Newbie question. I have the new Shahe 5404 DRO's as mentioned in Yuri's post https://www.yuriystoys.com/2019/01/shahe-dro-scales-html . I am following Yuriy's "Arduino Basic DRO Controller" guide https://www.yuriystoys.com/p/arduino-bas...oller.html and his "Arduino DRO DIY Build Instruction" https://www.yuriystoys.com/2013/07/ardui...tions.html
The "Arduino Basic DRO controller" shows a circuit diagram with each of the X,Y,Z DRO scales input pins as (e.g. the X scale) X-1, X-2, X-3, X-4.
X-1 goes to the Arduino 3v line
X-4 goes to GND but with a 0.1uF cap between the 3v line and GND
X-2 goes to D2 on the Arduino and is referred to as the "Clock line" in the DIY Build Instructions.
X-3 goes to D3,D4,D5 on the Arduino
My Mini-USB breakout boards have GND, ID,D+, D- VBus as outputs.
GND, VBus and probably D+ (going to D3,D4,D5) are no problem.
But which of the remaining two lines ID, D- would be regarded as the Clock Line?
