Somebody have the LA traces performed by DIO capturing the four wakestates? They don't seem to be here in the forum. He posted a few traces, but not the ones that show the different wakestates.
What signals do you want captured? A while back I decided it would be fun to have an LA so I bought one. I've captured WS1 and WS2 from my Mega ST below, it's a bit difficult to get it into WS3 and WS4 but I will power cycle until I succeed once I know what signals are of interest
Examples attached. At 400MHz I can only capture four signals, then I need to go down some in speed for every new block of signals I add until I reach the maximum of 16 at 100MHz. Of course, if the 32MHz clock isn't interesting then it should accurately get 8MHz and below with all probes used.
The .dsl files (64k captures) should be loadable in DSview* - I guess you might want to look at the end of lines instead of just the beginning as in the screenshots. Also, these were just standard medium resolution desktop lines, no fullscreens etc. I can of course do those
DE-to-LOAD 3 CPU cycles (WS2) and 6 (WS1) respectively easily seen.
