TMS570LC4357: RTI rtiResetCounter(rtiREG1, rtiCOUNTER_BLOCK0);

王工您好：

咨询个问题，我们使用rtiResetCounter清除rtiREG1->CNT[0].FRCx的值，但是根据打印，rtiREG1->CNT[0].FRCx的值时钟累加，并没有被清除，为什么啊？

难道rtiResetCounter这个函数不好用？

while(1)
{
rtiResetCounter(rtiREG1, rtiCOUNTER_BLOCK0);
uint32_t uc,fc;
fc=rtiREG1->CNT[0].FRCx;
uc=rtiREG1->CNT[0].UCx;
printf("CPUCx:%d %d %d %d\r\n",rtiREG1->CNT[0].CPUCx,uc,fc,value2);
}

Hi,

English:

We must stop the counter before reset.

So call the "rtiStopCounter" function before reset.

So use below code

rtiStopCounter(rtiREG1, rtiCOUNTER_BLOCK0);

rtiResetCounter(rtiREG1, rtiCOUNTER_BLOCK0);

uint32_t uc,fc;

fc=rtiREG1->CNT[0].FRCx;

uc=rtiREG1->CNT[0].UCx;

printf("CPUCx:%d %d %d %d\r\n",rtiREG1->CNT[0].CPUCx,uc,fc,value2);

中国人：

我们必须在重置之前停止计数器。所以在复位之前调用“rtiStopCounter”函数。所以使用下面的代码

rtiStopCounter(rtiREG1, rtiCOUNTER_BLOCK0);

rtiResetCounter(rtiREG1, rtiCOUNTER_BLOCK0);

uint32_t uc,fc;

fc=rtiREG1->CNT[0].FRCx;

uc=rtiREG1->CNT[0].UCx;

printf("CPUCx:%d %d %d %d\r\n",rtiREG1->CNT[0].CPUCx,uc,fc,value2);

Thanks & Regards,

Jagadish.
