To use the board, you attach
one of the included headers to
the SCP1000 breakout board and
plug it into the interface board.
You will find an application note at
■ SCHEMATIC 1
DiosPro to collect and store data from
the SCP1000 sensor. This data will be
analyzed and then plotted on the
To plot and display the barometric
pressure, we will be using another
Sparkfun product — a graphic LCD
display for under $20. This is a 128 x
64 (B&W) display with backlight
(shown in Figure 5). Note that I added
the 20-pin header.
The LCD uses a parallel
interface and is connected to
the DiosPro microcontroller
as shown in Schematic 2.
While this may seem a bit
complicated, to make things
real simple, Kronos Robotics
has a carrier board called the
“Dios Universal LCD Carrier”
shown in Figure 6. We will be
using this carrier with a
• STEP 1: Assemble the Dios
Universal LCD carrier. Place the I/O,
Keypad, UART, and SW headers on
the top of the board and bend them
slightly so they will not interfere with
the LCD when installed.
If you use the Universal Carrier
and the SCP1000 interface shown,
then the display assembly is quite
simple to build.
• STEP 2: Assemble the interface
board for the SCP1000 using the
application note found here: www.
