Piranha Color Camera User’s Manual 55
DALSA 03-032-10211-01 5/9/2007
The LUT values are two’s complement signed integers from -
256 to +255
e.g. 7
10
= 11
12
= [0000][0000][0000][0111]
-12
10
= 0-1100
2
= [1111][1111][1111][0100]
See WFC for a description of the CRC algorithm.
Load Input LUT
Purpose: Load previously stored LUT for all taps from non-volatile
memory to FPGA SDRAM.
Syntax:
lil
Syntax Elements:
Example:
lil
Notes: Before issuing this command, select the set you wish to load
with the SSN command:
0 = Factory set
1 to 4 = User sets
5 = Selects transfer from PC
LUTs are only loaded from non-volatile memory on: power-up,
LIL, and LFS. They are not loaded by LUS.
Related Commands:
wil
Write FPN Coefficients
Purpose: Saves current values of FPN pixel coefficients that are in
FPGA SDRAM to Flash memory or a PC file.
Syntax:
wfc
Syntax Elements:
Example:
wfc
Notes: Before issuing this command, select the set you wish to write
with the SSN command:
0 = Factory set
1 to 4 = User sets
FPN pixel coefficients are loaded by LFC, LFS, and
automatically at power-up.
Coefficient use is enabled or disabled with the EPC command
Set 0 can only be written from factory mode.
Format of FPN PC
File
Provided so that user can generate their own coefficients to
send to the camera
Binary file
((2 bytes, LSB first) x (number of pixels)) x (3 colors – red,
green, blue)
32 bytes reserved
2 byte CRC-16 of previous bytes
