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
Libstock
website. Just download them and you are
ready to start.

6. SMD Jumpers
The current Click™ board communicates with
the main board microcontroller via SPI interface
(using ADC) or via AN line (directly connected
to the microcontroller AN pin) depending on
the position of the
J1
SMD jumper. This jumper
is soldered in ADC position. There is one zero-
ohm SMD jumper
J1
used to select whether
3.3V or 5V power supply is used. Jumper
J1
is
soldered in 3.3V position by default.
