Binary pattern jump

Hello,

I want to reproduce sequentially a total of 48 binary patterns which are stored in the internal memory. The patterns consists of a horizontal line that go down at each pattern from the top to the bottom side. Pattern 0 the line is at the top of the DMD and at pattern 47 the line in at the bottom position. The question is:

Is it possible to reproduce this sequence at the reverse direction? i.e. reproduce the same 48 patterns to move the line from the bottom to the top without changing the stored patterns? This is for an scanning application where we would like to scan in both directions (top to bottom and viceversa)

In case of that's not possible, could we for example: jump from one pattern to another one without reproducing the intermediate patterns by sending a "high frequency" trigger signal? The idea here is to jump, for example, from pattern 45 to pattern 5 by sending 7 consecutive fast trigger pulses to avoid reproducing the intermediate patterns.

Thanks in advance,

Jordi

    Yes, it is possible, for this you just need to redefine the Pattern LUT entries, and Image LUT entries.

    For example:
    Image LUT is 0,1
    Pattern LUT is 0,1,2,....23

    For reverse order
    Image LUT change to 1,0
    Pattern LUT change to 23,23,22,...0
