my camera cycles through displaytype cases (0,1,...7) in lib.c
This ocurred for the old value of displaytype 0x95e4....I am wondering if this variable is indexing one of eight buffers?
FWIW, you could try to find out if there's any correlation between the fw variable and the frame buffers.
This utility allows sampling up to 6 words in the camera's memory, with up to 500 samples/second speed. The first word to sample would be the fw variable, the rest would be the first word of 5 consecutive buffers - just make sure the viewport data is changing constantly while sampling.

I ran the suggested utility....not sure it makes sense but there is variation at least partly correlated with the indexing variable: (full sheet attached)
   Maybe just random....

It would be useful if the utility did not output spaces after the commas... ::)

Edit1: interesting that the index variable seems to cycle to the next value every 20 ms, never? missing...almost like it is synchronized with the monitor....

I'd say your index variable is not related to those framebuffers.

Wish fulfilled. Also added 2 new sampling rates (200/s and 300/s), hopefully one of them will work for you too.

10 per sec works in smp mode. It's a mystery why dmp mode works at 1 per second.
DMP mode uses a cycle time of 94 milliseconds (chosen arbitrarily, so it's not a multiple of 10). The display refresh is asynchronous, which makes DMP appear as choppy.

Is Edge Overlay module works properly here?
On my EOS M3 it's not ok.
I suspect that this is because new viewport pixel formats are stil not impemented in main CHDK branch

Yes, we need to implement code to process the new pixel format for Digic6.  I think this is necessary for Motion detect and Zebra as well.
Looks to me like edgeoverlay could be implemented with a small hack to edgeoverlay.c/ function average_filter_row. Maybe keyed on THUMB_FW or some other variable in platform_camera.h.

That being said, while the likes of reyalp, srsa and others have probably thought a lot more abou what is  the best approach than I have, it does look like it's not too difficult to customize each module to deal with the new viewport pixel format.
Edit:
Looked further...it's difficult..it looks like you need to support core/gui_draw.c digic6 functions which aren't there yet for edgeoverlay..motiondetect might be easier.

One of the difficulties is that parts of the CHDK code still expect a one byte/pixel overlay. Some routines (maybe zebra, edge overlay) save and restore parts of the overlay during their activity - that is currently impossible on D6 (the overlay data not only has a different pixel format, it also has opacity information in a separate buffer). And of course, the drawing routines need to be optimized for greater speed. All this would have to be solved before "fixing" zebra and edge overlay.

I am a noob. And just bought a SX60. Have been using CHDK on SX50 and loved it.

Can I safely assume there is no current way to use CHDK on SX60 ? Or if there is can someone be helpful where the instructions are ?

Would greatly appreciate the help.

There are test builds posted earlier in the thread. I'd suggest going back through the posts until you find the most recent one.

Note that quite a few features are not implemented yet, most stuff that relies on the display data like histogram, zebra, motion detection etc.
