I'm working on a project using a set of different Arduino Nano connected to a Raspberry Pi through USB. Now my question is: "how can I, from the Pi's point of view, differentiate all of those Arduino and associate them with their respective tty?"
I found some part of my answer in this question. The answering guy proposes to manually change the Arduino
MODEL_ID when compiling and to use it afterwork to identify the device. The problem is that I don't know how to achieve that.
I tried to edit the
boards.txt file to add a new board configuration with custom
pid.x (why all those 4 different values?) but after selecting my board and uploading, the
MODEL_ID still stays the same:
ID_MODEL_FROM_DATABASE=HL-340 USB-Serial adapter ID_MODEL_ID=7523
Can't I just specify somehow the
USB_PID macro to the compiler command line?
