BrainbitSyncChannel

 

#include “csignal-channel.h

 

EEG signal synchronous data channel. Designed for synchronous data acquisition from four overlay locations (T3, T4, O1, O2). Heir to the base class of ​AnyChannel ​channels. The receipt of new data in the channel is carried out only when the device is connected and the signal pickup is started (​CommandStartSignal)​.

Description

create_BrainbitSyncChannel
