New user and a new (to me) Picoscope. I had to try it out on some things I'm toying with in the office before going back to work.
This is the data protocol from a cheap electronic digital caliper. The 48 bit data packet is on Ch.A and the clock signal is Ch.B.
Packet length is ~850uS and the picoscope worked perfectly. Each packet contains the location of the scale stored as two 24 bit numbers. (one is relative position one is absolute.)
No built in serial decoding for this data but it is not difficult as these cheap chinese scales just use either 2*24 bits or BCD (binary coded decimal) notation.
