从Zigbee协议栈底层添加自己的按键配置

本实验是基于ZStack-CC2530-2.5.1a版本的协议栈来进行实验的，整个实验需要改动hal_board_cfg.h、hal_board_cfg.h、hal_key.c、hal_key.h和自己定义的Coordinator.c这5个文件。

注意：添加自己的按键时尽量不要修改协议栈里面的按键程序，自己另行添加即可。

1、hal_key.h在/* Switches (keys) */下面添加自己的按键定义#define HAL_KEY_SW_8 0x80图1：----------------------------------------------------------------------------------------2、hal_board_cfg.h在/* S6 */#define PUSH1_BV BV(1)#define PUSH1_SBIT P0_1#if defined (HAL_BOARD_CC2530EB_REV17)#define PUSH1_POLARITY ACTIVE_LOW#elif defined (HAL_BOARD_CC2530EB_REV13)#define PUSH1_POLARITY ACTIVE_LOW#else#error Unknown Board Indentifier#endif下面模仿/* S6 */下的程序定义自己的按键值：/* S8 */#define PUSH8_BV BV(4)//修改#define PUSH8_SBIT P0_4//修改#if defined (HAL_BOARD_CC2530EB_REV17)#define PUSH8_POLARITY ACTIVE_HIGH#elif defined (HAL_BOARD_CC2530EB_REV13)#define PUSH8_POLARITY ACTIVE_LOW#else#error Unknown Board Indentifier#endif图2：------------------------------------------------------------------------------------------------------------- 在/* ----------- Push Buttons ---------- */#define HAL_PUSH_BUTTON1() (PUSH1_POLARITY (PUSH1_SBIT))#define HAL_PUSH_BUTTON2() (PUSH2_POLARITY (PUSH2_SBIT))#define HAL_PUSH_BUTTON3() (0)#define HAL_PUSH_BUTTON4() (0)#define HAL_PUSH_BUTTON5() (0)#define HAL_PUSH_BUTTON6() (0)下定义自己的按键函数#define HAL_PUSH_BUTTON8() (PUSH8_POLARITY (PUSH8_SBIT))图3：---------------------------------------------------------------------------------------------------------------- hal_key.c在/* SW_6 is at P0.1 */#define HAL_KEY_SW_6_PORT P0#define HAL_KEY_SW_6_BIT 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/* SW_6 interrupts */#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(1) /* P0IEN - P0.1 enable/disable bit */#define HAL_KEY_SW_6_PXIFG P0IFG /* Interrupt flag at source */下模仿/* SW_6 is at P0.1 */建立自己的按键函数#define HAL_KEY_SW_8_PORT P0#define HAL_KEY_SW_8_BIT BV(4) //修改#define HAL_KEY_SW_8_SEL P0SEL#define HAL_KEY_SW_8_DIR P0DIR/* edge interrupt */#define HAL_KEY_SW_8_EDGEBIT BV(0)#define HAL_KEY_SW_8_EDGE HAL_KEY_FALLING_EDGE/* SW_8 interrupts */#define HAL_KEY_SW_8_IEN IEN1 /* CPU interrupt mask register */#define HAL_KEY_SW_8_IENBIT BV(5) /* Mask bit for all of Port_0 */#define HAL_KEY_SW_8_ICTL P0IEN /* Port Interrupt Control register */#define HAL_KEY_SW_8_ICTLBIT BV(4) //修改#define HAL_KEY_SW_8_PXIFG P0IFG /* Interrupt flag at source */图4：-------------------------------------------------------------------------------------------------------------注意：将void HalKeyPoll (void)中的// if ((HAL_KEY_JOY_MOVE_PORT & HAL_KEY_JOY_MOVE_BIT)) /* Key is active HIGH */// {// keys = halGetJoyKeyInput();// }/* If interrupts are not enabled, previous key status and current key status* are compared to find out if a key has changed status.*/// if (!Hal_KeyIntEnable)// {// if (keys == halKeySavedKeys)// {/* Exit - since no keys have changed */// return;// }/* Store the current keys for comparation next time */// halKeySavedKeys = keys;// }// else// {/* Key interrupt handled here */// }图5：全部注释掉，因为它会对我们设定的按键产生干扰，具体情况我也不知道... 然后再在内模仿：if (HAL_PUSH_BUTTON1()){keys |= HAL_KEY_SW_6;}添加：if (HAL_PUSH_BUTTON8()){keys |= HAL_KEY_SW_8;}图6：------------------------------------------------------------------------------------------------------------- OnBard.c将void InitBoard( uint8 level ){if ( level == OB_COLD ){// IAR does not zero-out this byte below the XSTACK.*(uint8 *)0x0 = 0;// Interrupts offosal_int_disable( INTS_ALL );// Check for Brown-Out resetChkReset();}else // !OB_COLD{/* Initialize Key stuff */HalKeyConfig(HAL_KEY_INTERRUPT_DISABLE, OnBoard_KeyCallback); //修改此处}}改为：HalKeyConfig(HAL_KEY_INTERRUPT_ENABLE, OnBoard_KeyCallback);记得在任务初始化函数中加入RegisterForKeys( GenericApp_TaskID ); //注册按键事件图7：最后再在Coordinator.c中的uint16 GenericApp_ProcessEvent( uint8 task_id, uint16 events )添加事件及其处理函数case KEY_CHANGE:GenericApp_HandleKeys( ((keyChange_t *)MSGpkt)->state, ((keyChange_t *)MSGpkt)->keys );再在static void GenericApp_HandleKeys( uint8 shift, uint8 keys ){zAddrType_t dstAddr;if ( keys & HAL_KEY_SW_1 ){}if ( keys & HAL_KEY_SW_2 ){}if ( keys & HAL_KEY_SW_3 ){}if ( keys & HAL_KEY_SW_4 ){}if ( keys & HAL_KEY_SW_8 ) //添加自己的按键及其处理函数{HalLedSet(HAL_LED_1, HAL_LED_MODE_FLASH);}}。
