MXOS System Core Data Management

 

To efficiently manage system core data, mxos defines a system core data structure: mxos_Context_t,

which is used to store system core data and provides a set of core data management API functions.

1. Core Data Managment API List

 

Core Data Managment API Description
mxos_system_context_init Initialize the core data used by the mxos system framework, and the system and application configuration is read from FLASH.
mxos_system_context_get Read core data address
mxos_system_context_get_user_data Get the application configuration data address
mxos_system_context_restore Restore to the default configuration, the callback function will assign a default value to the application configuration data
appRestoreDefault_callback The application sets a default value for the configuration parameters
mxos_system_context_update Write configuration data managed by core data to FLASH

 

 

 

The main structure definition and function API interfaces are described below:

 

2. mxos_Context_t

 

 

 

 

 

 

Core data structure definition:

 

typedef struct _mxos_Context_t
{
  /*Flash content*/
  system_config_t           flashContentInRam;
  mxos_mutex_t              flashContentInRam_mutex;

  void *                    user_config_data;
  uint32_t                  user_config_data_size;

  /*Running status*/ 
  system_status_wlan_t      mxosStatus;
} system_context_t;

 

 

Among them:

  • flashContentInRam:System flash configuration parameter structure, please refer to: system_config_t
  • flashContentInRam_mutex: Flash operation mutex structure
  • user_config_data:User configuration data
  • user_config_data_size:User configuration data length
  • mxosStatus: mxos running state structure, please refer to : system_status_wlan_t

 

 

 

3. system_config_t

 

The structure definition:

 

typedef struct {

  /*OTA options*/
  boot_table_t             bootTable;

  /*mxos system core configuration*/
  mxos_sys_config_t        mxosSystemConfig;

#ifdef mxos_BLUETOOTH_ENABLE
  mxos_bt_config_t         bt_config; 
#endif
} system_config_t;

 

Among them:

  • boot_table_t bootTable:bootloader Mode table information
  • mxosSystemConfig:System core configuration structure

 

 

 

 

 

 

 

 

 

4. system_status_wlan_t

 

The structure definition:

typedef struct
{
  system_state_t        current_sys_state;
  mxos_semaphore_t      sys_state_change_sem;
  /*mxos system Running status*/
  char                  localIp[maxIpLen];
  char                  netMask[maxIpLen];
  char                  gateWay[maxIpLen];
  char                  dnsServer[maxIpLen];
  char                  mac[18];
  char                  rf_version[50];
} system_status_wlan_t;` 

 

 

Among them:

  • current_sys_state: current system state
  • sys_state_change_sem: system status semaphore
  • char localIp[maxIpLen]: system local IP address
  • char netMask[maxIpLen]: Subnet mask of the system device
  • char gateWay[maxIpLen]: Gateway information for system devices
  • char dnsServer[maxIpLen]: dns server
  • char mac[18]: MAC address of the system device
  • char rf_version[50]: RF driver firmware version of the system device
