Hi Salam,

there are many different ways:

1.
you declare the variables as public in assembler and extern in C

2.
vice versa.

3.
you store the variables at a fixed address and define variables at fixed adresses in C with the _at_ statement.

4.
You give a pointer to the assembler program, at which it must store the data.

5.
the assembler routine return pointer with the address, at which the values are stored.
