unknown type name „sfr“

rugrat over 6 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....
