This page brainstorms about possibilities for graphical display functionality


what displays we've got now is:


what we'll have for sure:

Note that developers are strongly against these.

Reasons:

Regarding Data Display

I would like to suggest using a small portable TV that operates on 12v. This also opens up the use of a VCR in the car to visually record data.

Circuit Cellar has several articles, one uses a micro to generate TV sync while also doing real processing, free compiler for this, another article by Fred Eady, duplicates an LCD, uses a pic, 5370xxxOSD IC, maybe the little Atmel micro could replace the PIC.

If interested, I could post article details to files,

It is definitely possible (an ARM and an offtheshelf video chip can be put on a PCB) but I'd say first task is to make OtherTuningSoftware work on PDA. Make a PDA (the above suggestion is effectively making a PDA) only after that (it seems that competition is tough there, hard to compete unless millions of units can be sold). All the displays (CRT or safe types) I know are more expensive than a full-featured PDA.


Marcel,

Sorry I write or explain what trying to say so poorly. Qne of the articles simply details how to make the TV display a picture like an LCD, LCD EMULATION.

(I think I understand, and it seems it is effectively useless until we have a PDA display app).

It effectively replaces an LCD module, Just plug into what would normally drive an LCD subsystem.

(just plug it in wouldn't be useful, even if it worked that way. It needs to be defined what should be displayed and how!)

You can then record it on VCR, camcorder etc.

Small TV's can be bought here for less than $20.00.

(OK, that unit price is compelling, but the development costs are not).

Nothing to do with PDA, just another adaptive display, several area flea markets sell a 5x7 color video display for less than $70.

(yes, it has a lot to do with PDAs! We cannot use that for anything before we have a working app, which will surely work on a PDA next. After we have the display code - might be just 3 days if someone really sits down - we could think if we put the 8000 Euro worth of development effort into driving a CRT or if we can find something more useful.)


A list of graphical modules

I think this can be somewhat cheaper if we buy many.

It cannot compete with Nintendo prices, but even a 320x240 can fit our budget.

Could someone look up in datasheet how hard to drive these ?
