Other Parts Discussed in Thread: CC2540, ADS1298

Hi，

  1.I want to only use the ADS1298ecg-fe without the mmb0.

 2.I want to sent the data acquired from the  ADS1298ecg-fe to PC by the cc2540.This method is OK?

 3. How do the PINs  connect to the cc2540?

 4.Which pins is about spi in cc2540?

    Hello user4215304,

    There are a couple things I would consider before using a different host on a different board with the ADS1298ECG-FE. First, the MMB0 board supplies power to the ADS1298. You will either have to keep the MMB0 plugged in for power or find another way to provide a valid supply to the ADS1298. In addition, you will have to maintain a common ground and the same logic levels for the communication between the CC2540 and the ADS1298.

    As for the ability to use the CC2540 to communicate with the ADS1298, there's nothing to suggest that it isn't possible since the CC2540 has SPI communication capabilities. I'm not sure which pins are the SPI pins on that processor, but I'd recommend looking at its datasheet: www.ti.com/.../cc2540.pdf

    The SCL and SDA pins are Serial Clock Line and Serial Data line for the I2C interface for that particular part.

    Regards,
