User Data Area
8.3.17.1.
User Data Area (16K)
The user data area is a FLASH data area reserved for the user, and the user can use the area to save
algorithm factors, parameter configurations, etc.
The user data area is 16K bytes and is divided into 4 data segments, each of which is 4K bytes. The user
can access the user data area through the API interface. The data is saved to the camera flash area
immediately after being written, and the data will not disappear after the camera is powered off.
8.3.17.2.
User Data Area (512K)
In addition to the above 16KB user data area, the camera also has a 512KB ROM area for storing large
amounts of data and files. Users can access the user's data area through API. After writing, it will
immediately saved into the camera's Flash area, and will not disappear after power down.
8.3.18.
Timer
The camera only supports one timer (Timer1), which can be started by a specified event or signal (only
ExposureStart signal is supported). The Timer can configure a timer output signal that goes high on a
specific event or signal and goes low after a specific duration. And the timer is cleared when the output
signal goes low. A schematic diagram of the timer working process is as follows:
