lut_mode <mode>
Selects the LUT operational mode which are described in the following table:
Mode
Description
0
Table based using interpolation. The user has to specify a table with a maximum of 48 values.
Intended for offline calibration.
1
Fast gamma mode where the user only specifies the desired gamma value.
Can be used for gamma changes during runtime.
2
Fixed gamma mode where the user selects one of three fixed gamma tables.
8.11.3
lut_preset <index>
Selects the preset storage for the current LUT interpolator. There are up to 5 presets which can be modified.

lut_sample_master <xi_0> <yi_0> ... <xi_7> <yi_7>
Defines the sample points in a lookup table for all colors. The x-value is the input value, the y-value is output.

Yi_n

Sets up to 8 sample points at a time, up to a total of 54 for the look up definition for all colors. For setting more
than 8 points, the function can be called multiple times. In case a x-position is set twice, the previous value is
overwritten.
Remarks:
1.
When more than 54 points are defined, an error message is dumped.
2.
lut_sample_<color> command should be used to read back the current sample point. lut_sample_master will
not return sample data.
