I2C interface for EAW0J-B24-AE0128L encoder

This EAW0J-B24-AE0128L have 10 pins which just gives us the gray code values i.e., which are binary…
So, we need to have an I2C interface to connect it to Arduino.

For this we have a idea of using either PCF8574 or PCF8574A IC to get access to the micro controller.
Do u guys supply this interface (i.e., PCF8574 I2C) that is needed to be connected to the encoder or any other solution for it to actually control it with the micro controller.

Take a look at part PCF8574PWR

Hi Ashishjain20,

I found a GitHub entry that gives examples of how to interface the EAW ACE-128 (the EAW0J-B24-AE0128L) to an Arduino here. Looks like it gives examples using both the PCF8574 and the MCP23008, which is another I/O to I2C converter from Microchip.

Hope this helps. Good luck!
