Arduino Hardware Set Up #3

Wire the LCD Shield and Encoder with interface. See hardware set up #3 how to connect LCD to Arduino UNO and see Easyeda.com files for interface scheme and PCB lay-out to connect Hengstler SSI Encoder the Arduino UNO.

Encoder

The multi turn absolute SSI encoder used with the software is a Hengstler AC58-1213AK with a data format of 25 bits. 11 bits for the current continuous angular distance in number of revolutions and 13 bits for the continuous distance in one rotation. The resolution is very high because one rotation is divided in 8192 steps. The data format is Reflected Binary Code (RBC) also know as Gray code. WIKI Gray code

Atmel set up and software

It was not possible for me to develop an Arduino Sketch with the Arduino libraries to read the encoder data with a Arduino Sketch that was fast enough. I wrote a sketch in C++ with Atmel Studio 7 and you must upload the program to the Arduino with an programmer i.e. an Atmel-Ice.

We use this Arduino set up to test SSI Encoders that are used in CyberHoists series 1. link to movie
