6. SMD Jumpers
There are four zero-ohm resistors (SMD
jumpers):
whether 5V or 3.3V power supply is used,
and three
selecting the device address.
7. Code Examples
Once you have done all the necessary
preparations, it’s time to get your click
board up and running. We have provided
the examples for mikroC, mikroBasic and
mikroPascal compilers on our
website. Just download them and you are
ready to start.
