Nordic api equivalent in nRF_Connect_SDK

[Bhumika]

Hi,

I had my application running on nRF_SDK_For_Thread_and_Zigbee.

I have been following SDK APIs directly in my code to calculate certain parameters:

1.  nrf_temp_read()

2.  NRF_DRV_SAADC_DEFAULT_CHANNEL_CONFIG_SE(NRF_SAADC_INPUT_VDD) (for calculating battery life- analog peripheral example)

3. nrf_mem_init()

4. nrf_cal_get_epoch_time()

Could you please help me in finding their equivalent APIs in nRF_Connect_SDK?

Hi,

1. If you set CONFIG_TEMP_NRF5 in your prj.conf file, you can read the temperature using the sensor API, as shown in the BLE HTS sample. The TEMP HAL is also available in nRF Connect SDK through nrfx.
2. Have a look at the Battery Voltage Measurement sample in Zephyr.
3. I'm not sure what you have used this for, but you can have a look at the Memory Management functions in Zephyr.
4. I'm not sure what this function does, I can't find it in the nrf-calendar example. Is this something you implemented yourself? Anyways, have a look at Time Utilities in Zephyr.

Best regards,
Jørgen

Hi,

You can reference this unofficial ADC example. You should be able to pass NRF_SAADC_INPUT_VDD to the input_positive configuration parameter.

Best regards,

In this one, 

I am getting the following error :

 error: 'NRF_SAADC_NS' undeclared (first use in this function); did you mean 'NRF_SAADC_H_'?
   86 |     NRF_SAADC_NS->TASKS_CALIBRATEOFFSET = 1;
      |     ^~~~~~~~~~~~
      |     NRF_SAADC_H_

Also, can you explain the prj.conf of this sample, which config is used for what purpose?
