Simply right click the USB Serial Port of the OBCI board and go to Properties > Port Settings > Advanced and change the Latency Timer from the default 16 ms to 1 ms.įixing this issue should make the incoming signal much more consistent in terms of packet time intervals.
RAM requirements Recommended graphic memory or virtual ram for aero based operating systems is 256 MB min.ram -768 MB for 13. Part of this solution applies where aero / transperancy is used including d3d games. The default FTDI latency is too large for EEG applications, making the incoming signal "choppy" and seem as if its accumulating packets for about a full second before releasing them all at the same time into the serial stream. 29 Graphic/performance fix for Ubuntu was tested with Ubuntu 13.04, 12.10, and 12.04. To check it is, in fact, the OBCI board connecting and disconnecting the Dongle should connect and disconnect the COM port. If the number is not displayed next to the port name it should be visible in the properties of the port. If everything went well, your OpenBCI Board should be showing up with a COM port number.
Your board should now be recognized as a COM port. Select the "**Browse my Computer for Driver**" option and navigate to the FTDI download folder. Right click on Unidentified USB Device from the **Device Manager** tab and select **Update Driver Software**.
