关于CC2640R2F pinshutdown 问题

您好，我在运行例程pinshutdown中，发现是 Power_shutdown(0, 0);查阅资料发现有两个参数可以更改，

int_fast16_t Power_shutdown(uint_fast16_t shutdownState,
uint_fast32_t shutdownTime)；

请问shutdownTime这个参数，cc2640R2F支持吗？谢谢

我当时在例程添加了点灯，测试了这个，发现好像是不支持的：

#define SHUTDOWN_TIME 100000

…..

Power_shutdown(0, SHUTDOWN_TIME );

PIN_setOutputValue(hPins, Board_PIN_LED0, 1);  //没有亮灯

看下这里的说明

谢谢回答，我测试下来，在设置时间内并没有自动执行周期时间，应该是不支持吧

是这样设置的
static void taskFxn(UArg a0, UArg a1)
{uint32_t sleepUs = 500000;Task_sleep(sleepUs / Clock_tickPeriod);PIN_setOutputValue(hPins, Board_PIN_LED1, 1);Task_sleep(sleepUs / Clock_tickPeriod);PIN_setOutputValue(hPins, Board_PIN_LED1, 0);Task_sleep(sleepUs / Clock_tickPeriod);PIN_setOutputValue(hPins, Board_PIN_LED1, 1);/* Turn off LED0 关闭LED0*/PIN_setOutputValue(hPins, Board_PIN_LED0, 0);
/* Go to shutdown 关机*/Power_shutdown(0, SHOUTDOWN_TIME);
/* Should never get here, since shutdown will reset. */while (1);
}
