CC2650STK: CC2650STK + CC-DEVPACK-DEBUG

Part Number: CC2650STK

Hi All,

Customers are considering connecting two acceleration sensors to the outside of CC2650STK and evaluating it.

The acceleration sensor is 4-wire SPI I/F.

When CC2650STK + CC-DEVPACK-DEBUG is connected, is it take 2 channels of 4-wire SPI signal from the CC-DEVPACK-DEBUG's test points?

For example, four signals DP0 to DP3 (DIO_23, DIO_24, DIO_25, and DIO_27) and other four signals DP8 to DP11 (DIO_17, DIO_18, DIO_19, DIO_20) are set as the SPI function, Can I communicate with each acceleration sensor?

Is this Correct？

Best Regards,

Takashi

    Hi,

    The sensortag project only uses SPI0 for accessing its sensor. You can find the pin map in sensortag's board file. (C:\ti\simplelink\ble_sdk_2_02_01_18\src\boards\CC2650STK\CC2650STK.h)

    You can assign any IOs that's available to SPI1 and then to communicate with your add on sensors
