Hi !

I did not get any notification from the forum, so I thought you are still waiting for the Logic Analyzer to arrive .

Please download and install v1.26 on your OS. It does not matter wether you use OSX or WIN32/64.

If you connected the Logicanalyzer through USB and have installed the driver the button on the upper right should change from
"Start Simulation" to "Start". If the channels are connected to the DMD connector you should get something like on the picture attached.

Use "Save Capture" from the options menu and send me the file.

With that I should be able to add the code necessary to read the data to the PIN2DMD XL firmware .

Did anyone make a capture so far ?

I replied to you on Pinside with a couple of additional questions. But the simple answer right now is no. I just have had zero time (and not sure if I will before June 14th). I was out of town, just got back and have a crazy week ahead of me with a full schedule, just to head out of town again next weekend for another week.

I will try and squeeze in some time this week, but need those questions answered first so I can be sure of exactly what and how I need to do it.

Here is a picture of the pinout of the DMD connector

I need a capture of this connector on the attached picture.

I need a capture with logic analyzer Channel 1-6 connected to 1,3,5,7,9,11 and GND connected to pin 2

This should be the connector in your machine

Maybe Sunrise Side can take over again if you are too busy

Sunrise Side · « **Reply #26 on:** May 31, 2021, 05:54:55 PM »

I will be at my shop tomorrow and get the connections made. I need to know what OS is best to do the analyzing with?

OK . Didn't make it yesterday.
I'm hooked up and not showing any data. Please check my pictures and see what I am doing wrong.
The machine is playing normally.

Better pic

Well it works better when you click on the START tab. Have an error though

Sunrise Side · « **Reply #34 on:** June 02, 2021, 11:48:39 AM »

There is update for this. Would that help? Or do I need a newer analyzer? Or ?

Lucky1 · « **Reply #35 on:** June 02, 2021, 10:28:50 PM »

Looks good so far. Just press keep and send me the data you have recorded. Click on option -> save capture to save the data. Maybe you can upload it to dropbox or google drive. If you dont have the possibilty to upload the data you can try to send it to luckyjamann (at) gmail (dot) com

Sunrise Side · « **Reply #36 on:** June 03, 2021, 12:37:09 PM »

An update. I captured the data and sent it to Lucky1.

Sunrise Side · « **Reply #37 on:** June 06, 2021, 09:29:54 AM »

Update. The data capture I did was no good. Going to try again.

Lucky1 · « **Reply #38 on:** June 06, 2021, 10:08:07 AM »

I tried to buy a dotmation controller from ebay to do some testing with real data but unfortunately the seller refused to ship to europe :-(
I hope Sunrise Side is successful in getting some better recordings.

Good news is I just received a new recording from Sunrise Side.
Bad news is that the controller seems to introduce a glitch into the data structure,
which I currently dont know how to handle. It seems that the controller randomly adds
a bit to the 192bits sent out per row. A plasma display handles only single rows and therefore
this is not visible. My software reads all rows in one go and that would lead to a alignment problem
of some rows.

I think we have to wait until I get a controller board and maybe I can fiddle something out to make it work
