Possible reason: Bluetooth communication issues possibly due to the bluetooth of your system trying to connect to the device. Problem: Trouble connecting device via COM port or No handshaking. The default list is 1 2 3 4 5 6 7 8 for 8 channels and similarly 1-16 for 16 channels. The Channel Gain for any channel could be 1 2 4 6 8 12 24(Default)ĭefine your own channel list. Once the experimenter plugs in the dongle, you can obtain the port name through Devices and Printers in Windows. The name of the port where the Bluetooth dongle is attached to. This parameter will decrease the number of samples per second that are actually drawn in the Source display. In case you are experiencing problems by higher sampling rates (e.g., data loss, jerky display, etc.), increase the SampleBlockSize so that you are updating the system less frequently (usually, updating the system 20-30 times per second is sufficient for most applications), and increase Visualize->VisualizeSourceDecimation. Note that more frequent updating than two times per second is not possible without altering the OpenBCI firmware. So the suggested value for sample block size is 125. For example, at 500 Hz sampling and a SampleBlockSize of 20, the system (e.g., source signal display, signal processing, and stimulus presentation) will be updated 25 times per second.įor OpenBCI Cyton the sampling rate is 250Hz and it sends data to buffer every half second. Together with the sampling rate, this parameter determines how often per second data are collected, processed, and feedback is updated. Users can see the current working condition of the hardware from Operator Log.ĭefault Parameter Configuration with 8 Channels and SampleBlockSize=125 (500ms) After the module is connected and successfully working, you can click on START.Ĩ. If you want to configure as per your own wish, click on CONFIG, else click on SET CONFIG which sets the default configuration that uses 8 channels.ħ. After running it, you will see a dialog box with following options: CONFIG, SET CONFIG, START, QUIT.Ħ. Now, go to the following directory "./BCI2000.圆4/batch" and RUN OpenBCI_Module.ĥ. Go to the following directory "./BCI2000.圆4/src/contrib/SignalSource/OpenBCI_Module" and open the file "README.txt" and perform as instructed.ĥ. If you want to use 16 channels mode, plug in the extension ("Daisy") board.Ĥ. Switch the OpenBCI board to "PC mode" from "OFF" or "BLE" mode (using a button on the right side of the board).ģ. Plug in Bluetooth dongle via USB to your system and switch its mode to "GPIO_6" if it is set to "RESET" (using a button on the left side of dongle).Ģ. The ground pin on the extension board also needs to be connected to ground.Ĭyton-Daisy Board (Cyton board with Extension board)ġ.

The index for each channel on the extension board is equal to the pin number plus 8. The pins on the extension board have the same name as pins on the main board. With an extension board present, the sampling rate will reduce to half of the original sampling rateĪnd a linear interpolation will be used for up-sampling. In order to use more than 8 channels, an extension board must be plugged in.

PC does NOT activate pull-up on RFduino pin 4 Then release the RST button, and the blue LED will blink pleasantly, announcing that the PIC is ready to accept new code. To put the PIC into bootloader mode so that it can be re-programmed, press the RST button and hold it down. The RST pushbutton is connected to MCLR on the PIC.
