ADS1298ECGFE-PDK interface with Development board of Microcontroller

Other Parts Discussed in Thread: ADS1298, ADS1298ECGFE-PDK

Hello,

I am looking into purchasing the ADS1298ECGFE-PDK. I want to use this in order to interface directly with a microcontroller I have purchased, that is currently on an Explorer 16 development board. Would it be possible for the ADS1298ECGFE-PDK to interface with this board through wire connections (i.e. jumper wires), or would additional hardware be required? In regards to this connection, are there are any other boards TI offers designed for interfacing the ADS1298 with this particular development board?  I have posted a link to the Explorer 16 development board below.

Thanks,

    Hey Noel,

    It is probably possible to wire over the SPI connections and power the ADS1298 board, but given that we market that product as an evaluation module, we can't provide technical support as if it were a development platform. To answer your second question, there are no such special boards that TI offers to interface the ADS1298 to another platform.

    Hi Brian,

    So the ADS1298ECGFE-PDK is capable of transmitting data via SPI? I just want to make sure about this, because it is essential for my project.

    Thanks,

    Hey Noel,

    Yes it should work. You'll have to check the schematic and the ADS1298 datasheet to figure out how to get everything to work.

    Hi Brian,

    Thank you for the response! I have one last question. I understand that purchasing the ADS1298ECGFE-PDK also includes a board that has a Texas instruments DSP processor. Is this required for complete functionality, or would I be able to only interface with the board that has the ADS1298 soldered onto it? My goal is to have the ADS1298 connect data and then send it to the microcontroller.

    Thanks,
    Noel Teku

    Hey Noel,

    Connecting only to the ADS1298 board is what I was referring to. You're not going to want the DSP connected since you will need your micro to control the bus. The DSP board provides power to the ADS1298 board, though, so you'll have to find a way to do that with your new setup.

    Hi Brian,

    Thank you so much. Is there a way of purchasing the ADS1298ECGFE-PDK without the DSP board, or does it just come by default? Also, I understand from watching a video about the ADS1298ECGFE-PDK that it does comes with an external 6V power supply. Do you know of any ports on the board with the ads1298 that are soldered on for us to feed in voltage without using the power supply?

    Thanks,

    Hey Noel,

    Unfortunately it only ships with the MMB0 board. In addition, we just recently changes our policy about wall wart power supplies to better comply with international regulations. We no longer ship a ac adapter with the EVM. Is the video you watched from TI? If so please send me the link. To answer your last question, looking at the schematic, it seems like the positive 5V from the MMB0 which powers everything on that board comes in at pin 10 on J4 but can also be accessed from TP 7.

    Hi Brian,

    Again, thank you so much for all of your help. The video is from TI, and I have posted the link below.
