Ibutton dallas

I am very very very very new to the c enviroment of keil ,yet I want to know a bit more ,Is There a Keil C lib help somewhere?

Second ly I have tried to write to my intelligent lcd threw the Keil compiler , it works threw my address lines of the mcs51
,is their a library or code examples somewhere of how to write data to the lcd ?
I have tried example code but it doesn't initialize my Lcd even!


Thirdly I am currently writing most of my applications in asm51 (takes time) , and are struggelling with reading data from The Dalas Ibutton 1992 ,using the 1 wire protocal,my write_one,write_zero ,and initilize procedure's works as tested on osciloscope!
I send it a 33h to get Id of button!
My read work according to timing loops as tested with osciloscope,
But when I display the Value I get a funny weird value back and not the 64 unique id I want!

    In uVision, click on the "Books" tab of the box in the upper right hand corner. Under "Tool User's Guides" you should see "C51 Library Functions".

    This tab corresponds to a help file in the directory for such, probably

    C:\Keil\C51\HLP\C51lib.chm
