3.13 Command Memory
The Flare CXP cameras use non-volatile memory to store up to 8 user command sets. To
save the current camera settings to one of these user sets, first set the
User Set Selector
register to one of the user profiles, 1 to 8, and write a one to the
User Set Save
register. To
load from one of the user sets first set the
User Set Selector
register followed by a write of
one to the
User Set Load
register.
For convenience, and to easily remember what settings are programmed in a user set, the
Flare CXP cameras store a unique 32 byte name for each user set. The eight profile names
are stored in non-volatile memory and can be read or written using the
User Profile X Name
registers starting at address 0x50000000.
Also stored in the camera (in FPGA block ram) is a factory set of commands. To load the
factory profile set the
User Set Selector
register to zero and write a one to the
User Set Load
register. The factory set of commands is full resolution, normal free-run exposure in single
link CXP-3 10-bit output format.
