How do I access the log file from MATLAB
The Moku:Lab's 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.
%% Basic Datalogger Example % % This example demonstrates use of the Datalogger instrument to log % time-series voltage data to a (Binary or CSV) file. The remote Moku % logfile is then downloaded to the local PC/Matlab % % (c) 2019 Liquid Instruments Pty. Ltd. % %% Connect to your Moku ip = '192.168.1.68'; file_format='mat'; % Connect to your Moku and deploy the desired instrument m = MokuDatalogger(ip); %% Configure the instrument % Set the samplerate to 1000 Hz m.set_samplerate(80000); m.set_frontend(1, 'fiftyr', false, 'atten', false,'ac', false); m.set_frontend(2, 'fiftyr', false, 'atten', true,'ac', false); m.set_precision_mode(true); %% Start data logging % Stop an existing log (if any) m.stop_data_log(); % Start a new 10-sec dual-channel .MAT log to SD Card. m.start_data_log('duration',10,'use_sd','true','ch1','true', ... 'ch2','true','filetype',file_format); %% Track log progress % Wait for data log progress to reach 100% progress = 0; while(progress < 100) pause(0.5); progress = m.progress_data_log(); disp(['Progress ' num2str(progress) '%']); end m.upload_data_log(); disp(['Uploaded log file']) % Check the filename that the log was saved under fname = m.data_log_filename(); disp(['Log file completed: ' fname]); % Fetch log file from Moku pathname = sprintf('http://%s/sdcard/%s.%s',ip,fname,file_format); outfilename = websave(fname, pathname); disp(['Log saved: ' pathname]); %% Close the logging session % Denote that we are done with the logging session m.stop_data_log();
