How do I access the log file from MATLAB

The Moku Datalogger can be configured and launched from within a MATLAB script. Once the log file is captured it can be downloaded over the network to the MATLAB PC for local analysis. This MATLAB script is an example of how to create and download the log file remotely.

%% Connect to your Moku
% Connect to your Moku and deploy the oscilloscope instrument
i = MokuDatalogger('192.168.###.###');


try


    % Enable precision mode
    i.set_acquisition_mode('mode','Precision');
    
    % Set the sample rate to 1 kSa/s
    i.set_samplerate(1e3);
    
    % Generate a sine wave on Channel 1
    % 1Vpp, 10kHz, 0V offset
    i.generate_waveform(1, 'Sine', 'amplitude',1, 'frequency',10e3);
    % Generate a square wave on Channel 2
    % 1Vpp, 10kHz, 0V offset, 50% duty cycle
    i.generate_waveform(2, 'Square', 'amplitude',1, 'frequency', 1e3, 'duty', 50);
    
    % Start the data logging session of 10 second and store the file on the RAM
    logging_request = i.start_logging('duration',10);
    log_file = logging_request.file_name;
    
    % Set up to display the logging process
    progress = i.logging_progress();
    
    while progress.time_to_end > 1
        fprintf('%d seconds remaining \n',progress.time_to_end)
        pause(1);
        progress = i.logging_progress();
    end
    
    % Download the log file from the Moku to "Users" folder
    % Moku:Go should be downloaded from "persist" and Moku:Pro from "ssd"
    i.download_file('persist',log_file,['C:\Users\' log_file]);


catch ME

    i.relinquish_ownership();
    rethrow(ME)
end


% End the current connection session with your Moku
