DEMO MANUAL DC2026A

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

interfacetotheboard,demonstratingthelibraryfunctions.

The Linduino One is also available as DC2107, which

includes a DC934 as an easy to use example daughter

board.DC934isthedemonstrationboardfortheLTC®2607

dual 16-bit, I2C 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

both SPI and I2C 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.

Software Installation

1) Download LTSketchbook.zip from http://www.linear.

com/designtools/linduino.php 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

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

http://arduino.cc/en/Main/Software or

http://www.linear.com/designtools/linduino.php

(Version 1.0.4 is used in this manual.) This is not an

installer; no installation is necessary. Extract the con-

tents of this file to a convenient location for programs,

suchas“C:\ProgramFiles”.The“Arduino.exe”fileisthe

actual program file; double-click to open the Arduino

IDE.
