simple delay function SC5xx

Hi Phil,

Unfortunately, we don't have any library or API for delay function. There is a function in ASM code for delay. Please find the attached project, in this project
the value of the variable "del_cycle" determines the delay cycles, you can modify the value of variable "del_cycle" based on your delay cycles requirement.

For more information about the ASM function used in this attached project, please refer the below CCES help path:
CrossCore® Embedded Studio 2.12.0 > SHARC® Development Tools Documentation > C/C++ Compiler Manual for SHARC® Processors > Compiler > C/C++ Run-Time Model and Environment > Function Call and Return > Mixed C/C++/Assembly Programming Examples > Using Void Functions.

Hope this helps.

Hey Santha,

Thank you, that is very helpful for me.

Hey Santha,

there is still a problem with the delay function.

If i call delay() in a c-file everything works, but in a c++ file there is an error at the linker level.
What do I have to change so that the function also works in a .cpp file?

Thanks again for your help.

Phil

Hi Phil,

To call the ASM function in C++ source file, you need to add 'extern "C" ' before the function declaration in CPP source file.

Please find the attached C++ project. Hope this helps.
