请教各路大神！cc2640进去shutdown模式后，分别两个按键唤醒。唤醒后怎么知道是那个按键触发的？
rt！
参考board_key.c 的回调函数Board_keyCallback

非常感谢
在SimpleBLEPeripheral按照上面的代码修改了程序，发现在rtos中进入shutdown模式按键唤醒后，没有回调TY

static void Board_keyCallback(PIN_Handle hPin, PIN_Id pinId)函数，参考了BloodPressure的demo修改，还是没有回调！我猜应该是不是进入shutdown模式之后命令已经不执行了！最后参考了CC26xx/CC13xx Power Management Software Developer's Reference Guide第15页
When wakingup froma shutdown,the device reboots.The inputand output state is retained through shutdownto avoid glitches.Software usingthe shutdown-power mode calls SysCtrlResetSourceGet()early in the application to check the wake-up source.If the device wakes up from a shutdown,the application restores the configuration of the input and output registers before opening to latches to avoid glitches.Write AON_SYSCTL:SLEEPCTL[0]to 1 to unlatchthe inputsand outputs.
在SimpleBLEPeripheral_init(void)调用下面代码即可判断
/* Get the reason for reset */
uint32_t rSrc = SysCtrlResetSourceGet();
isWakeupPin = 0;
/* Do pin init before starting BIOS */
/* If coming from shutdown, use special gpio table.*/
if(rSrc == RSTSRC_WAKEUP_FROM_SHUTDOWN)
{
if ( PIN_getInputValue(IOID_12) == 0 )
{
isWakeupPin = 1;
}
if ( PIN_getInputValue(IOID_14) == 0 )
{
isWakeupPin = 2;
}
}
