Our company has begun development of a portable EEG system using the ADS1299.

Other Parts Discussed in Thread: ADS1299

We have purchased several of the evaluation systems and we would like to begin a discussion of issues regarding decisions we need to make for optimal acquisition and communication. To begin I understand that there may be source code available for communication between a TI DSP  and this chip. Can we download this?

    Robert,

    I'm moving your post to the correct forum. The Precision Data Converter group is more suited to answer your questions.

    Hey Robert,

    Yes you can download it here: www.ti.com/.../ads1299eegfe-pdk

    One disclaimer, though: this code was written for the EVM specifically. It uses the styx application server to create file system for firmware to interface with the device. It might be difficult to parse through all of this code. In addition, it will scarcely be helpful for any other processor besides the one for which the code compiles.

    Communication with the ADS1299 is relatively straightforward and occurs via an SPI-compatible interface like you may be familiar with in other projects. The specifications for the interface can be found in the datasheet. I'd be happy to answer any questions you have about that interface.

    Regards,
    Brian Pisani
