Myo SDK MATLAB MEX Wrapper

Access data from Thalmic Labs' Myo Gesture Control Armband in m-code and Simulink!

Thalmic Labs' Myo Gesture Control Armband (myo.com) features an Inertial Measurement Unit (IMU) and 8 surface Electromyography sensors (sEMG) in addition to a Windows SDK that allows developers to obtain access to this data!

On the surface, this package contains a simplified m-code class, MyoMex, that enables MATLAB users to stream data from one or two Myo devices at 50Hz (IMU and meta data) and 200Hz (EMG) with only 1 command! Note that EMG data is not available when using two devices due to hardware/software limitations.

mm = MyoMex(); % Upon construction, MyoMex starts accumulating streaming data in its myoData property
m = mm.myoData; % get MyoData object
% Data is now being pushed into log properties of m named,
% quat_log, gyro_log, accel_log, emg_log, etc.
% Data acquisition is non-blocking, too!
mm.delete(); % clean up

The IMU data includes estimated quaternion (orientation), three-axis gyroscope (angular velocity), and three-axis accelerometer (linear acceleration).

The sEMG data includes 8 raw data channels plus the output of Myo's built-in gesture detection.

Here are some of the things that you'll find in this package,

* README.txt - Step-by-step instructions for prerequisite configuration
* install_myo_mex() - installation tool
* build_myo_mex() - MEX-file build tool
* MyoMex_Quickstart - Quickstart guide script with example code and liberal comments
* MyoMexGUI_Monitor - GUI implementation of streaming data with visualization of all available data

New Simulink support includes MEX C/C++ S-Function block and other supporting utility blocks that support two following configurations:

* One Myo - EMG disabled
* One Myo - EMG enabled
* Two Myos - EMG disabled

The Simulink block data outputs mirror the data available from MyoData in m-code. The data is streamed in soft real-time. Thus, Simulink Desktop Real-Time is required to synchronize the model with the system clock.

This is being developed on one machine configuration: MATLAB R2013a; Windows 7 64-bit; VS2012 Pro
