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 |
