协议栈按键轮询方式如何使用，中断方式ok，轮询不通

协议栈按键轮询方式如何使用，中断方式ok，轮询不通

外部按键在P06

修改如下

#define HAL_KEY_SW_6_PORT     P0
#define HAL_KEY_SW_6_BIT    BV(6) //BV(1)
#define HAL_KEY_SW_6_SEL    P0SEL
#define HAL_KEY_SW_6_DIR    P0DIR

/* edge interrupt */
#define HAL_KEY_SW_6_EDGEBIT BV(0)
#define HAL_KEY_SW_6_EDGE HAL_KEY_FALLING_EDGE

#define HAL_KEY_SW_6_IEN     IEN1 /* CPU interrupt mask register */
#define HAL_KEY_SW_6_IENBIT     BV(5) /* Mask bit for all of Port_0 */
#define HAL_KEY_SW_6_ICTL      P0IEN /* Port Interrupt Control register */
#define HAL_KEY_SW_6_ICTLBIT     BV(6)//BV(1) /* P0IEN - P0.1 enable/disable bit */
#define HAL_KEY_SW_6_PXIFG     P0IFG

#define PUSH1_BV      BV(6)//BV(1)
#define PUSH1_SBIT    P0_6//P0_1

其他未修改，但是按下按键无法进入中断，

设置断点，系统可以进入轮询函数void HalKeyPoll (void)中

但是 在执行下列语句时，会直接return，将return注释掉，ok了，就变成了检测高电平

if (!Hal_KeyIntEnable)
{
if (keys == halKeySavedKeys)
{
/* Exit - since no keys have changed */
return;
}
/* Store the current keys for comparation next time */
halKeySavedKeys = keys;
}

Do you define

ISR_KEYINTERRUPT ?

I  want to use key poll method instead of key interrupt, so i think i do not need to define ISR_KEYINTERRUT  AM I RIGHT?

zstack default is key polling, so just change your key pin define.

you may set a breakpoint in HalKeyPoll() to watch.

yes  i have changed pins and i set breakpoints  in HalKeyPoll() 

but it would jump  HalKeyPoll() ,and when i comment  sentence return， code is ok

if (!Hal_KeyIntEnable)
{
if (keys == halKeySavedKeys)
{
/* Exit - since no keys have changed */
return;
}
/* Store the current keys for comparation next time */
halKeySavedKeys = keys;
}

这个return进入是正常的，只有当按键按下的时候，不会进入了。

P0.6原先协议栈中，用作joystick的输入了，会不会这个影响了。
