Sending Serial commands to Arduino via Edison

[RTang4]

Hey all,

My current stack is an Intel Edison, a sparkfun baseblock, and a sparkfun Arduino block (https://www.sparkfun.com/products/13036 SparkFun Block for Intel® Edison - Arduino - DEV-13036 - SparkFun Electronics ). The code I have uploaded to the Arduino requires a serial input (1-9600) which results in a stepper motor activating and rotating at the set speed. I want to be able to run a python script on the Edison which asks what input to enter, have the command sent to the Arduino, and the stepper motor to function accordingly. I have MRAA functioning on the Edison, I just don't know how to send the commands. Any help would be appreciated. I'm pretty new to this so the more detail the better.

Thank you!

Hi ProgrammingN00b,

If I understood you well, you want to send information from the Python script to the Arduino sketch, right? If so, I recommend you to check the following guide that explains how to share data between environments: https://software.intel.com/en-us/blogs/2015/05/05/efficient-data-sharing-using-interrupts-on-intel-e...The guide uses a Nodejs script in the explanation, but you could use a Python script instead. I hope you find it useful.Regards,Diego

Thank you Sergio this was an informative link. I was able to send and read the data through the serial port.

Do you still need help with this thread, were you able to send data?
