Does anyone knows a methode, to declare a const struct in code-space at a specific CODE address in C51? Background: I use a philips 87LPC767-MC and i want to store some code-revision-info in the 32Byte customer code space. I will define a C-Structure like typedef struct { unsigned char uc_software_code; unsigned char uc_main_version; unsigned char uc_sub_version; unsigned long ul_checksum; } CodeRefInfo_ts; CodeRefInfo_ts tsCodeRefInfo= { 0x04, 0x01, 0x01, 0x012345678 } at 0xFC0E; But it seems it is not possible to use the at-Keyword to locate a struct in the codespace?! Any suggestion? Thanks Markus
Hi Markus: This works for the C166. I use an assembly file and specify the start address with the CODE AT or ORG statements.
public CRC public ST_ADDR public ED_ADDR public PART_NUMB INFO_TAB SECTION CODE AT 0A000H INFO_PROC PROC CRC: dw 0432fH ST_ADDR: dw 00000H dw 04000H ED_ADDR: dw 00001H dw 0FFFFH org 0A010H PART_NUMB: db "123456-002-05", 0 INFO_PROC ENDP INFO_TAB ENDS END
