I'm starting a project to have one UNO be the "sensor" package and the other to be the display/control package. Cereal-in-the-face between them.
However I can't get Arduino IDE (app on Mac) to see both cards and assign one card to one sketch window and the other to the other. Can't see both cards in Tools|Port info at the same time.
Further if I move the USB cable to a different port on the Mac it doesn't see the board anymore. I've tried re-starting the Arduino IDE and the boards ... nothing - will only work on the one USB port (tried both UNO's there - they both work fine).
In preferences.txt I see:
serial.port=/dev/cu.usbmodem14101
serial.port.file=cu.usbmodem14101
serial.port.iserial=75638303037351F0B081
Can I add more?
Thx!
I'm not a Mac user. You can open two instances of the IDE (not: open another sketch from within a running IDE).
Simplest is probably to double-click (if that exists on a Mac) on each of the ino files that you have. Let's say you have sensor.ino and controller.ino; double-click sensor.ino will open one instance of the IDE, next double-click controller.ino will open a second instance of the IDE.
The only thing you need to do is select the correct serial port in each IDE instance.
Thanks.
Mac applications usually don't work that way. On Macs (Unix/Linux) there is one instance of the app and n instances of windows open each showing/playing/editing (whatever files, webpages, etc. and so on). And of course a given instance of the app can assign/associate different files, ports, etc. to those windows (if properly designed and implemented).
Indeed attempting to launch Arduino if Arduino is running just brings you to the running instance.
Anyway the project is on hold for now as I have other fish to fry.
