ADS1278-EP: ADS1278 SPI interface with TMS320F28335

Part Number: ADS1278-EP
Other Parts Discussed in Thread: TMS320F28335, ADS1278, C2000WARE

Hi,

We need to interface ADS1278 with TMS320F28335 via SPI. Can you suggest us whether this ADC SPI interface is compatible with normal SPI device driver module which is provided by Texas in example code.

Is it compatible with McBSP SPI interface  ?

Also the sampling rate is mentioned as 128-kSPS, from  datasheet I am assuming that 128-kSPS for each individual channel simultaneously. Is it correct understanding?

  • Sachin,

    I will research this and get back to you with information to help interface the ADS1278 to the F28335.

    I will get the person responsible for the ADS1278 to comment on the understanding of the sample rates as well.

    Regards,

    Wade

  • Sachin,

    I apologize for the delay.

    We do not offer example code for specific devices.

    However, there is some sample SPI code for the C2000 devices that can be use a an example.

    These are located in the C2000ware:

    I tried to find a TI reference design using the C2000 and and ADS1278 and unfortunately I did not find one.

    I was able to confirm that all the ADS1278 channels are simultaneous.

    Regards,

    Wade
