arabic font on LCD

You can bit map them 1 at a time using the programmable characters.

The character-oriented LCD controllers only allow 8 custom characters, which would hardly be enough. You may have to just get a bit-mapped LCD.

I wonder if anyone goes to the trouble to make arabic-font LCDs. For that matter, is it possible to reduce that beautiful arabic script down to a dot-matrix?

Here's a good resource on the Arabic Alphabet. Looks like you'd need some good LCD resolution to display the script. Would a Roman alphabet transcription be acceptable? See

so I need a graphic display. I wonder if there exist a graphic display whit controller that embed the arabic alphabet and all the complex grammar rules.

Otherwise, I need to find a clever method to render the arabic alphabet on a graphic LCD. I must use 16 pixel high characters. There exist an internet resource where I can find the arabic alphabet already rendered? Maybe bitmaps.

thanks

I doubt and LCD has grammar rules in any language. A display is just displaying pixels and it up to the reader to see characters in whatever lettering. Grammar as rules above letters are way beyond the scope of displays.

On the character ones, I think I've only seen European+Katakana and European+Cyrillic as standard.

Many, many, years ago I had an almost identical requirement - moving from a couple of lines of text to an LCD capable of displaying Arabic. From memory your first challenge will be getting accurate translations!

We ended up scanning in the text we needed to display as tiff files, then writing a routine to display these on a graphics LCD (from an H8 as I remember). It was surprising just how high a resolution was required to get characters that were readable (to Arabic speakers, not me!). You will have to allocate a much larger area for the display, or have very little displayed at a time.

It is at least thinkable that in some other part of the globe, others exist. A mere matter of the market size. How many ten thousend per year can be sold. I admit not to know how many different alphabeths there are.

It might also be possible to define an adequate set of graphic elements that are cut directly into the glass, much like is already done. But it would take a serious graphics artist familiar with Arabic to decide if this could be done without using a high-res graphics LCD. With what little familiarity I have with Arabic, I suspect the task would be challenging, even then. Some of the accent marks need to be extended over pairs of characters and maybe even three or more.

I also seem to recall that numbers are rendered left to right, like English, but that the text renders right to left, otherwise. All this will make for some interesting word processing work.

You are allowed 8, but you can keep loading new ones. Changing one does not change the ones that are already displayed. It is a lot of work to update a display, but possible.
