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Trouble is, whatever's on those CDs is likely to be written for tools and products decades out of date - so you're just going to keep hitting that same barrier!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