Does anybody know, if it is possible in lazarus to keep your command
line window open and writeln to it.

At the same time i need to create a form by code, and see
visualizations draw on a TImage on the form

At the same time

I am compiling in the command line in Lazarus 2.0.10 FPC 3.2.0 on a
Raspberry ZERO

Anybody got URL or example code ?

Attached a photo of my project so far ! Great Thanks!

Yeah, just start your application from your terminal window. Try it
for example with lazarus itself and it will output some debug
messages.

btw:

That is really stretching it. If you need to rebuild lazarus itself
you will run out of memory (requires > 1024 MB almost 2048 MB these
days) and yes you can swap but that will be slow as f*ck.

Use Controls/Forms Canvas and draw however you like.

raylib+reygui?

Another option would be the framebuffer from console (e.g., the way
mplayer works using fbdev2 ), but I don't know what is the freepascal
support for that...
