TI中文支持网Hi,
I want to add a Task that interval every 100 ms operate 1'st. My code are as follows:
#include <string.h>

ctttaskParams.stack = cttTaskStack;
ctttaskParams.stackSize = CTTTASK_STACK_SIZE;
ctttaskParams.priority = CTTTASK_PRIORITY;
Task_construct(&cttTaskStruct, CTTTask_Fxn, &ctttaskParams, NULL);
}
void CTTTask_Fxn(UArg a0, UArg a1)
{
Don_test1 = 0;
Don_test2 = 1;
CTT_init();
for(;;)
{
uint32_t events;
// Wait for an event to be posted
events = Event_pend(syncEvent, Event_Id_NONE, CTT_ALL_EVENTS,
ICALL_TIMEOUT_FOREVER);
Don_test3 = events;
if(events)
{
// ICall_EntityID dest;
// ICall_ServiceEnum src;
// ICall_HciExtEvt *pMsg = NULL;
Don_test1++;
Don_test2 = Don_test2 + Don_test1;
}
}
}
static void CTT_init(void)
{
ICall_registerApp(&selfEntity, &syncEvent);
Util_constructClock(&periodicClock, CTTTask_clockHandler,
CTT_PERIODIC_EVT_PERIOD, 0, false, CTT_PERIODIC_EVT);
}
static void CTTTask_clockHandler(UArg a11)
{
// Wake up the application.
Event_post(syncEvent, a11);
}
My questions are as follows:
1, My code jest run CTTTask_Fxn(UArg a0, UArg a1) program 1'st, not interval every 100 ms operate 1'st.
2, How to modify my program, let it interval every 100 ms operate 1'st.
Any idea how can I solve the problem? Every help would be really appreciated!
Thanks in advance.

可以考虑使用硬件定时器中断。
Susan Yang：
您需要使用Util_startClock
void Util_startClock ( Clock_Struct *pClock )Start a clock.Parameters pClock - pointer to clock struct
Liu Don：
回复 da qin zheng sheng:
使用硬件定時中斷是個不錯的建議，請問有建議的範例程式可以參考的嗎??
在cc2640R2F程式中，硬體中斷似乎是最高優先權，程式運作過程中會影響原先在Task中運作的藍芽程式嗎??
Liu Don：
回复 Susan Yang:
我有增加"Util_startClock(&periodicClock)"指令於我的"CTT_init(void)"副程式中，但似乎沒有效果，程式一樣只執行我的CTTTask_Fxn(UArg a0, UArg a1)副程式一次而以，並沒有辦法每隔100ms執行我的CTTTask_Fxn(UArg a0, UArg a1)副程式。
目前程式如下：
請問我還有哪個地方欠缺考慮的嗎??

Util_startClock只是one-shot clock，需要反复调用startClock，如果需要实现interval operation
