I got information that ATI uses special I2C

Yeah, and now?

Btw: you see, that this code (as many parts posted by you before) is under the GPL. So I hope you will publish your sources...

[Razor]

I will post it becouse i want other to know as well and learn becouse this isnt the usual topic and it is in the opensource topic.If you help it will be published soon if you need any info i can ask rivatuner or atitool author.

Hilfe!! :oops:

[Muetze1]

If you help ...

No, I won't help. So I need no help and so I need no informations. DIY! I had learn many things many years before - so you can do it the same way. Learn and try and you will achieve success.

[Razor]

You disapointed me Muetze how can you write code for other users how!I mean please...but ok i understand...I am not german thats why... :x


If someone knows C++ please translate this becouse if DP wants support for ATI translate it..i cant

[Muetze1]

Zitat von Razor

how can you write code for other users how!

Because other users show that they are dealing with the topic and are trying to learn something new. They wanted to learn and also do this. You got something done (e.g. the CPU temp on intel), but you have not yet followed e.g. one hint: learn the basics! You still ask questions about basic things, even about retrieving the results of a function. You that you are not willing to learn the language but you still bother to get your code together. You use any thread to get this and you post so many messages you need, till you get it nearly finished. But you even fail in glueing the sources together...

I am not willing to build your application and I am not willing to help you, as long as you only spam to get your result, directly fitting in your sources. You have not basic skills but want the highest achievements. I respect your endurance - really!

Zitat von Razor

but ok i understand...I am not german thats why... :x

You know that's not the reason and instead of being encouraged to get the solution and try to learn the needed things, you try to still get from other people (me or even other)...

Zitat:

Zitat von Razor

i cant

You can, but the worse thing: you need to do it by yourself and you even have to learn something for that, etc.

But why you always get back here? Nobody else found in the english-speaking/writing boards/sites?

It is really pathetic, what you try to do here...

[Razor]

If i can learn i need an example this is my way of learning but i dont know about yours...its just weird that u write code or translate for other for me u wont.But i want to learn aswell. :?


Or you dont know how to or you are just making a fool of yourself. :P

[OlafSt]

You still didn't got the point, razor.

For example, pick this ATI-Problem. You are posting code which is written in C (not C++, but that is not important here). It is also some code for linux-machines. Of course this is simply impossible to port 1:1 to a windows-machine as linux and windows differ extremely in talking to hardware. Three or four times we mentioned this fact - still you're posting linux-code.

What @Muetze1 and myself and all the others here want from you: You already figured out that ATI uses the I2C-mechanism to publish the data we want to see. So why the hell don't you move your ass and learn HOW TO ACCESS I2C on a windows machine ? This is what @muetze1 and we all here name "basics".

There you (and finally we all) will learn a lot more from.

[Larsi]

Ich hab ne Geforce FX 5200; die hat keinen Temperatursensor, oder???

[Razor]

An example! :)


So if i am here to learn then YOU post a code since we all want to read ATI! :cry:
