This video is about a timing issue in the vga circuit that I’ve been avoiding talking about with the assumption that a good time to discuss it would present itself. That didn’t happen so it’s getting it’s own video now before it becomes either a blocker or something I have to hand wave and I don’t like making circuit changes that I haven’t talked about.
I do have to talk about the sprite circuit a little in planning out the changes, I also manage to loosen some wires while adding a breadboard which I have to investigate for a while, a solid example of why I’m trying to get more stuff on pcb sooner rather than later.
While the circuit change is small it’s important and is part of the process of preparing for the final circuit additions.
