Topic: problem with arduino interface (serial ports change) (Read 353 times) previous topic - next topic


hi   this is my 1st post so i'll try to be concise.

im trying to use my arduino Nano and UNO in my notebook (at the same time), and here comes the problem: it only lets me use one, if i try to define 1 of the serial ports (arduino UNO or nano) automatically the other also changes! :smiley-confuse:  let me show you with this screenshots:

here is the screenshots :

It would be nice to share the solution so others can benefit as well.

As crossroads says, opening two instances of the IDE has always worked for me. The trick is not to open the second source from within the first instance but by double-clicking the ino file of the second one.
If you understand an example, use it.
If you don't understand an example, don't use it.
