eady state and then inserted into the ready list. Suppose I is a flag which reset automatically and the tasks (A, B, C) are listed in sequence in the waiting list. When I is ready, it will inform task A. Then I will be converted to the not-ready state. Therefore B and C will keep waiting for the next ready state of flag I in the waiting list. You can create a flag by calling CoCreateFlag() in <strong>CooCox</strong> <strong>CoOS</strong>. After being created, you can call CoWaitForSingleFlag() and CoWaitForMultipleFlags() to wait for a single flag or multiple flags. Code 4 Wait for a single flag void myTaskA(void* pdata) { .......... flagID = CoCreateFlag(0,0); CoWaitForSingleFlag(flagID,0); .......... } void myTaskB(void* pdata) { ...... CoSetFlag(flagID); ...... } // Reset manually, the original state is not-ready 36
Code5 Wait for multiple flags void myTaskA(void* pdata) { U32 flag; StatusType err; .......... flagID1 = CoCreateFlag(0,0); // Reset manually, the original state is not-ready flagID2 = CoCreateFlag(0,0); // Reset manually, the original state is not-ready flagID3 = CoCreateFlag(0,0); // Reset manually, the original state is not-ready flag = (1
