Delsys trigno and matlab connection prosthetic arm

Hello all,

I am currently trying to connect my Delsys Trigno to matlab, for matlab to recieve live SEMG signals. Does anyone know how to form this connection, or is there a certain script I must run first to build this connection? I am trying to use these signals to move a prosthetic arm in the future

Hi Zainab,

To connect your Delsys Trigno device to Matlab for live SEMG signal processing, you can use the Data Acquisition Toolbox in Matlab. For more information, please click the following link

First, ensure you have the necessary drivers installed for the Delsys Trigno device. Then, you can use the analoginput function in Matlab to create an interface for acquiring data from the device. Here is a basic example to get you started:

% Create an analog input object

ai = analoginput('winsound');

addchannel(ai, 1:8); % Add channels based on your device configuration

% Set acquisition parameters

ai.SampleRate = 1000; % Set the sampling rate

ai.SamplesPerTrigger = inf; % Acquire data continuously

% Start the acquisition

start(ai);

% Retrieve and plot the data

while true data = getdata(ai, ai.SamplesAvailable); plot(data); drawnow; end

The above snippet code will help you set up an analog input object, configures the sampling rate, and continuously acquires and plots the data from the Delsys Trigno device. You can further process this data to control a prosthetic arm based on the SEMG signals received.

Hope that answers your question.

I do apologize for my unformatted code.
