This is a simple tool you can use to check / ensure that the connections you have soldered on your ELMA E-37 encoder are functioning properly.
BOARD: Arduino Mega or Mega 2560PROCESSOR: ATmega2560 (Mega2560)PORT: Your Arduino Com Port
Exit the tools menu and press the arrow symbol on the tool-bar to begin the upload.
INTERPRETING THE RESULTS
You can see that Pin 2 / 3, and 4 / 5 are grouped together. These groups represent the connections for the inner and outer encoder.
When any encoder axis is turned one click, both pins should change from 0 to 1, or from 1 to 0.
If you see a mismatch in a group (For example, Pin 2 is “0” and Pin 3 is “1”), there is a connection problem present.
Likewise, if you turn the encoder one click and don’t see any changes, multiple pins could be disconnected.
The BUTTON PIN will always be “1” in it’s natural state. Pushing and holding the button pin will change it to “0” on the next update.
To restore the Echo, please use the Class Echo Updater tool and only select the Arduino firmware (you can leave the display firmware blank). Upload and the Echo should be ready to go!
