2.4.4.3.4 Pattern Display LUT Reorder Configuration

The Pattern Display LUT Reorder Configuration command reorders the lookup table (Pattern Display LUT) so that the patterns stored in memory are displayed in the order defined by this command. Before executing this command, stop the current pattern sequence. This command is only applicable in Pre-stored Pattern Mode and Pattern On-The-Fly Mode.

Patterns can be referenced in any order and can be repeated in the Pattern Display LUT. Moreover, a subset of patterns stored in the DLPC900 pattern memory can be referenced.

NOTES:

  • The default display order must be set by issuing a Pattern Display LUT Configuration command before this command can be used.
  • The pattern index numbers used must be in the set of patterns defined by the Pattern Display LUT Configuration command (that is, must be less than or equal to the number of entries - 1 defined by the Pattern Display LUT Configuration command).

BYTE BITS DESCRIPTION RESET TYPE
1:0 10:0 Number of Reorder LUT entries (NR):
  • range 1 through 1024 (for DLP5500 DMD)
  • range 1 through 512 (for all other DMDs)
 d0 wr
1 = One entry
2 = Two entries
…
  • up to 1024 entries (for DLP5500 DMD)
  • up to 512 entries (for all other DMDs)
5:2 31:0 Number of patterns to display (NP):
  • Set = 0 to repeat the sequence indefinitely
  • Set = Number of patterns to display(1)
 d0 wr
7:6 15:0 Pattern index number to be displayed first d0 wr
9:8 15:0 Pattern index number to be displayed second d0 wr
… … …
… 15:0 Pattern index number to be displayed in nth position d0 wr
NOTE: N = number of LUT entries (NR) in [BYTE 1:0]
NOTE: the Pattern index to be displayed must be <= number of entries - 1 defined in 0x1A31. In other words the pattern must exist in the Pattern Display LUT
(1) The number of patterns in the Pattern Display Reorder LUT Configuration to display (NP).
Note: Set this equal to the Number of Pattern Display LUT entries (NR) to display the sequence once. Any number can be entered here to display the sequence multiple times. The pattern will display floor(NP/NR) times and any remainder (R) will display the first R Pattern Display LUT Reorder entries. For example if NP = 157 and NR = 50 the Pattern Display LUT Reorder sequence will display three times followed by the first seven patterns defined in the Pattern Display LUT Reorder sequence.

Input Trigger considerations:

Patterns with input triggers, as defined by the Pattern Display LUT Definition commands, are attached to the pattern. Therefore the system waits for a trigger whenever the pattern index number is referenced in the re-ordered Display Pattern LUT. Moreover, the pattern that originally preceded the triggered pattern in the default Display Pattern LUT order displays 105 µs of dark time at the end of it regardless of where it appears in the re-ordered Display Pattern LUT. In addition, if a pattern that was not preceding the triggered pattern in the default Display Pattern LUT order is placed immediately in front of the triggered pattern, the last bit pattern of that pattern displays until the trigger is received.

There are several methods that can be employed to manage this behavior:

  • Consider the triggered pattern and the pattern preceding it in the default Display Pattern LUT order as a set that must be kept together.
  • Add a 1-bit all-black pattern with the shortest duration allowed preceding the triggered pattern in the default Display Pattern LUT order. See Minimum Exposure Times in Any Pattern Mode for the correct shortest duration for the current DMD. Consider these patterns as a set that must be kept together.
  • Add a 1-bit all-black pattern with the shortest duration allowed followed by a triggered 1-bit all-black pattern and remove the trigger from the pattern originally to be triggered in the default Display Pattern LUT order. These two patterns become a versatile trigger set that can be used repeatedly wherever a trigger is desired. Since the triggered pattern is black, even if your exposure integration begins with the triggered black pattern there is no additional light contributing to your exposure.
