  1. Camera: 3840x5120
  2. ======
  3. - 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
  7. Triggering
  8. ==========
  9. There is 2 bits of control register responsible for external triggering
  10. bit 16 (from 1): enables external triggering (should be 1)
  11. bit 15 (from 1): sets edge type of triggering (should be 1)
  12. - Start external triggering
  13. pci -w control 0x8000C201
  14. - Stop external triggering
  15. pci -w control 0x80008201
  16. Repeating line bug
  17. ==================
  18. - Happening with manual triggering, but do not happen in external trigger mode
