SDI interface in Edison

[AAl-M]

Hello,

I have been using Arduino UNO to connect environmental sensors and read their data on SDI-12 interface. I'd like to switch from UNO to Edison but I am not sure whether Edison has an SDI-12 interface.

I will appreciate if you can confirm whether this is possible or not, and whether there is any library that supports this communication similar to SDIserial used with UNO!

Thanks in advance

Hi aafm32,

The Edison module doesn't have a SDI-12 interface so it wouldn't be possible to connect a device that uses such interface.

I've checked the SDISerial library for Arduino (https://github.com/joranbeasley/SDISerial GitHub - joranbeasley/SDISerial: An SDI-12 Serial Library for Arduino) and it seems that the library is based on the SoftwareSerial library. Unfortunately the SoftwareSerial library is not supported by Edison, consequently the SDISerial library is not supported either.

Regards,

Diego

Thanks a lot Diego for the useful explanation.

Is it possible then to read data on DDI serial communication protocol? This should be a one way transmission of data frim sensor to node based on 8n1.

Hi aafm32,

I'm not familiar with the DDI serial protocol, so I'm not sure if that would be possible. Anyhow, if the example code, or method you plan to use is based on the SoftwareSerial library, it won't work because this library is not supported by Edison.

On the other hand, the suggestion provided by Vincenze seems to be the easiest one. You might want to give it a chance.

The easiest way to implement the protocol is to get a cheap Arduino Micro or Nano board and connect it to the Edison through the USB port or via a Serial port using a level translator. Program the Arduino board to receive data from sensors and transfer it to the Edison.

Look, this guy created an SDI-12 to USB converter using Arduino https://liudr.wordpress.com/category/arduino/ Arduino | Liudr's Blog

Thanks Vincenze, I will give it a try as see how it will go
