TODOs

  • TODO

    • TEXT console colorSet definition (done)

    • TEXT console colorSet changing routine (done) / made a fake monochrome LCD colorSet

      • make a BdosCall to change colorset ... (done)

    • TEXT conditional space char rendering (done)

    • TEXT smoother scrolling (line per line erasing)

    • lower layout (w/ addditional Teensy3.2 3.3v) (in progress)

    • REFACTO Screen API

    • REFACTO BdosCalls & VT-EXT (done)

    • GFX Pascal Demo (benchmark : loop for drawing rectangles as ex.) (in progress)

  • In Progress or Done

  • TTY emulation on TFT Screen (done)

    • tinyFont 3x5 => 4x6 => @320x240 => 80x40 chars

    • regular font 6x8 => 53x30 chars

    • ILI9341_t3n scrolling impl. is very slow for now

      • when no scrolling & screen overflow : seems to deadlock the teensy
      • have to make a console in RAM (80x30 gives 3200 bytes) [in progress & working]
      • use that cls/write abstraction to provide VT100 escape chars emulation ?
        • ^C // \b // \t // \r \n
        • cls
        • color
        • locate ? / bold ? (could be just diff color)
          • if text has attribs I'll have to store those
          • by spans / by chars :-( => on WSL & ubuntu that chars attrs seems to be ignored ....
          • as memseg is 1590 or 3200 -> I choosed to double it & make an attribMap
            • not the better idea but have enought RAM & faster solution

    • 1st, try a benchmark :

      • allocate memseg (1590 bytes for 53x30) [v]
      • fill all w/ a character [v]
      • display whole mem-console [v]
      • try to scroll [v]
      • see rendering time [nearly good]

    • then try bigger memseg that screen caps (DONE)

      • ex. 80x25 on 53x25
      • just for compatibility of softwares display

    • try to find the tinyFont for that lib (DONE)

  • Xtase handle inside CP/M code

    • find main loop

    • insert a call to one mine functions xts_hdl()

    • prevent from need of an Interrupt / Timer...

    • beware if cycles emulation ....

    • for System MENU (rather make CP/M pausing while UI)

    • Ext. Hardware functions ...

    • done once per operation (not cycle emulation)

  • Pascal (VT100Ex) extensions (see XTASE.PAS)

  • Z: Assets filename completion routine (done)

    • char* getAssetsFileEntry(char* assetName)

  • BMP Support :

    • before : Le croquis utilise 96188 octets (9%) de l'espace de stockage de programmes. Le maximum est de 1048576 octets. Les variables globales utilisent 85148 octets (32%) de mémoire dynamique, ce qui laisse 176996 octets pour les variables locales. Le maximum est de 262144 octets.

    • after : Le croquis utilise 97364 octets (9%) de l'espace de stockage de programmes. Le maximum est de 1048576 octets. Les variables globales utilisent 85148 octets (32%) de mémoire dynamique, ce qui laisse 176996 octets pour les variables locales. Le maximum est de 262144 octets.

    • done (minimal)

    • have to support smaller BMP w/ location (& no screen rotation)

  • BPP & PCT support

    • todo

  • Only one showImage() routine w/ file ext. detection (.BMP, .PCT, .BPP)

    • started in Bdoscall for drawing wallpapers

  • Console Mode Switcher (DONE)

    • 40 to 80 cols
    • (80 cols current font doesn't have lowerCase chars)
    • make a BDOS interrupt entry ... (maybe later)
    • or make a specific esc char sequence ( 0x7F 127 (seems that console is 7bits per default) )
      • can use $> ? chr$(127) with mBASIC

  • VTxx emulation

    • http://matthieu.benoit.free.fr/68hc11/vt100.htm

    • https://espterm.github.io/docs/vt100.codes.txt

    • not really as simple as that ...

    • B1 =====> try : will begin color

    • C1 =====> try : will end color****

    • 26 is CLS

    • WORKS :

      • TURBO (Pascal) works (even if could be better)
      • OS works

    • DOESN'T WORKS:

      • TURBO inside editor doesn't works very well (try Ctrl k + d to exit)
      • cause some different escapes

    • in Progress

      • TextEditor (nearly OK)

    • small BASIC script to handle VTxx

      • ? chr$(7) BELL
      • ? chr$(26) CLS
      • ? chr$(127) CONSOLE/MODE
      • ? chr$(27)+"B1"+"C"chr$(27)+"C1"+"oucou"

  • Keyboard support

    • Vtech Mobigo Keyboard

      • integrate it in XtsCPM (done)

      • done but too slow

      • may be do the poll on TimerInterrupt ???? (tried... : to improve...)

        • better times but buzzer ~blinks

    • Microsoft XBOX 360 Chatpad (now works - french layout)

      • stdIO handling (Serial IN / Chatpad IN -- Serial OUT / TFT OUT)

        • BOTH are treated w/ same priority for now

      • Spe keys

        • will need to have a CTRL like key (ex. for TE)

        • greenSquare & redCircle are all used to make speChars

        • no ESC key // a bckSp key

        • have a -peopleKey- that could emulate CTRL Key

        • may -peopleKey- + [<-] could do ESC

        • then -peopleKey- + [->] could do another spe key

          • maybe YATL specific hdl :

          • [MENU]

            > TOGGLE CONSOLE MODE

            > SELF TEST

            > REBOOT

  • cpm.h l. 736

  • free Bdos hooks (225-229 inclusive are free)

  • Z machine for CPM

  • Pascal & realted resources

  • Buzzer support

    • 7 make bell tone

  • to " play 'a#bbca' " could use a tty escSeq ?

    • T5K uses the following format => 5KB / 3 => ~1700 notes (have headers)

  • T53 uses =>

    • to play "MARIO.T53" could have something like : ? chr$(27)+ "$" + "MARIO.T53" +"!" ? chr$(27)+ "$" + "MONKEY.T5K" +"!" ? chr$(27)+ "$" + "A#BBCD" +"!" (done)

    • limited this system to 64 bytes !

    • by default : it will lock the system while playing

    • later : make a Threaded version (/!\ with delay(..) & Timers )

  • LED support

  • Usefull commands

  • PIP B:ED.COM=A:ED.COM Copy the disk file "ED.COM" from disk "A" to the file "ED.COM" on disk "B". The source file and the destination file will use the current user area code. A shorter form of the command could be used because the destination file name is the same as the source file name.

  • PIP B:=A:ED.COM A short version of the previous example.
