mixing C with AS - example needed

["Grzegorz !Kubik" <g.kubik@xxxxxxxxxxxx>]

Hello,

I am trying to combine part of software written in C with another part 
written in AS.
Example is needed, how to:
- call assembler procedure from C program,
- define and use RAM buffer common for C and assembler programs.

I am using WinAVR, my target controller is AT90USB1287.

Thank you for any help,
Regards,
Greg Kubik
