DEMO MANUAL DC2026C
QUICK START GUIDE
The Linduino One comes preloaded with a DC590 emula-
tor program (called a "sketch") that allows attached demo
boards to run with the standard QuikEval GUI software.
This allows the functionality of the board to be verified
before starting firmware development. After evaluation
with QuikEval, the Linduino One can be reprogrammed
with customer code. There is a top-level demonstration
sketch for each part's library that provides a text terminal
interface to the board, demonstrating the library functions.
The Linduino One is also available as DC2026C-KIT, which
includes a DC934 as an easy to use example daughter
board. DC934 is the demonstration board for the LTC
2
dual 16-bit, I C digital to analog converter (DAC). This
board also has an LTC2422 2-channel, 20-bit, SPI inter-
face analog to digital converter (ADC) that reads back the
DAC output. Thus, this board demonstrates operation of
2
both SPI and I C interfaces, and multichannel ADCs and
DACs. The following sections describe the procedure for
installing the required software and operating the DC934
with both QuikEval software and with a terminal based
demo program.
While this manual describes operation with the DC934,
the procedure applies to other boards as well.

Manual Software Installation
1) Download LTSketchbook.zip from
docs/43958. This is the entire code base for the Linduino
board, including all demo code, libraries for individual
devices, auxiliary functions, and HTML documentation.
Extract this file to a location for working files, such as
your "My Documents" directory or "C:\Projects".
2) Note: If QuikEval is already installed, please update to
the latest version by selecting Tools → Update Pro-
gram, then proceed to step 3. If not, download and run
QuikEval from www.linear.com/software. This installs
2607
®
the QuikEval program, as well as the FTDI USB drivers
required for the Linduino One (and other Linear Tech-
nology interface boards.) Drivers are also distributed
with the Arduino IDE, but it is recommended to let
QuikEval install the drivers to ensure compatibility with
the Linduino One. You will be prompted to connect the
board to the PC during installation. Once the installation
is complete, quit QuikEval.
3) Download the Arduino Integrated Development Envi-
ronment (IDE) from either

(Version 1.6.4 is used in this manual.) This is not an
installer; no installation is necessary. Extract the contents
of this file to a convenient location for programs, such as
"C:\Program Files". The "Arduino.exe" file is the actual
program file; double-click to open the Arduino IDE.
