Read-Only Author Phil Ouellette Posted 27-Nov-2001 02:46 GMT Toolset C51	Sharing #defines and EQU statements Phil Ouellette Does anyone know if there is a way to make a #define in 'C' visible to A51 code (or visa-versa)? I know how to make a header file in Hi-Tech C51 that will let 'C' and 'A51 definitions coexist, but can't figure out how to this with Keil. In Hi-Tech's C51 compiler you can create a common ('C' and 'A51') header file like this: ; #define C_1 1 ; #define C_2 2 ; #define C_3 3 ;#if (0) ASSEM_1 EQU 1 ASSEM_2 EQU 2 ASSEM_3 EQU 3 ;#endif But when I try this in Keil it chokes on the ; before the #define. Any ideas?

Read-Only Author Support Intl Keil Posted 27-Nov-2001 07:38 GMT Toolset C51	RE: Sharing #defines and EQU statements Support Intl Keil A51 Version 6 adds a C preprocessor to the assembler. Therefore it is possible to use #define statements also in the assembler language. If you have an older version of our tools you should consider to upgrade it.

You can define different targets for example one with watchdog and an other without watchdog. ...Leo

The C preprocessor in A51 will process those lines.
