在MTK中添加TASK与常用函数分析

news 来源：原创 2024/5/4 11:07:57

声明TASK的ID和MOD类型
在custom_config.h中custom_task_indx_type添加ID

如：

typedef enum {
INDX_CUSTOM1 = RPS_CUSTOM_TASKS_BEGIN,
INDX_CUSTOM2,
#if defined(__MIIPTS_TASK_SUPPORT__)
INDX_MIIPTS,
#endif
#if defined(__ELIVE_SUPPORT__)
INDX_ELIVE,
#if defined(__ELIVE_IPTV_SUPPORT__) || defined(__ELIVE_RDO_SUPPORT__)
INDX_ELIVECORE,
#endif
#endif
#if defined(__MOTION_SENSOR_SUPPORT_MMI_NEW__)
INDX_GSENSOR,
#endif
#if defined(FLASHLIGHT_LED_SUPPORT)
INDX_FLASHLIGHT,
#endif
#if defined(BCT3288_SUPPORT)
INDX_BCT3288LED,
#endif

#if defined(__OPEN_PLATFORM_SUPPORT__)
INDX_CUSTOM_OPEN,
#if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
INDX_MQQ,
#endif // #if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
#endif // #if defined(__OPEN_PLATFORM_SUPPORT__)

RPS_CUSTOM_TASKS_END
} custom_task_indx_type;

中的

#if defined(FLASHLIGHT_LED_SUPPORT)
INDX_FLASHLIGHT,
#endif
为新加ID；

在custom_module_type中添加模块类型

如：

typedef enum {
MOD_CUSTOM1 = MOD_CUSTOM_BEGIN,
MOD_CUSTOM2,
#if defined(__MIIPTS_TASK_SUPPORT__)
MOD_MIIPTS,
#endif
#if defined(__ELIVE_SUPPORT__)
MOD_ELIVE,
#if defined(__ELIVE_IPTV_SUPPORT__) || defined(__ELIVE_RDO_SUPPORT__)
MOD_ELIVECORE,
#endif
#endif
#if defined(__MOTION_SENSOR_SUPPORT_MMI_NEW__)
MOD_SC_GSENSOR,
#endif
#if defined(FLASHLIGHT_LED_SUPPORT)
MOD_FLASHLIGHT,
#endif
#if defined(BCT3288_SUPPORT)
MOD_BCT3288LED,
#endif

#if defined(__OPEN_PLATFORM_SUPPORT__)
MOD_CUSTOM_OPEN,
#if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
MOD_MQQ,
#endif // #if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
#endif // #if defined(__OPEN_PLATFORM_SUPPORT__)

MOD_CUSTOM_END
} custom_module_type;
中

#if defined(FLASHLIGHT_LED_SUPPORT)
MOD_FLASHLIGHT,
#endif
为新加MOD的类型；

在custom_config.c中的数组custom_mod_task_g中把声明的ID加入：

如：

custom_task_indx_type custom_mod_task_g[ MAX_CUSTOM_MODS ] =
{
INDX_CUSTOM1, /* MOD_CUSTOM1 */
INDX_CUSTOM2, /* MOD_CUSTOM2 */
#if defined(__MIIPTS_TASK_SUPPORT__)
INDX_MIIPTS, // MOD_MIIPTS
#endif
#if defined(__ELIVE_SUPPORT__)
INDX_ELIVE,
#if defined(__ELIVE_IPTV_SUPPORT__) || defined(__ELIVE_RDO_SUPPORT__)
INDX_ELIVECORE,
#endif
#endif
#if defined(__MOTION_SENSOR_SUPPORT_MMI_NEW__)
INDX_GSENSOR,
#endif
#if defined(FLASHLIGHT_LED_SUPPORT)
INDX_FLASHLIGHT,
#endif
#if defined(BCT3288_SUPPORT)
INDX_BCT3288LED,
#endif

#if defined(__OPEN_PLATFORM_SUPPORT__)
INDX_CUSTOM_OPEN, /* MOD_CUSTOM_OPEN */
#if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
INDX_MQQ, /* MOD_QQ */
#endif // #if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
#endif // #if defined(__OPEN_PLATFORM_SUPPORT__)

INDX_NIL /* Please end with INDX_NIL element */
};
在函数custom_comp_config_tbl中添加TASK的实现函数和TASK的信息声明

如：

{
/* INDX_CUSTOM1 */
{"CUST1", "CUST1 Q", 210, 1024, 10, 0,
#ifdef CUSTOM1_EXIST
custom1_create, KAL_FALSE
#else
NULL, KAL_FALSE
#endif
},

