IWRL6432BOOST: Send Config file/Parameter via SPI

IWRL6432BOOST: Effect of SensorStop and Lowpowercfg

Tool/software:

Hello,

In order to receive the raw data via SPI, it is advisable to maintain SensorStop 0 and disable LowpowerCfg.


This removes the essential function of the sensor, which is to manage energy. I want to use the Radar with as little energy as possible and therefore I think it would be better to enable Lowpowercfg. Can I activate this mode and still limit the number of frames? If not, there is another alternative solution.

Here's the document that gives the recommendations on SensorStop and Lowpowercfg, SPI Data Capture

    Hello.

    You can enable lowPowerCfg, but you will need to make sure that you send out all of your data prior to the device going into deep sleep.  The reason its cautioned to avoid low power is because in low power the device peripherals, including the SPI peripherals turn off, so you will want to get all your data out before this point.

    Sincerely,

    Santosh
