【GPS】GPS的C_GNSS_RF_ELNA_GPIO_NUM_DEFAULT配置,Linux系統中GPIO的設置

GPS的GPIO配置文件html

客戶須要更改此變量C_GNSS_RF_ELNA_GPIO_NUM_DEFAULT才能覆蓋NAVRF驅動程序ELNA設置。  linux

modem_proc/gps/gnss/mgp/me/gen8/src/cgps_ext.capi

  /* Customer needs to change this variable in order to override NAVRF driver ELNA setting */ide

 

  gnss_ExternalGNSSConfigStruct   gnssz_ExtElnaCfg = post

    { GNSS_RF_HAS_ELNA, 80, NULL, C_NAVRF_NPA_RESOURCE_NAME_DEFAULT, C_PMIC_NPA_MODE_ID_RF_MODE_DEFAULT};

或者,測試

 modem_proc/gps/gnss/mgp/me/gen8/src/cgps_ext.cthis

 /* Customer needs to change this variable in order to override NAVRF driver ELNA setting */
 gnss_ExternalGNSSConfigStruct  gnssz_ExtElnaCfg = 
   { GNSS_RF_HAS_ELNA, C_GNSS_RF_ELNA_GPIO_NUM_DEFAULT, NULL, C_NAVRF_NPA_RESOURCE_NAME_DEFAULT, C_PMIC_NPA_MODE_ID_RF_MODE_DEFAULT};

 modem_proc/gps/api/gnss_api.hspa

  #define C_GNSS_RF_ELNA_GPIO_NUM_DEFAULT   98htm

    命令操做以下:(不一樣環境目錄可能會有不一樣)

    cd /sys/class/gpio  

    echo "1">export    (測試gpio1)

    cd gpio1

    cat direction(查看gpio1是否有對應的輸入輸出的字符)

    【in:輸入,out:輸出】

        echo "out">direction

    echo "1">value (該操做把gpio1置爲1)

    echo "0">value(該操做把gpio1置爲0)
