uC/OS-II Help Needed

Dear Engineers.

I am working on a project written before using ecos, now I want to run it on NIOS II and I converted the code but I face a problem now, how can we create and deal with Flags.

for example

cyg_flag_t X_flag; /// For Creating a flag in eCOS

cyg_flag_value_t to_Y;

to_Y = cyg_flag_wait( &X_flag,

0xFFF,

CYG_FLAG_WAITMODE_OR

| CYG_FLAG_WAITMODE_CLR);

if (to_Y = 1)

cyg_flag_setbits (&X_flag, to_Y);

The above code is a part of ecos, we can create a flag with it, do some pending, and then setting some valuse.

If anyone can help me to convert this code to uC/OS-II

    I believe you are looking for the "OSEvent" API's. See Section 2.21 and Chapter 9 of the UCOS-II book.

    Yes I saw this, but from eCOS we have just flag and flag value to use for set and wait services, while in uCOS we have flag group, os_flag, node,etc thats why I am confused