/* INDX_CUSTOM2 */
{"CUST2", "CUST2 Q", 211, 1024, 10, 0,
#ifdef CUSTOM2_EXIST
custom2_create, KAL_FALSE
#else
NULL, KAL_FALSE
#endif
},
#if defined(__MIIPTS_TASK_SUPPORT__)
{"MiiPTS", "MiiPTS Q", 212, 1024*4, 10, 0, miipts_task_create, KAL_FALSE},
#endif
#if defined(__ELIVE_SUPPORT__)
{"ELIVE", "ELIVE Q", KAL_PRIORITY_CLASS17+2, 1024*3, 80, 0,
Elive_create, KAL_FALSE} ,
#if defined(__ELIVE_IPTV_SUPPORT__) || defined(__ELIVE_RDO_SUPPORT__)
{"ELIVECORE", "ELIVECORE Q", KAL_PRIORITY_CLASS17+4, 1024*3, 20, 10,
EliveCoreTask, KAL_FALSE} ,
#endif
#endif

#if defined(__MOTION_SENSOR_SUPPORT_MMI_NEW__)
/* INDX_GSENSOR */
{"Gsensor", "Gsensor Q", 195, 1024, 20, 10,
SC_gsensor_create, KAL_FALSE},
#endif
#if defined(FLASHLIGHT_LED_SUPPORT)
/* INDX_FLASHLIGHT */
{"FLHLT", "FLHLT Q", 200, 1024, 10, 0,
SC_flashlight_create, KAL_FALSE},
#endif
#if defined(BCT3288_SUPPORT)
/* INDX_BCT3288LED */
{"BCT3288", "BCT3288 Q", 200, 1024, 20, 0,
SC_BCT3288Flashlight_create, KAL_FALSE},
#endif

#if defined(__OPEN_PLATFORM_SUPPORT__)
{ "CUSTOPEN", "CUSTOPEN Q", 220, 4096, 64, 0, Open_TaskCreate, KAL_FALSE },
#if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
{ "MQQ", "MQQ Q", 212, 4096, 100, 10, mqq_create, KAL_FALSE },
#endif // #if defined(OPEN_CUSTOM_PRODUCT_QQ_DOWN_07A) && !defined(WIN32)
#endif // #if defined(__OPEN_PLATFORM_SUPPORT__)

}

中的

#if defined(FLASHLIGHT_LED_SUPPORT)
/* INDX_FLASHLIGHT */
{"FLHLT", "FLHLT Q", 200, 1024, 10, 0,
SC_flashlight_create, KAL_FALSE},
#endif
如果TASK需要与别的TASK交互，要使用消息，消息ID在文件custom_sap.h中定义，该头文件被包含在文件stack_msgs.h中，最终合并入msg_type枚举中。

如：

MSG_ID_CUSTOM1_CUSTOM2 = CUSTOM_MSG_CODE_BEGIN,
MSG_ID_CUSTOM2_CUSTOM1,
#if defined(__MIIPTS_TASK_SUPPORT__)
MSG_ID_MIIPTS_ENCODE_REQ,
MSG_ID_MIIPTS_ENCODE_CNF,
MSG_ID_MIIPTS_DECODE_REQ,
MSG_ID_MIIPTS_DECODE_CNF,
#endif // __MIIPTS_TASK_SUPPORT__
#ifdef __ELIVE_SUPPORT__
MSG_ID_ELIVE_BASE,
MSG_ID_ELIVE_END = MSG_ID_ELIVE_BASE + 50,
#endif
#if defined(__ALLKEY_EINT_FOR_KEYBOARD__)
MSG_ID_ALLKEYBOARD,
#endif
#if defined(__MOTION_SENSOR_SUPPORT_MMI_NEW__)
MSG_ID_GSENSOR_CHECK_START_REQ,
MSG_ID_GSENSOR_CHECK_STOP_REQ,
MSG_ID_GSENSOR_CHECK_ROTATE_IND,
#endif
#if defined(FLASHLIGHT_LED_SUPPORT)
MSG_ID_FLASHLIGHT_PLAY_REQ,
MSG_ID_FLASHLIGHT_STOP_REQ,
#endif
#ifdef __MMI_IMAP__
MSG_ID_IMAP,
#endif
#if defined(FIVE_CLAM_SUPPORT)
MSG_ID_FIVE_CLAM_SUPPORT,
#endif
#if defined(FOUR_CLAM_SUPPORT)
MSG_ID_FOUR_CLAM_SUPPORT,
#endif
#if defined(E73_TWO_CLAM_SUPPORT)
MSG_ID_TWO_CLAM_SUPPORT,
#endif
#if defined(BCT3288_SUPPORT)
MSG_ID_BCT3288FLASHLIGHT_LEFTKEY_PRESS,
MSG_ID_BCT3288FLASHLIGHT_RIGHTKEY_PRESS,
MSG_ID_BCT3288FLASHLIGHT_UPKEY_PRESS,
MSG_ID_BCT3288FLASHLIGHT_DOWNKEY_PRESS,
MSG_ID_BCT3288FLASHLIGHT_RIGHT_ROTATE,
MSG_ID_BCT3288FLASHLIGHT_LEFT_ROTATE,
MSG_ID_BCT3288FLASHLIGHT_MP3_EFFECT,
MSG_ID_BCT3288FLASHLIGHT_STOP_REQ,
MSG_ID_BCT3288FLASHLIGHT_ROTATE_CNF,
#endif
中的

