App_task_config.h (config\include\app) 64687 2018/10/19
在最下面加入;
task_index(INDX_VIB)
task_module_map(INDX_VIB, MOD_VIB)
task_name("VIB")
task_queue_name("VIB 116")
task_priority(254) //优先级
task_stack_size(1024 * 8)
task_create_function(vib_create)//任务函数
task_stack_internalRAM(KAL_FALSE)
task_external_queue_size(50)
task_internal_queue_size(0)
task_boot_mode(NORMAL_M)User_msgid_app.h (config\include\app) 23418 2018/10/19
在最下面加入支持的两个消息：
#ifdef KAL_MSGID_EXPANSION
MSG_ID_VIB_PWM_START,
MSG_ID_VIB_PWM_END,
MSG_ID_NAME(VIB)
#else
MSG_ID_RANGE(VIB, 100)
#endif
创建文件：Vib_pwmsrv.c (plutommi\service\vib_pwm) 4759 2018/10/19
在Mmi_service.mak (make\plutommi\mmi_service) 43591 2018/10/18
加入该文件，能编译该文件
