I have added a function to power off the Myo Armband (actually, according to the official BLE specification, the 0x04 command puts the Myo into deep sleep, there is no way to completely turn the device off). I think this is a very useful feature since, without this function, you have to wait until the Myo battery is fully discharged, or use the official Myo app for Windows or Mac and turn off the device from there. The base script is the myo_raw.py modified by Fernando Cosentino, as the original script by dzhu throws some errors.
Although the original code is supposed to read the raw EMG signals measured by the sensor pods of the Myo, it actually reads rectified and smoothed EMG signals, a measure of their amplitude. The code has been modified to get the real raw signals, by suscribing to the raw EMG notification characteristics by writing to and reading from the corresponding handles listed on the Thalmic Labs BLE specification. A new function to change the color of the logo and bar LEDs has been added. The program is now able to get the battery level in the same manner that it gets the EMG, IMU or classifier data. By suscribing to the battery characteristic, the Myo sends the battery level every time its value changes.

I have committed more changes to the original code. I have implemented a method to get the real raw EMG signals, not the filtered ones that the original code receives. I have also implemented new functionalities, such as reading the battery level, changing the color of the LEDs and setting the sleep mode. |

@hananabilabd, I think Open Myo is faster than this code. I've never done a proper test, but I think its close to the 200 Hz at which data is theoretically sent from the armband. You should definitely try it. |
