HEXIWEAR---Sensor

Sensor

硬件

從下圖原理圖中可以看出，3個sensor掛在I2C0，3個sensor掛在I2C1.

程序如何處理Sensor的數據採集

/**
 * retrieve(取回) data from various sensors
 * @param param task parameter, currently unused
 */
static void sensor_GetData( task_param_t param )
{


        /**
         * read, format and insert data into the packet
         */
       switch ( sensorToSend )
        {
            /**
            * Battery level
            */

            case packetType_batteryLevel:
            {
            }
        }

        /** blink a LED if needed */

        if ( SEND_NO != isReadyToSend )
        {

         }

        /**
         * finish with packet formation and push the packet
         */

        switch( isReadyToSend )
        {
            case SEND_YES:
                // format data

                // add trailer byte, denoting the packet end

                // push data

                // wait

                // goto next sensor
                NextSensor(sensorToSend);
                break;
         }
}

sensor_driver.c 中：

sensor_GetData通過NextSensor(sensorToSend);輪詢各個sensor；
switch ( sensorToSend )中各個case對應不同sensor，通過調用各個模塊的驅動函數來讀取相應sensor數據。
