NCS how to close SPI, I2C, ADC,NVS

[yoyou]

Hello,

nRF5340, NCS1.9.99, VSCode

  

adc_dev_ = device_get_binding("ADC_0");

i2c_dev = device_get_binding("I2C_0");

spi_dev = device_get_binding("SPI_3");

rc = nvs_init(&fs, flash_dev->name);

      

how to close those devices before enter sleep mode?

   

Best regards

Hello,

You should be able to use the Power Management API for that.
Add add CONFIG_PM_DEVICE=y to your prj.conf and then you can use the following function to suspend and resume the devices.

pm_device_action_run(i2c_dev, PM_DEVICE_ACTION_SUSPEND);

pm_device_action_run(i2c_dev, PM_DEVICE_ACTION_RESUME);

You can read more about it here

And here is the API description:
