1、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 PUS

10、 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
