Hi dryPants...

Do you have some other good advices for me?

Yes. Python is a very strict language and has libraries for just about anything that anyone in the coding industry is likely to encounter.

Before deciding to hammer any hardware, (and yes I have done much in this area), experiment coding for something less likely to cause you serious headaches.

Once you feel confident try experimenting with an Arduino, USB type, as an example.

In *NIX flavours it is easy to R/W from/to even with shell scripting. I have uploaded much code to do this mainly in Python for multi-platform use, (including a serial port stock AMIGA A1200 with HW mods to the USB Arduino), I love "banging the metal"...

I personally love assembly but........
......don't expect to get to Ring 0 directly in current OSes you WILL have serious headaches finding that you can't. The days of MS-DOS where BIOS and other assembly access and calls are long gone.

Study things like ISA, PCI bus design and limitations as examples then progress to current technology. I studied the PCI slot for months only to realise my limitations at home built hardware was way beyond any beginners scope.

Hope this helps...
