DWGetChannelListItem

 Data itself is opened by reserving data and time_stamp variables and then using the DWGetScaledSam-

ples function

 Color representation varies from different software, so the appropriate conversion is shown next by doing

an example plot.

 As nal steps the data le is closed by using DWCloseDataFile and the library de-initialized by calling

DWDeInit.

 If the DLL is no longer used inside MATLAB™, the unloadlibrary function frees up memory.

This demo shows basic operation and can be modied according to your own programming needs.

Using DCOM to access DEWESoft data online with MATLAB™

After installation, DS-7 is a registered DCOM component on your Windows system, giving you access to a

large number of functions, among them remote control and optionally hiding the software or loading a mea-

surement setup and accessing data online or ofine.

This same DCOM standard is used when programming your own plugins, math modules, import or export

lters or additional hardware drivers – independent from the used programming language.

Again, there are programming examples on the www.dewamerica.com webpage on the DS-7 product pages.

Example ListChannels:

 Start DEWESoft from inside MATLAB:

global h;

h = actxserver(‘Dewesoft.App’);

h.Init();

h.Visible = true;

 Build ChannelList

h.Data.BuildChannelList;

 Count all available channels

h.Data.AllChannels.Count

 Count used ones only

h.Data.UsedChannels

 Access channel with index and get Name property:

h.Data.UsedChannels.Item(0).Name
