YetAnotherTeensyLaptop

Hi, Today I assembled both upper & lower Layouts of my Homemade Laptop (YATL)

Upper one uses a Teensy3.6 to drive CP/M Os, SDCard & SPI TFT Screen.

Lower one uses a Teensy 3.2 to read Keyboard & Joystick (not yet wired), drive MP3Player (& maybe later an ESP01 for WiFi).

I wrote a small TurboPascal3 Demo to show that even CP/M can interract with cool devices, display some pictures & play MP3s...

Hope my video be made soon...

Hi,

I started the support for more efficient text scrolling + colored console (w/ escaped chars)

Then added a 80 cols switchable mode (in addition than the 53 cols by default) .

Have a look ...

Hi, now some news about my YATL project (tiny homemade laptop),
after trying to fork bitlash script engine, then try to write a language interpreter by myself... I decided to start reusing an existing project : "RunCPM" a CP/M emulator ported to (BOOSTED) arduino like MCUs.

Few advantages with that solution : I can run already-written apps, and some scripting languages/environments such as BASIC & Turbo Pascal (Ahhh !).

Add to that experiment the capability of driving modern devices such as DFPlayer for MP3 playback, colored & graphical TFT screen, accessing the terminal by WiFi & telnet....
That sounds promising !

Hope it'll do something a day ...

Thanks for reading,
See soon.

Now : functions can handle Strings as arg. & return type. 

Strings can be constants, vars or a bulk memory area called "scratchpad".

Ex. Upper ( Split (dir (), 2) ) (simplified form) now works.

ADDED st("a$", "Hello World") & print rd("a$") user_functs to write & read StringVars

Hi, XtsBitlash (extended & typed version of billroy's bitlash) now works as well as original bitlash.

Soon may be able to manager String vars.

Yeah !

Hi, today my XtsBitlash (unofficial fork of billroy's bitlash) has succesfully compilled.

But @ this time functions are not working.

Hope it will soon.
