unknown type name „sfr“

Offline rugrat over 3 years ago

Hi,

I‘m a beginniner at embedded systems.

I added the „reg51“ header file (which I got from the Keil Website) to the source files for a project I am working on.

Having done that, I got the error message „unknown type name sfr“ which refers to the register definitions within the header file and I don’t know how to fix the issue.

I am using Keil 4.

Please help me....

Trouble is, whatever's on those CDs is likely to be written for tools and products decades out of date - so you're just going to keep hitting that same barrier!

:(

EDIT

Of the first 3 books on the http://www.keil.com/books page, one is dated 1998, and the other two are dated 2004. The Keil "µVision4 Getting Started Guide for 8051" is 2009.
