Video Looper
You are viewing an old revision of this post, from October 26, 2013 @ 10:11:19. See below for differences between this version and the current revision.
Just by deactivating the write command you can easily turn the video delay module into a video looper.
Actually there is no need to seperately refresh the DRAM, because every byte gets read every other second anyway – free auto refresh when the bank is recharged. For loop cycles of at least 3 seconds this seems to work (and with analog video we’re not that picky if sometimes a bit in the stream gets corrupted…) . We had the same loop running for hours without any visual degradation. cool.
