Hi John,
I have checked up my own ".dyn" file in sigma studio,and it does work as the default ".dyn",except for more code space required.For the default ".dyn" file,only 1224 bytes are needed after assemble to sigma studio ".dll" and applied as a delay module,by contrast,1948 bytes of code space are needed for my own ".dyn".
Thanking you for your detailed answer and assistance,I understand the procedure to create custom module quite a few.Thanks.
Best Regards,
Liang
