从Zigbee协议栈底层添加自己的按键配置.doc

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 off osal_int_disable( INTS_ALL ); / Check for Brown-Out reset ChkReset(); 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;
