If you don’t have the screen shot utility in Accessories > Screen Shot, run this command:
sudo apt-get install gnome-utils
Run the app to capture the screen or an app window. Save to the pi folder
Useful application to test serial com ports, i.e. to test Grbl running on Arduino
sudo apt-get install minicom
minicom -b 9600 -D /dev/ttyUSB0
Use Ctrl-A and then X to exit
US keyboard mapping
The default keymapping of the pi is for UK keyboards. If you need US keymapping, you need to make the modifications outlined here.
Basically, you need to do the following
- Open a terminal window
- sudo nano /etc/default/keyboard
- Use the arrow keys to get to the layout section that says “gb” and edit it to say, for example, “us”
- You have now saved the changes, reboot:
- sudo shutdown now -r
Now, instead of seeing a hyphen with a droop on the end, you will see the tilde (~) character, etc.
