COM port number woes....

[leharlgdc]

Hi ,

I am connecting 4 arduino boards on the raspberry pi , and reading serially the data coming from the arduinos , now each time i turn off my rpi and then on , the COM port number exchanges , how can i make the port numbers constant ?

I've split this to a new thread, as it was added to a (mostly) unrelated one.

This stack exchange topic explains a few methods.

The basic concept is to use udev rules to assign the port aliases.
