Configuration System Variables.
#include< config_obj.h >
Configuration variable objects are part of the NetBurner 3.x configuration system. The use of configuration objects facilitates a much easier method to create and store non-volatile information for both system configuration and for user application configuration and storage. They use a JSON interface so the information can be easily downloaded to save a configuration, or uploaded to configure the entire device at one time, such as in production bring-up. This includes system configuration such as IP addresses, and also any settings specific to your application.
The JSON value types include: integer, unsigned integer, float, boolean and string. There are also objects for IPv4 IP, IPv6 IP, MAC addresses, passwords, and selection lists options. In JSON everything is represented as a string, so there are object member functions to convert between values. These functions make use of the NBString class.
For customers using the 2.x tools, the User Parameter flash sector method is still available, but we do recommend converting to the new configuration system. In 3.x you have the ability to access the data through a web configuration page and also through JSON, but you can certainly choose not to use those features and treat the configuration system as internal storage, and any configuration can be done through your application just as with the 2.x tool set.
