Video Delay – Now in Colour.

Yesterday night we finally got the delay running as it should. Great picture, stable delay:


  • Pretty satisfied with picture quality
  • Inputs need protection diodes to GND + standard synkie module input protection
  • Level shifter seems to work nicely
  • delay time is fixed, hardcoded in vhdl right now. Will try to get the rotary encoder working today

With some more clever VHDL coding this could be easily turned into a video looper by making write_enable controllable. Or a synchronized frame freezer. Or a frame synchronizer…

More to come…
