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!
Is There a Keil C lib help somewhere? 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
"Is There a Keil C lib help somewhere?" In uVision, just click on the name of a library function in your code - eg, printf - then press F1 and you'll get the help on that function. The same information is also in the printed manual, which is also installed in PDF electronic format & accessible via the 'Books' window. "Thirdly..." It's best to start a separate thread for unrelated questions! "But when I display the Value I get a funny weird value" How do you display it? What do you actually get? Have you used the debugger to examine what's actually stored in memory?
