6. SMD Jumpers
The Pressure Click™ board
communicates with the main
board microcontroller via I
SPI interface depending on the
position of the J1, J2, J3 and J4
SMD jumpers. These jumpers are soldered in
I C interface position by default. There is an
2
VCC-3.3V
option to select the alternate address with
jumper J5 in the case of I
position is logic 1).

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.
