Cheap Idea for a DRO

[1113562]

OK I have done a test on the BCD vernier which is a Workzone 6" bought from Lidl or Aldi, can't remember which. I have attached an image of the state diagram.

It starts always at power up in Slow Read mode. To get from switch on to Fast Read (F.T) needs a Data then a Clock Pulse. To Zero at power up on route to F.T then its Clock then Data then Clock. When in F.T. to Zero needs a Data then CLock then Data then Clock. There are other states as shown in the diagram that are of no interest to our use I suggest.

This version of Vernier seems to be virtually the same state diagram as that on the YADRO site but they do not show some of the hold states.
