CC2674R10: Sensor Controller Capability

Lawrence Wong

Part Number: CC2674R10

Looking for guidance on the capability of the Sensor Controller for customer. 

They want to know if it can be configured on a periodic basis (say 2Hz).  A generic sequence can look like:

1. set/clear 2 GPIO pins

2. Write a few bytes of known/static data set over SPI to external device

3. Collect some data over SPI to memory for Main CPU to work on.

4. clear/set 2 GPIO pins

5. Wait and repeat above sequence

    Hi Lawrence,

    This sounds definitely possible:

    - The Sensor Controller can handle GPIOs

    - The Sensor Controller can handle SPI operations (both Tx and Rx)

    Assuming the data to collect (point 3) remains fairly limited, the memory offered by the Sensor Controller should be sufficient.

    Similarly, unless the SPI transfers are taking more than 500 ms, I am confident you can get the periodic execution wanted.

    Best regards,
