Add a bit info about Desy camera and a pair of debugging scripts 
1
 
Camera: 3840x5120

======

 - 5120 = 16 channels of 320 pixels each.

4
 
    * In fact two lines returned simultaneously (in each payload). So, there is 8 channels per line and 640 payloads are transferred to complete 2 lines.

5
 
    * Actually, 641. There is always 1 extra payload which is just skipped in libufodecode (starting with C0)

6
 
    * Actually, 1 (last) payload is missing for the first two rows. So, total number of payloads is (3840/2) * (640 + 1) - 32

Triggering










14



==========










15



 There is 2 bits of control register responsible for external triggering










16



    bit 16 (from 1): enables external triggering (should be 1)










17



    bit 15 (from 1): sets edge type of triggering (should be 1)

 - Start external triggering










20



    pci -w control 0x8000C201

 - Stop external triggering
