Connecting on Linux
We get it. The square black Lenovo is still number one 😊
We assume you’re running a modern version of Linux.
Install Picocom using
sudo apt install picocom or
yum install picocom or
dnf install picocom or
pacman -S picocom or
emerge -atv picocom which ever looks familiar.
Done. It’s that easy.
Connecting to your badge on Linux
Plug in a USB-Serial board, and maybe install some drivers to get it working.
On your terminal type
ls /dev/tty.* and hit enter:
- Serial chips are usually labeled /dev/ttyUSB0
If your USB-Serial doesn’t show up in
/dev/tty*then the driver hasn’t been installed or isn’t working properly (or you have a dead USB port or a dead USB-Serial)
Connect the 3.3v and GND to the header on the back of the badge. Connect the RX of the badge to the TX of the USB-Serial, and the TX of the badge to the RX of the USB-Serial.
Picocom is a bit spartan. Start it using
picocom --imap delbs -b 115200 /dev/ttyUSB0
/dev/ttyUSB0 you should possibly use the device name you found earlier.
When you see a blank screen, press the Enter key twice. A welcoming prompt should be displayed.
? and get going in the awesome experience. Type in
a and verify the symbols you see match the symbols you see on the badge. If you get question marks in blocks, weird symbols etc, your locale is not set right.
