TI中文支持网我现在通过按键可以从CC2541板子往蓝牙模块发数据了，但是老板要求按下按键灯亮，松开按键灯灭。
if ( keys & HAL_KEY_SW_1 ) //UP 开始键
{
attWriteReq_t req;
BLE_DEV *p = &(gDev[simpleBLEScanIdx]);
req.handle = GUA_CHAR1_Hdl; //simpleBLECharHdl;
req.len = 3;
req.value[0] = 0x31;
req.value[1] = 0x0D;
req.value[2] = 0x0A;
req.sig = 0;
req.cmd = 0;
//simpleBLEConnHandle=0x0000;
p->simpleBLEConnHandle=0x0000;
simpleBLETaskId=0x0B;
status = GATT_WriteCharValue( p->simpleBLEConnHandle, &req, simpleBLETaskId );
HAL_TURN_OFF_LED1();
}
HAL_TURN_OFF_LED1();这个是灯亮，和官方板子接的方向不一致。
这个按键处理
// 按键处理
static void simpleBLECentral_HandleKeys( uint8 shift, uint16 keys )
在这个函数里面。
按键使用下降沿中断搞的。
现在按下键可以灯亮。
至于松开灯灭，我想这样实现。
再搞一个上升沿检测，检测到上升沿让灯灭。
还得搞一个函数，在函数里判断。
总觉得SDK里的很复杂，不知道具体怎么操作，谢谢！
ccb bcc：
我写一下操作步骤：
先定义宏定义
#define HAL_KEY_SW_1_EDGE1HAL_KEY_RISING_EDGE//上升沿

那你應該是去改HAL_TURN_OFF_LED1跟HAL_TURN_ON_LED1吧
ccb bcc：
回复 YiKai Chen:
不是啊。我现在按下可以灯亮了。
SDK里没有检测上升沿，所以没法灯灭。

调用定义的那个函数：
if ( keys & HAL_KEY_SW_1 ) //UP 开始键 { attWriteReq_t req; BLE_DEV *p = &(gDev[simpleBLEScanIdx]); req.handle = GUA_CHAR1_Hdl; //simpleBLECharHdl; req.len = 3; req.value[0] = 0x31; req.value[1] = 0x0D; req.value[2] = 0x0A; req.sig = 0; req.cmd = 0; //simpleBLEConnHandle=0x0000; p->simpleBLEConnHandle=0x0000; simpleBLETaskId=0x0B; status = GATT_WriteCharValue( p->simpleBLEConnHandle, &req, simpleBLETaskId ); HAL_TURN_OFF_LED1(); HalKeyConfig1( HAL_KEY_INTERRUPT_ENABLE, OnBoard_KeyCallback); //灯亮马上重新配置上升沿中断 }
ccb bcc：
回复 ccb bcc:
uint16 HalKeyRead ( void )
void HalKeyPoll (void)
这个两个函数我不打算改了，感觉不用改。
那么在哪个中断函数里判断上升沿或者下降沿呢？谢谢
void halProcessKeyInterrupt (void)
HAL_ISR_FUNCTION( halKeyPort0Isr, P0INT_VECTOR )
HAL_ISR_FUNCTION( halKeyPort1Isr, P1INT_VECTOR )
ccb bcc：
回复 YiKai Chen:
谢谢！我弄好了。开始侦测下降沿，判断按键按下；
侦测到下降沿马上配置侦测上升沿，判断按键抬起。
如此循环。
