Devoting different channels of the Cyton +Daisy to EEG and EMG simultaneously
@wjcroft 'The OpenBCI Cyton Board and OpenBCI Daisy Module (which plugs into the OpenBCI Cyton Board) can be used to sample up to 16 channels of brain activity (EEG), muscle activity (EMG), and heart activity (ECG). The system communicates wirelessly to a computer via the OpenBCI USB dongle using RFDuino radio modules. It can also communicate wirelessly to any mobile device or tablet compatible with Bluetooth Low Energy (BLE). The CytonDaisy Board samples data at 125 Hz on each of its 16 channels.'
Firstly, from information quoted above about the Cyton +Daisy, is it proper to infer that the OpenBCI platform is capable of simultaneously displaying data about both brain (EEG) and related or corresponding muscle (EMG) activity on a computer screen? If such an inference is proper, what would be the number of channels devoted to the monitoring of related brain and muscle activity, respectively?
Secondly, does it require technical skill and programming knowledge to set up wireless transmission of data from the Cyton +Daisy board to the dongle and computer/laptop using the so-called 'RFDuino radio modules'?

Scipio, hi. See the tutorial example of how the simultaneous EEG, ECG, EMG works. You can divide the total number of channels (16 with Daisy), any way you like. The scale factor is set in the GUI interface. EEG is maximum sensitivity (microvolts), EMG and ECG typically work in millivolts scale.

@wjcroft Thanks. I will have a look at the tutorial.
