MT6261(MT2503)创建task流程 实例

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_EXPANSIONMSG_ID_VIB_PWM_START,MSG_ID_VIB_PWM_END,MSG_ID_NAME(VIB)#elseMSG_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

Vib_pwmsrv.c文件内容如下;

下面是一个在其他task发送消息给MOD_VIB的方法：

      ilm_ptr1 = allocate_ilm(MOD_MMI);ilm_ptr1->msg_id = (msg_type) MSG_ID_VIB_PWM_START;ilm_ptr1->local_para_ptr = NULL;ilm_ptr1->peer_buff_ptr = NULL;SEND_ILM(MOD_MMI, MOD_VIB, MMI_L4C_SAP, ilm_ptr1);
