| Post subject: | The Keyboard |
First of all, I would to apologise for my absence - I have been busy with other stuff (and still technically am). Anyway, down to business: How do I recieve keyboard input using C? Please remember that I am not using any standard includes (I have to code these myself). I followed the examples in bkerndev, but it wouldn't compile. From what I understand I need to setup the IDT, ISRs and IRQs before I can take input? Does anyone have any tutorials/help please? |

You need to first setup the GDT, then the IDT, and in those you will setup your ISRs and IRQs. After that, you are going to have to attach the keyboard to an IRQ. I don't exactly remember what the suggested is, but for now I have attached mine to IRQ1. If you want, I can work up a tutorial for the keyboard stuff for everyone and post it. It will take me a few days since I have other things, but it would probably be better than me just posting code here and you don't learn. <(o.o)> |

I have a GDT setup in ASM. A tutorial would be handy, Google is not being friendly. |

I think OSDev lacks IDT tutorials  So does everywhere, tbh.

Check out this tutorial. This will help you with the IDT, IRQ, and ISRs http://jamesmolloy.co.uk/tutorial_html/index.html This is what I used to help me start my kernel out in C and then I converted it to C++. Charles |
