are totally different. I have a design for a VGA board, but I've got so many other things to do first...

Do you have an old portable TV with a SCART socket lying about forgotten - they're ideal.

TV display IC

Not sure if anyone here is interested, but I have been working on the TV chip some more and have been listing it on Ebay for a while and supplying a few. The latest listing is here
This listing is only up for a few more days.
Next thing is a kit and also a fully made up version in an ABS box for people who just want to plug it in and use it.

New IC and PCBs

New IC with differing pin-out to fit onto PCBs which are now also available.

New data sheet here

Nice looking graphics for it's purpose, well done.

However, with all those spare pins, i'd like to see COMPOSITE coming out of 1 of them, afterall most of us dont have a bunch of scart tv/monitors or RGB monitors available, yet we all have access to regular composite monitors.

Just my 2cents :)

Keep us posted of upgrades.

So would I. Unfortunately, composite video needs an encoder IC to add the colour burst signal at the start of each line. Can be done, I've forgotten the exact number of the IC now, it handles NTSC and PAL.

NTSC encoding is not as complex as PAL, I could (one day when I have a lot of spare time) add an NTSC composite output but not PAL. That would definitely need another chip.
