Digital Caliper Computer Interface

Digital Caliper Computer Interface can be used to log data on a spreadsheet. Report by Jeremy S. Cook @ blog.hackster.io

With a few pointers found here, he found that this data is transmitted in a continuous stream in 24 bits at 1.5 volts. He therefore level-shifted the 1.5V output to 3.3V and fed into a logic analyzer to further decode this data. With this worked out, input signals are fed into an ESP32 module on a special SAM32 board for the final(?) implementation, which also contains a Microchip SAM D51 microcontroller running CircuitPython. The SAM D51 handles sending the data to a computer, which is entered nicely into Excel!
