Adaptive Interfaces is introducing a new product line! Add-On
boards for the Raspberry Pi computer and other SPI based controllers.
With the popularity of the Raspberry Pi computer and similar control computers in the
engineering and hobbyist communities, we are now focussing our design efforts on a series of
accessory boards to expand the capabilities these already wonderful devices. Our first
accessory board, the DAAC-100, adds a multitude of electronic functions to the Raspberry Pi.
Other boards with an SPI port can also control the DAAC-100.
The DAAC-100 "Data Acquisition and Control" board adds 8 Voltage Measurement (ADC) Channels,
3 Voltage Sources (DACs), 2 Pulse Width Modulation Outputs, a 75 Hz to 1.2 MHz Oscillator
Output, 8 GPIO Lines, 2 Relays and 6 Relay Drivers to the Raspberry Pi and any other type of
control computer with a Serial Peripheral Interface (SPI) bus. The DAAC-100 is designed to
attach directly to the Raspberry Pi and be powered with its +5V supply. The DAAC-100 is
an affordable Electronics Test Bench.
The Raspberry Pi community is an "Open Source" community. Any code we write to
support the Raspberry Pi will be free for all to view and use and be available on our website.
To help everyone get started with the DAAC-100 and the Raspberry Pi, we have written a
Graphical User Interface (GUI) "Dashboard" that can be run from the RPi's "Raspbian" OS
using a terminal command line.
Writing the DAAC-100 "Dashboard" program, in C/C++, required a lot of "Bare-Metal"
hacking. We learned a lot about the inner workings of the BCM2836 chip and the use of
memory mapping to access registers. In the near future, we will post articles to our website
that detail things we have learned about the Raspberry Pi. We also hope to start a blog where
other users of the Raspberry Pi can share code, ideas and questions.
Adaptive Interfaces provides smart digital instruments for
Experimental, Home Built and Light Sport aircraft.
Our goal is to make high quality instruments that offer high functionality while
providing information to a pilot in a simple, easy to read way. The instruments
use standard 2-1/4 inch mounting holes and have bright, high-visibility LED displays that
are easy to read and provide active notification of conditions that may require the pilot's
attention. All instrument graphics and legends have internal, adjustable backlighting
for ease of reading at night. We want you to spend more time enjoying your flight and
less time monitoring instruments.
The instruments are designed in a way that makes them easy to adapt to existing
aircraft panels. They are an ideal way to design or upgrade an instrument panel
without the cost or complexity of an all-in-one system monitor. If your panel already
has an all-in-one monitor, these instruments offer redundancy for monitoring critical systems
and eliminate single point-of-failure issues.
Adaptive Interfaces instruments are supported with pre-wired cable assemblies, detailed
user manuals and demonstration videos. We also offer telephone and e-mail support for any
questions, issues or suggestions.