#if defined(FLASHLIGHT_LED_SUPPORT)
MSG_ID_FLASHLIGHT_PLAY_REQ,
MSG_ID_FLASHLIGHT_STOP_REQ,
#endif
再看TASK函数的实现和调用：

kal_bool SC_flashlight_create(comptask_handler_struct **handle)
{
static const comptask_handler_struct custom_handler_info =
{
SC_flashlight_task_main,/* task entry function */
SC_flashlight_init,/* task initialization function */
NULL, /* task configuration function */
NULL, /* task reset handler */
NULL, /* task termination handler */
};

*handle = (comptask_handler_struct *)&custom_handler_info;
return KAL_TRUE;
}

task的处理函数，主要是获取TASK的ID函数kal_get_my_task_index和获取消息内容函数receive_msg_ext_q：
void SC_flashlight_task_main(task_entry_struct * task_entry_ptr)
{
ilm_struct current_ilm;
kal_uint32 my_index;

kal_get_my_task_index(&my_index);

while(1)
{
receive_msg_ext_q( task_info_g[task_entry_ptr->task_indx].task_ext_qid,
&current_ilm);
stack_set_active_module_id( my_index, current_ilm.dest_mod_id);
if(current_ilm.msg_id==MSG_ID_FLASHLIGHT_PLAY_REQ)
{
//ET6204_init();
SC_et6204_play(&current_ilm);
}
else if(current_ilm.msg_id==MSG_ID_FLASHLIGHT_STOP_REQ)
{
StopTimer(LED_FLASH_TIMER);
ET6204_ALL_OFF();
Poweroff_ET6204();
}
free_ilm( &current_ilm);
}
}

初始化函数，进入该TASK里需要初始化的全局变量等：

kal_bool SC_flashlight_init(task_indx_type indx)
{
ET6204_init();
return KAL_TRUE;
}

消息处理函数，主要是收到消息的处理函数，掌握et6204_light_play_ind的定义与使用：

void SC_et6204_play(ilm_struct *ilm_ptr)
{
kal_uint16 et6204_display[7];
int i;
et6204_light_play_ind *play_data = (et6204_light_play_ind *)(ilm_ptr->local_para_ptr);

ET6204_POWER_HIGH;
ET6204_ALL_OFF();
if (get_phnset_led_setting() == 0)
{
ET6204_ALL_OFF();
Poweroff_ET6204();
return;
}

if(play_data->type == 0xf0)
{
et6204_incoming_flag=TRUE;
flash_count = 0;
et6204_incoming_number[et6204_incoming_length] = 0x30+10; //jacky added
et6204_incoming_length ++;
mmi_incoming_start_et6204_ind_nubmer();
return;
}
/*else if(play_data->type == 0x02)
{
et6204_audioplayer_flag = TRUE;
mmi_audioplayer_start_et6204_ind();
return;
}*/
else
{
g_led_count = 0;
g_ec6204_type = play_data->type;
g_ec6204_play_num = play_data->play_num;
mmi_start_et6204();
}
}
消息发送，主要是如何填充消息和发送函数OslMsgSendExtQueue：

void mmi_et6204_stop_display()
{
MYQUEUE Message;
et6204_light_play_ind *et6204_play_req;

ET6204_POWER_LOW;
et6204_incoming_flag = FALSE;
et6204_poweron_flag = FALSE;
et6204_audioplayer_flag = FALSE;
/*----------------------------------------------------------------*/
/* Code Body */
/*----------------------------------------------------------------*/
Message.oslMsgId = MSG_ID_FLASHLIGHT_STOP_REQ;
et6204_play_req = OslConstructDataPtr(sizeof(et6204_light_play_ind));
et6204_play_req->type= 1;

Message.oslDataPtr = (oslParaType*) et6204_play_req;
Message.oslPeerBuffPtr = NULL;
Message.oslSrcId = MOD_MMI;
Message.oslDestId = MOD_FLASHLIGHT;
OslMsgSendExtQueue(&Message);
return;
}
void mmi_et6204_start_display(kal_uint8 type,kal_uint8 play_num)
{
MYQUEUE Message;
et6204_light_play_ind *et6204_play_req;
//kal_prompt_trace(MOD_BMT,"mmi_et6204_start_display::");
/*----------------------------------------------------------------*/
/* Code Body */
/*----------------------------------------------------------------*/
StopTimer(LED_FLASH_TIMER);
Message.oslMsgId = MSG_ID_FLASHLIGHT_PLAY_REQ;
et6204_play_req = OslConstructDataPtr(sizeof(et6204_light_play_ind));
et6204_play_req->type= type;
et6204_play_req->play_num= play_num;

Message.oslDataPtr = (oslParaType*) et6204_play_req;
Message.oslPeerBuffPtr = NULL;
Message.oslSrcId = MOD_MMI;
Message.oslDestId = MOD_FLASHLIGHT;
OslMsgSendExtQueue(&Message);
return;
}
