external structur and L1823

ExternalStructu — Thu, 29 Oct 2020 09:50:37 GMT

Hi,

I do not understand the problem

I declare in header file

typedef union{  byte bRS_Event;  struct  {    byte bStatus_1:1;    byte bStatus_2:1;        }u;}ST_FLAGS_RS_EVENT;extern ST_FLAGS_RS_EVENT stRS_Event;

L1823: External object stRS_Event in C:\Prog\GRx\Project1.2\Project_Data\Standard\ObjectCode\trames_rs.c.o created by default

Help me

Thank you

Hello

The code snippet you have provided below is showing the declaration for variable stRS_Event.

Did you place a definition fro the same variable in one of your application .c file?

Definition should look as follows and must reside in a source file (not an include file).:

ST_FLAGS_RS_EVENT stRS_Event;
