Re: [Flashforth-devel] building flashforth with avra?

[Frans-Pieter V. <ner...@xs...>]

Hi Peter,

modelling gasflow is way beyond my knowledge, but is fascinating science. I can imagine that the enigneers of the Concorde still had small slide-rules in their pocket. 
I have touched upon some modelling waterflow with discretized Saint Vennant equations in the late nineties, early 2000ths. The core of the model was written in FORTRAN. At the company I worked we used Slackware Linux to use compile the code and the software ran on single core Pentiums. No parallel computations.   
Speaking of FORTRAN and Forth.
The late Julian Noble had written a book about it:
https://github.com/Josefg/Scientific_FORTH
He uses FORTRAN syntax to write numerical equations.

And there is a sort of "Numerical Recipes in Forth" website:
https://www.taygeta.com/fsl/scilib.html

I can imagine that lineair regression analysis on sensor data in FlashForth could be usefull.
Which probably brings me back to for the manuals for engineers for hp calculators. Which the spaceshuttle engineers had in their pockets.

Greets,
Frans-Pieter

I found out that gitlab and github support this format. With your cheatsheet I tried to seperate the Atmega from the PIC information. Did not succeed yet. Probably that TEX is still the best solution for compact cheatsheets.

The arduino IDE is what we use normally, as the examples and code are self-explanatory and easy to copy and paste. However, when I master FORTH enough I will introduce them to ForthForh. Learning to program in FORTH alongside an introduction about the inner workings of the microcontroller can form an interesting course.

This physical "evidence" that memory is not just an abstract concept but really exist inside the microcontroller is a strong didactic argument. Likewise in biology, when you teach about cells students prepare samples and study them under a microscope. And in advanced classes you even experiment with dna, the program off life.

Grinding the protective layer with find sandpaper and heating and breaking of the protective shell should be possible. So using the biological analogy, with FORTH you can reprogram artificial life.
