QUICK START PROCEDURE

Various features of the DC2334A can be demonstrated by

using Linear Technology’s QuikEval Software. QuikEval is

a USB-based product demonstration and data acquisition

software meant to be used in conjunction with the DC590

that connects to individual daughter cards for specific

Linear Technology products. This software can be found

on Linear Technology’s website at:

http://ltspice.linear.com/software/ltcqev.exe

Connect the DC590 to a PC using the USB cable provided

with the DC590. Now, connect the DC590 to the DC2334A

and apply power and load according to Figure 1.

should auto-detect the DC2334A and provide the user with

a control panel.

INTERFACING THE DC2334A WITH THE DC2026

This board can also interface with the DC2026 Linduino

boardwhichispartoftheLinduinoFirmwareDevelopment

Program. The Linduino Firmware Development Program

provides users with convenient driver code, written in C,

for a wide range of LTC products. Please see the Linduino

web page for more details.

The DC2026 comes preloaded with a DC590 emulator

firmware which allows for easy interfacing with QuikEval.

Connection is done the same way as for the DC590 (Figure

1). QuikEval will launch the graphical user interface (GUI)

as it would with the DC590. The DC2026 can also be used

as a development platform, example software along with

drivers can be found on the product landing page:

NOTE: DC590 and DC2026 (Linduino) programmed with

the DC590B sketch behave the same and so are fully

compatible. This demo manual will mostly use the term

DC590 but still it can be replaced by DC2026 (Linduino).

DC2334A AS LINDUINO SHIELD

The DC2334A may be used as an Arduino/Linduino shield

by stacking it on top of the DC2026 via connectors J5-J8.

In conjunction with a LCD Keypad Shield (e.g. from

SainSmart.com, 20-011-901), this setup allows to run

the DC2334A as a stand-alone power, charge and energy

monitor without the need for a PC. A dedicated set of

DC2334A, DC2026 with tailored Linduino sketch and a
