RTOS/CC2650MODA: UART Power Management for CC2650MODA using Sensor Controller Studio

Part Number: CC2650MODA
Other Parts Discussed in Thread: CC2650

Tool/software: TI-RTOS

Hi, 

I am currently testing UART with CC2650MODA booster pack and have a question regarding power management. 

I am trying to use sensor controller studio to save power and put the main mcu to sleep whenever possible. 

However, even though I use sensor controller studio for uart, it seems like Ti-RTOS code needs to run in the main mcu. 

How is this saving power compared to just using TI-RTOS for uart? 

Sincerely, 

Eun Sun

    Hi Eun Sun,

    I am not sure what TI-RTOS code you are referring to. The Sensor Controller can operate 100% autonomously without any interaction from the main MCU. Eventually you will typically wake up the main MCU to fetch and do something with the data from the Sensor Controller, but how and when you do that is completely up to your application.

    Regards,
    Fredrik

    Hi Fredrik,
    There is uartecho example in CCS under TI-RTOS CC2650 folder, which solely uses TI-RTOS.
    On the other hand, if I generate uart example on sensor controller studio, it has a document that explains about uartemulator() function. And when I generate driver, it give me ccs code that generate task with semaphore.
    Wouldn't this code in ccs also run ti-rtos?
