Per i lettori italiani.
Ho messo in piedi un sito vetrina dove condivido le mie creazioni elettroniche.
Oggetti altamente artigianali e dilettanteschi. Talvolta brutti e fatti male.
https://www.gioele.xyz
In questo sito raccolgo e presento qualche idea e qualche realizzazione, spesso maldestramente scopiazzate, di semplici e molto artigianali oggetti elettronici fatti in casa (circuiti e roba basata su Arduino) con cui far divertire in qualche modo bambine e bambini.
E magari, perché no, stimolare la loro curiosità nei confronti di hacking, DIY, elettronica e informatica.

Arduino IDE and persistent serial port (Linux)
In the development of a little project with Arduino, I have to plug and unplug the USB cable a lot of times.
And I have a big annoyance: every time I plug the USB cable again, the port name changes from /dev/ttyUSB0 to /dev/ttyUSB1 and vice versa. So, in the IDE I have to go in Tools -> Port menu and select the right serial port every time before uploading the new sketch.
What a bore!
I've found this post, but the Arduino IDE seems that doesn't detect fancy names like /dev/arduino, but only names starting with "tty".
So my solution, in order to get a persistent name, is based on the http://hintshop.ludvig.co.nz/ blog post, but using a different port name:
sudo vi /etc/udev/rules.d/98-usb-serial.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="1a86", ATTRS{idProduct}=="7523", SYMLINK+="ttyUSB10"
Reload udev rules with:
sudo udevadm control --reload-rules -R
Now in the IDE you can select this port and it never change every time you unplug and plug the USB cable.
