=== Mobita ===

'''Setup'''
* Mobita with trigger-header (MobA##et), connected to trigger interface (midi-buttonbox) via iso-trigger module.
* Trigger interface MDI IN connected to MIDI OUT on iRig2 device (midi controller)
* iRig2 device connected to main machine USB.
* Windows machine with both ethernet and wifi (use dongle and shut down regular wifi!)
* Buffer_BCI software
* TMSi Fieldtrip Polybench
* Main machine with ethernet
* Matlab
* Brainstream



'''Start-up'''
* Connect Mobita with header. 
''Blue light on Mobita should start flashing.''
* On Windows machine, setup WiFi dongle connection with mobita. Password is MOBITAxxxxxxx, where the x-es are the last seven numbers of the mobita.
''Windows should say 'Connected' or 'Verbonden'.''
* On Windows machine, double-click downloads/buffer_bci/buffer_bci/dataAcq/startBuffer
''Command window with buffer should pop-up.''
* On Windows machine, start Polybench (TSMi to Fieldtrip). In Polybench, set ‘Front-end categ’ to ‘WiFi front-ends’ and check sample frequency, then press ‘Start’.
''Buffer should start running data, Polybench should show data of first four channels.''
* On main machine, start a Matlab session, then run the code snippet below. Make sure the src variable is set according to the Windows machine’s IP address (IPv4-address). 
''Matlab should start running data.''<br />

   cd ~/bci_code/toolboxes/brainstream/core/
   bs_addpath;
   % verify src ip-address of Windows machine to find the xxx numbers!
   src = 'buffer://131.174.xxx.xxx:1972'; 
   dst = 'buffer://localhost:1973'; 
   trigger = [];
   trigger.fun = 'get_tmsi_mobita_triggers';
   trigger.cfg.channel = 36; % check number of channels of header!
   ft2ft(src,dst,trigger);<br />

* The variable ‘dst’ specifies the location at which the buffer can be found, i.e., where to find the data for the main applitcation (e.g., BrainStream project).

'''View data'''
* Start a Matlab session, and run the lines below, where the variable src is set according to the ‘FieldTrip server IP’ in Polybench.
   cd ~/bci_code/toolboxes/brainstream/core/
   bs_addpath;
   % with default preprocessing
   src = 'buffer://localhost:1973:tmsi_mobita|rjv_basic_preproc_biosemi_active2';
   % without preprocessing
   src = 'buffer://localhost:1973:tmsi_mobita|rjv_basic_preproc_biosemi_active2';
   start_viewer(src,'eeg','eeglab.blk')

'''Notes'''
* Mobita_0710130019  works with header 0730140005.
* Mobita works with only one trigger input, only at event/marker value 1.
* Trigger pulse can be viewed using quick_buffer_viewer_raw at brainstream/resources/start_scripts or StartBufferViewer at buffer_bci/dataAcq
