Memory and Persistence Considerations
Memory Considerations
The Virtual File System driver uses the driver-allocated virtual memory to store the files.
You control how much memory to be use for the board's functions.
- The amount of memory used for data storage is defined by setting the BufferSize and BufferCount elements in the configuration files of the visual encoders, the visual formatters, and the audio encoders.
- The amount of memory used for event storage is defined by setting the QueueSize element in the events files of the input lines.
- The amount of memory used for exception storage is defined by setting the QueueSize element in the exceptions file.
Persistence Considerations
The driver state and board's settings are stored in virtual memory and do not persist if the system is rebooted or shut down. Only the watchdog settings is excluded.
At driver startup, default settings are applied to all the objects.
Removing (deleting) a configuration file resets the corresponding object to default state except for the verbose/concise setting that remains unchanged.
