[Flashforth-devel] Flashfort and UNO-TFT display/ili9341

[Peter H. <p.h...@we...>]

Hello Mikael, hello FF friends,
I might need your help again.
After 2023-04-08 I was helped by Stefan regarding my request for the TFT
display/ili9341 -> https://github.com/bitflipser helped me.
He has programmed TFT “basic routines” and I some “Forth terminals”,
“controls” and “extensions”.
With his Optiforth we were both able to realize Forthgraphic routines
via PC, e.g. drawings/piano/chessboard/HDMI images etc. in just a few
minutes.
Everything is selected/positioned/drawn using the PC mouse and the code
is automatically sent to the UNO and displayed pixel-accurately.
Problems -> Optiforth is only available for the UNO_328P/32kB and Stefan
is unfortunately out. With larger processors there would be further
advantages here.

After having tested all Forths known to me before and having tested
Mexrips, noForth & ZeptoForth afterwards,
I think Mikael's Flashfort is clearly better, again --> congratulations!
What could perhaps be a little more would be more hardware resources.
That's why I had handed over the sources for “LCD-Shield on UNO-Board”
in March 2023 and also programmed a control control for it in the last
two terminals.

Attached is now a small basic program for initializing the “TFT-Shield
on UNO-Board”. Simply use the familiar -> 2.4 inch TFT LCD Touch Display
Shield for 5V <- the UNO. It implements the -> “FF” (Flashfort) display
on the TFT display as an example in the color frame.
I can't offer more at the moment, because in Flashforth there are the
commands:
*_0until, 0if, do, loop and pick_* unfortunately not!

Who can help me? If I could use these words, the previous solutions
(with PC mouse via lines/dots/circles/round
corners/rectangles/buttons/graphics)
would be easily possible in real time. I would be happy to make final
programs and terminals including controls available to the FF community.

best regards
Peter

_Note on program transfer times:_  --> with Teraterm (TD >= 250ms/line!)
the time at 38600 Bd is approx. 9 sec. I generally work with 115200 Bd
in FF and achieve 2 sec. in my Windows terminal or if I switch
internally to my DOS terminal --> 1 sec.!!!).  This instruction
(https://wellys.com/posts/flashforth_compile/) works well with the
250000 Bd (--> e.g. in my terminal the Win times/DOS times are halved
again!). If you don't want to install the huge MPLAB X IDE v.6.20 you
can simply change the baudrate in the hexfile:   original: 00004D93 33
(38600 Bd)    --> 30 (115200 Bd)    --> 37 (250000 Bd)_
