Board Setup and Use
2.1 SW1 Switch Configuration
It is important to note that only one of the sensors can be used at a time. That means only one of the 8 switches in SW1 should be
moved to the left at a time. Each of the first 5 switches selects a different sensor on the board. The sixth position selects a prototype
area, the seventh selects an external expansion connector compatible with the silicon labs postage stamp boards while the last is not
used.
It is important to note that whenever the user wants to switch between sensors the board must be reset and the software started. This is
because only the SDA SCL line is switched by SW1 and a sensor that has set up could be generating interrupts when you want to
switch to another sensor.
