could OpenBCI support Texas Instruments ADS1299EEGFE-PDK ?
Texas Instruments is partner of OpenBCI and has a EEG board which is affordable, but it is not very often used. It has been tested for it s accuracy and compared to EEG systems which are more expensive:

The ADS1299 Performance Demonstration Kit is low-cost, it has an easy-to-use evaluation software for Microsoft Windows, and it can be interfaced to MATLAB, and therefore to EEGLAB. OpenBCI has an excellent support forum, the community of low cost EEG devices is small and should cooperate. OpenBCI support for the ADS1299EEGFE-PDK would be desirable.
Comments
The TI eval kit was examined for specifications in the design of the original Cyton. But the current Cyton has many features that the TI kit lacks:

Thank you William. But for someone who can do without these features, the Texas Instruments ADS1299EEGFE-PDK evaluation board is the most affordable solution. But I miss a community of users who is sharing their experience with this board. The OpenBCI community is the largest community for these kind of devices, and should support this board.
Do you understand that open-source hardware projects, are only supported by the revenues from hardware products sold? There are no other income sources. Open source hardware is very different than open source software. As there are large and significant overhead costs for hardware projects.
The other aspect about the TI kit that makes it impossible, is that the usb interface is proprietary (secret), only intended to talk to their custom Windows app. It is only designed for demonstration testing, as the documentation states. The doc also states multiple times that the kit is NOT to be used on human subjects.
The Texas Instruments support answered regarding the question of ADS1299 EVM thirt party software in the following way:
“The ADS1299 EVM was primarily designed to operate with the TI based ADS1299 GUI.
It may be possible to interface to 3rd party software like Matlab but you will need to develop your own firmware to control the EVM interface via Matlab.
TI will not be able to support you with your firmware / software development.
As you have pointed out, there are multiple researchers who have done this integration on their own effort.”
In the papers I mentioned is written that it is possible to interface the TI demo board software to Matlab.
The ADS1299 EVM is not sold for medical use. The two papers I mentioned compared the accuracy of the ADS1299 EVM with a medical grade device, and came to the conclusion, that the ADS1299 EVM can be used instead of the medical grade device as far as accuracy is concerned.
Feel free to fork the GUI and Brainflow, if you want to interface to this demo kit. The interface usb protocol is proprietary and not shared by TI. TI explicitly states that the kit is not safe to connect to humans. It's only a test system.
I don't believe you need to make any more requests for support of this kit. As we've already gone back and forth numerous times on this.
