The weather sensors: https://github.com/pypilot/pypilot/tree/master/arduino/weathersensors
Have optional buttons which perform the functions: 1) toggle main display and wind speed history 2) toggle main display and barometer history.
In history mode, the other button toggles timescale
If both buttons are held down, configuration mode is entered/exited
In configuration mode use first button to go to next item, second button to change setting.
It is possible to configure from a serial console without the buttons or screen. For this use minicom, eg: minicom -D /dev/ttyUSB0 -b 38400 and type “config” to enter configuration mode.
