The host can read/write to these locations through the use of the CMD_COPY_SFLASH_PAGE,
CMD_PROG_SFLASH_FULL, CMD_PROG_SFLASH_PARTIAL commands. These commands are
implemented in Lumitron’s host applications to load palettes, FPGA configuration files, operational
mode descriptors, and NUC mode descriptors.
7 Remote Calibration Process
The process to complete a non-uniformity calibration is initiated with a Lumitron defined command.
After the calibration command has been issued, the embedded application communicates with the
host based on the state of the “CameraConfig.camStats.HostStatusCode” global structure member.
This variable, hereafter referred to as status code, has its state set by either the embedded application
or the host application depending upon the next step in the process.
Status codes that are used in the calibration or defective pixel detection process are as follows:
