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

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

Hello Mikael, hello FF friends,
I'm sorry, the code runs fine but it doesn't work even with the latest
Flashforth customizations! I have been working on the implementation of
Optiforthbasics for a week --> without success. But with my 73 1/2 years
this is too long for me --> unfortunately I am a “C/C++ programmer” and
not a “Forthler”.

Stefan has probably done a great job with his Optiforth. Porting a
project in C/C++ to any processor is not science --> always works! Why
this seems so difficult here -> even in the same Forth dialect <- is
unclear to me, but does it explain that there are so few graphics
samples or that real Forth users are satisfied with an output on their PC?

I have hobbyistically “married” many displays with various MCU families,
Renesas, Intel, STM32F0...4, rp2040 up to the Arduinos (except ESP'S)
--> for me a project without visual output is like a soup without salt! 
In my home projects, I draw all graphics (from computer ... piano, HMI
... instrument) via mouse, usually scaled to size & pixel-accurate and
automatically create the Arduino code (including tasks).  Inspired by
“Forth”, I have now adopted “direct communication” so that I can work
“directly” as in Optiforth.

I have compensated for the many system crashes with “direct flashing
from the terminal” but the installation of single-step operation has not
helped much. Only “Dot & Rect” still work as in the first program
“TFT-Shield_0.txt” v. 21.08.2024!

Finally, I created 3 small demo programs for Mikael's Flashforth to whet
your appetite for Flashforth graphics:
Intro-FF.txt: improved display of the FF intro
Schachbrett.txt: small graphics can only be created with Dot & Rect's
Wasserregelung.txt: a small HMI picture (“HMI.jpg” dto. in
Optiforthgrafik, with Line/Circle/Ellipse/Roundeck --> small improvements).
Greetings
Peter
PS: So if someone is interested in Forthgrafik outputs and can implement
the program TFT_FF_3_RE_Lin.txt from 28.08.2024, it goes on.
Tip: TFT-Shield's are available e.g. at “www.az-delivery.de” --> “Shield
2,4 TFT” for 13,99 € and “www.reichelt.de” --> “ARD SHD 2,4TD” for 8,50
€ or also https://www.elecbee.com/ --> $8,99
