The serial interface provided by Arduino can be utilized by many software packages that feature serial communication libraries. Are questions on setting up the serial connection, from such software with the Arduino, on-topic?

1 Answer 1


I would say no. Arduino really has nothing to do with it. It's all configuration in the 3rd party software to match the Arduino's configuration.

This may be on topic:

How do I configure my Arduino's serial port with the following settings?

This is not:

How do I configure this software to communicate with a device which uses the following serial configuration?

See how I said "device" instead of "Arduino"? Changing Arduino there doesn't change the question in any way.

I realized you may be referring to questions like How can I communicate Arduino to Matlab. Still, the underlying question is how to interface a serial device with MatLab, which really has nothing to do with Arduino specifically.

Even in that question, the first comment is

Do you need help writing the code for the Arduino, or help writing MATLAB code to read data input from the serial stream?

  • In general, I'd agree. If it's clear that the question is nothing to do with Arduino then it's off-topic. Judging by Arduino questions on SO though, the distinction may not always be clear. E.g. a lot of hobbyists seem to like connecting Android or Processing to Arduino via serial, and when they have a problem it may not be obvious (at least to them) where that problem actually lies.

  • I was referring to this as well..

  • @sachleen - here's one force-migrated here from SO that is ultimately another example of "how do I write a program on my desktop to talk to my arduino" that thus probably belongs there rather than here. arduino.stackexchange.com/questions/1358/… May 1, 2014 at 23:15
