Original question:

CC2630: SPI Communication in Senosr controller

RTOS/CC2650: SPI Communication in Sensor controller

Part Number: CC2650

Tool/software: TI-RTOS

Hello,

At present I am using SPI communication for reading sensor data in  callback mode.The data rate is 19bytes in 4ms at 2MHz speed.

Is callback mode same as using sensor controller engine for SPI communication?

If not, will there be any power saving from callback mode to sensor controller engine?

Regards,

Jayant

    Hi Jayant,

    Using SPI in callback mode is not the same as using the Sensor Controller. It could be better considered as an "interrupt driven" way of using the driver where you do not have to poll/wait for a flag to know when the operation is done but instead get a callback.

    Depending on your application and what you do in addition to the SPI communication, you could very well lower the power consumption by moving this into the sensor controller. Basically, if you can lower the time the TI-RTOS (CM3) has to be active, you can potentially save power.
