I have connected the board with Arduino Uno and configured it as per the specifications given in the link below.<br />http://www.protocentral.com/blog/getting-started-with-ads1292r-ecgrespiration-shield-n9<br />Using the BrainBay configuration file loaded in BrainBay and connecting the board through Arduino to PC, the signal acquired in BrainBay is same, a simple line with no variation in the oscilloscope display. I tried to take ECG signal many times but same display was obtained each time. Also there is some data transmission taking place from Arduino to PC as the TX light of the Arduino starts blinking when I select connect COM port in BrainBay but nothing gets displayed on the Oscilloscope.<br />Hope for your reply soon,<br />Thank You.

This is similar to ADS1299, but with lower performance and only two channels. I replicated the OpenBCI packet format and used the BrainBay OpenBCI device to visualize the signal. Here is the project and an ECG signal of my heart :)<br />http://bois083.wordpress.com/lucid-dreaming-device/version-5-0/the-prototype/<br /><br />Your blog helped me a lot.

OpneBCI no longer needs to be put into a special output mode.<br /><br />The standard OpenBCI format is defined both in the rduino code on OpenBCI's Git (see ADS1299Mananger) and it is defined in the Wiki on Git:<br /><br />https://github.com/OpenBCI/OpenBCI/wiki/Data-Format-for-OpenBCI-V1-and-V2<br /><br />Finally, each channel is 4 bytes because, internal to the Arduino we expand the 24-bit number from the ADS1299 into a standard int32. That enables some filtering or other processing of the data on the Arduino, if desired. Then, when the Arduino goes to send it out the serial port, I kept it as a standard 4-byte int32 instead of truncating to a 24-bit number.<br /><br />It is possible that we'll switch back to sending just a 24-bit number when we move to OpenBCI V3. It'll all depend upon the throughput that we get on Bluetooth.<br /><br />Hope this helps!Chiphttps://www.blogger.com/profile/10352943033779293161noreply@blogger.comtag:blogger.com,1999:blog-7276377053120174333.post-21099240451875812292014-03-21T11:40:37.154-04:002014-03-21T11:40:37.154-04:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/05594611727147059236noreply@blogger.comtag:blogger.com,1999:blog-7276377053120174333.post-11267042004352141582014-03-21T11:40:08.513-04:002014-03-21T11:40:08.513-04:00Hi Chip,

It's great that BrainBay got a new driver for 8 channels 24 bit data. However, I don't have any documentation for this driver rather than Chris code on Github<br />https://github.com/ChrisVeigl/BrainBay/blob/c0121b247a60bada948a8351b1c1fdb682b35081/src/ob_eeg.cpp<br /><br />Could you please have a post about this? The protocol, a sample data package, some code maybe... The OpenBCI code in GitHub is the 6 channel 16bit one.<br />I'm not clear about the package lenght and Framenumber...And why it is 4 bytes per channel...<br /><br />Thanks a lot! <br /><br />Anonymoushttps://www.blogger.com/profile/05594611727147059236noreply@blogger.comtag:blogger.com,1999:blog-7276377053120174333.post-91699365906330011922014-01-10T11:16:41.175-05:002014-01-10T11:16:41.175-05:00Great collaboration!Great collaboration!Anonymoushttps://www.blogger.com/profile/05594611727147059236noreply@blogger.com
