TLSR8258 SDK 如何主动采集电量

[梁修道]

使用tuya-zigbee-sdk-tlsr8258，其中sensor例程里电量是周期性自动采集的，如何变成手动采集？
即有一个函数，主动调用后开始采集，采集完成通知回调来处理数据上报

[huanghuan]

您可以参考以下方式：
1.sdk在进行周期上报电量前会通过回调

Code: Select all

bool_t dev_report_battery_by_user_data(dev_send_data_t OUT *send_data, uint8_t percentage, uint8_t voltage)

函数告知应用上报的数据信息，应用可以再该函数内自己采样并修改send data数据来实现上报数据的替换，您可以参考以下例程进行滤波等策略

Code: Select all

bool_t dev_report_battery_by_user_data(dev_send_data_t OUT *send_data, uint8_t percentage, uint8_t voltage)
{
    const battery_table_t table[] = {BATTERY_USER_TABLE};
    const uint8_t table_num = sizeof(table)/sizeof(battery_table_t);  

    const uint8_t t_msg_len = 10;/*数据长度*/
    uint16_t t_voltage_average = 0;
    uint8_t i = 0;
    uint8_t t_dp = 0;
    uint8_t *data = NULL;

t_voltage_average = average_filter_get_voltage_value();

if(table_num>1)
{
    if(t_voltage_average < table[0].voltage)
    {
        percentage = 0;
    }
    else if (t_voltage_average >= table[table_num-1].voltage)
    {
        percentage = 100;
    }
    else
    {                
        for(i = 0;i<table_num-1;i++) 
        {
            if((t_voltage_average>=table[i].voltage) && (t_voltage_average<table[i+1].voltage))
            {
                percentage = table[i].percent + \
                ((t_voltage_average-table[i].voltage)*(table[i+1].percent-table[i].percent))/(table[i+1].voltage-table[i].voltage);
                break;
            }  
        }
    }
}          

if(0xFFFF == g_private_report_str.sequence_num)
{
    g_private_report_str.sequence_num = 0;
}
else
{
    g_private_report_str.sequence_num ++;
}

data = malloc(t_msg_len*sizeof(uint8_t));
if(data)
{
    memset(data,0x00,t_msg_len);
    data[0] = (uint8_t)(g_private_report_str.sequence_num>>8);
    data[1] = (uint8_t)(g_private_report_str.sequence_num);
    data[2] = BATTERY_VALUE_DP;
    data[3] = TYPE_VALUE;
    data[4] = 0;
    data[5] = 0x04;
    data[6] = 0;
    data[7] = 0;
    data[8] = 0;
    data[9] = percentage;

    memset(send_data, 0, sizeof(dev_send_data_t));
    send_data->zcl_id = 0;//++zcl_seq;
    send_data->qos = QOS_1;
    send_data->commmand_type = ZCL_COMMAND_CLUSTER_SPEC_CMD;
    send_data->direction = ZCL_DATA_DIRECTION_SERVER_TO_CLIENT;
    send_data->command_id = TY_MODULE_DATA_REPORT_CMD;
    send_data->addr.mode = SEND_MODE_GW;
    send_data->addr.type.gw.cluster_id = CLUSTER_PRIVATE_TUYA_CLUSTER_ID;
    send_data->addr.type.gw.src_ep = 1;
    send_data->delay_time = 0;
    send_data->random_time = 0;
    send_data->data.private.len = t_msg_len;
    memcpy((send_data->data.private.data),data,t_msg_len);

    free(data);
}  

return TRUE;
}

        } 
    }
    if(t_compare_num)/*除数不能为零，为零则保留原有平均值*/
    {
       t_voltage_average = t_voltage_sum/t_compare_num; 
    }

    return t_voltage_average;
}

2.若您需要单独开启采集任务并进行数据上报，可以通过应用开启定时器，并通过 hal_adc_to_voltage();hal_adc_get_value()；相关函数进行采样，并通过dev_zigbee_send_data 函数自己进行采样数据上报。相关数据转载可以查看方法1进行参考使用
