Hi everyone
My project is to developpe another way of displaying characters on screen.
I'm inspired by what you can see on some pinballs (for example), you know, thoses segments forming numbers and letters !



At the moment, I just wrote the main routine which consists of decoding a 16bit value (corresponding to the 16 segments composing the character) stored in a list (for now, only the numbers+alphabet...more later, among 256 elements) then it displays the result.
It 's possible to change individually the colors of each character (background, color of segment when off, color of segment when on)
First I had chosen the 8bit-per-pixel mode (256 colors)
Today I've decided to convert my program to standard direct mode (16bpp, 65535 colors coded 5-6-5 bits)
Now it's easier to select colors and I can make screenshots (I'm a linux user, and I failed to install CEmu...Luckily TILP2 is here ! )

Here are screenshots :




Width goes up to 12 characters , and height up to 6.

I'm gonna post the code as soon as I have put comments in it...Please be patient

I think I'm gonna take a true standard extended ASCII table as reference
(just have to put a sentence between ' when using SPASM)

Don't hesitate to put your suggestions

That is quite cool, i was considering to do something similar for my clock add-in on casio prizm initially but because casio also do watches etc I decided to keep the style as close as possible to their 8 segment digits style (sometimes it is not exactly same segmentation once week days' etc letters get introduced like on some casio g-shocks). It was quite hard to have the slightly tilting lines show as smooth lines and would not have worked if i used just two colours - so for now I dropped the idea of optional colour settings and only do it in one casio like style - you can see the sprites and screenshots if you wish by following the g-clock link in my signature.

I noticed you opted to straighten the letters to be completely vertical but they look very good, and those segments slightly visible in off state are very nice touch as well. Have you considered creating a digital clock display out of your characters if you can redraw them fast enough for that. For my casio add-in I tried to optimize the refresh to only do segments which needed changing to avoid delays if it is something needed by you.

Congrats on your progress with this project.

Is there a reason why you switched from the faster 8bpp to 16bpp? That seems like a rather interesting decision to me Anywho, this looks pretty neat indeed; glad to see people are doing assembly programming for the CE!

Thank you for your encouraging comments !
Amazonka, I took a glance at your work G-Clock...Very nice job !
I did not tried the italic version because I thought the result might not be as neat (maybe an improvement , later... )
Mateo, I switched from faster 8bpp to 16bpp because I was fed up with ugly screen when back to TI-os and most of all because I just don't know how to define colors correctly when in 8bpp mode :I had initialize palette mem, then I was lost in colors...Just did not know how to select one but randomly-blind
Is it possible to select a color in this mode with RGB in mind ?
(anyway I keep the 8bpp version in a corner, in case of...)

(I'm typing binary codes of characters ...)

You have to A. restore to 16bpp mode when returning to TI-OS. and B. Use 1555 color (or setup the palette and use xLIB colors), all this is right here: Mateo's CE documentation.
Use RunerBot to convert from rgb to 1555 color, by the way

Cool, I go over there to read it, thank you, KingInfinity

EDIT: I forgot to post the code ! Here it is :

Oh by the way, I switched back to 8bpp mode


Code:

If you get a chance, you should upload the binary and source with a README in a zip to the Cemetech Archives! Great work on this; it looks very accurate to the original.

Good news !
I updated my program (now simply named SEGMENTS) in order to get it available from Basic, thanks to ANS !
(Yes, I went back to 16bpp mode)
I searched for variables we rarely use in Basic.
So, I chose the variables O (for cOlumn) and L (for Line) dedicated to define the output coordinates
(With O from 0 to 11 , and L from 0 to 5)
I also chose the variable Theta for the color value from 0 (=black) to 7 (this also set minuscule letters mode ON : you know, when double pressing [alpha]!)
NB: this value is a modulo 8 : to leave minuscule letters mode , just put the same color value +8

There is also a "Disp mode" you can activate by simply putting value >11 in O

If you want to clear the screen (all black) , just put an empty string in Ans

Here's an example to see what it looks like:
