Okay, a little info up front.
A friend of mine at work (thank you Brian Quinn) connected one of my iGaging Absolute DRO scale up to his O-scope.
What he found is as follows:
1. The iGaging Absolute scales are a 52 bit (Mitutoyo protocol) data set (13 digits, 4 bits per digit.).
2. Delay time for read head is 70 msecs
3. Verified clock speed is 2KHz (down from the originals at 9KHz)
4. Duty cycle remains at 20. (used for chip loading function for Tach)
Being a bit of an avid programmer as well, he proceeded to make the necessary changes to the version 3.3 on Yuriy’s Toys Touch DRO site ( http://www.yuriystoys.com/ )
While perusing the site, he noticed Ryszard’s update link. He said that version did a much better job at averaging the data sets for a more stable reading/output.
(Ryszard Malinowski has made significant upgrades to my original Arduino v3 sketch. His version handles HAL sensors and low RPM much better than the original version. The documentation and the download links can be found on his website (http://www.yuriystoys.com/p/downloads.html)
I deleted the sketch as it won't work in the current format. Getting closer and will continue to update until it works.
