PARAM_TEMP0
PARAM_TEMP1Register PARAM_TEMP0 reads the temperature on the sensor board, and
register PARAM_TEMP1 the temperature inside the camera.
Example: r $908 ;reads the sensor temperature
Function group ‚LUT programming‘

Table 7 : Registers of function group 'LUT programming
Three register banks ($10000 ... $107FE for LUT1, $11000 ... $117FE for LUT2 and $12000 ...
$127FE for LUT3) are available for three user-specific LUTs. In addition to the function values y
allocated to each of the possible 1024 greyscale values x of the sensor, also a description of the
respective LUT functions is contained in these register banks.
Prior to the word-wise filling of the LUTx with function values, the respective erase sequence must be
entered into register TMFLASHx_ERASE_QUADLET. It is not possible to overwrite individual function
values in a LUT.
Example: w $10800 $6C656473;erase sequence for LUT1
w $10000 $03FE;1st function value LUT1
w $10001 $03FD;2nd function value LUT1
w $10002 $03FC;3rd function value LUT1
...
w $107FC $0002;1022nd function value LUT1
w $107FD $0001;1023rd function value LUT1
w $107FE $0000;1024th function value LUT1
The example describes what function values need to be entered in the user-specific LUT1 to generate
an inverted image (provided the missing function values are added in the above-mentioned manner).
Programming aids are recommended to be used for the generation and programming of the function
values. Two such aids are included in the software package for the CMOS industrial camera
LOGLUX
i5 CL. One is a MathCAD 2000 document which permits the function values to be easily
generated and saved in a file by defining the corresponding mathematical functions. The other is a
simple Delphi 6 program allowing the function values generated by the afore-mentioned document
to be programmed into the camera 'in one go'. Should the MathCAD 2000 application not be
available, any other suitable program can be used to generate the function values. In this case, if the
above Delphi 6 program is intended to be used for programming, the function value file should have
the following format:
• The separating character for every function value is [CRNL, carriage return + new line]. This
character has the same effect as actuating the ENTER key.
• The file must comprise 1024 unsigned integer function values.
• The value range must not exceed the limit 2
10
-1 (1023).
• The end of the file shall read [file name].LUT.
