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
