Trying to use nordic_nrf_temp in Zephyr open thread

[riedlse]

I have the driver setup like all of the other sensor drivers I'm using, but I can't seem to find a device tree or Kconfig 

This should be enabled by the CONFIG_SOC_NRF52840_QIAA=y enabling config HAS_HW_NRF_TEMP

Do I need something in the board overlay, dts or ????

#define TEMP_NODE DT_INST(0, nordic_nrf_temp)

#if DT_NODE_HAS_STATUS(TEMP_NODE, okay)

#define TEMP_LABEL DT_LABEL(TEMP_NODE)

#else

#error Your devicetree has no enabled nodes with compatible "nordic,nordic_nrf_temp"

#define TEMP_LABEL "<none>"

#endif

    const struct device *chip = device_get_binding(TEMP_LABEL);

    if (chip == NULL) {

        printk("No device Nordic nrf temp found; did initialization fail?\n");

    } else {

        printk("Found device Nordic nrf temp Thermistor\n");

        fchip = true;

    }

      if (fchip) {

            ret = sensor_sample_fetch(chip);

            if (ret < 0) {

                printk("Chip Die temp Fetch error %d\n", ret);

            } else {

                struct sensor_value temp;

                sensor_channel_get(chip, SENSOR_CHAN_DIE_TEMP, &temp);

                printf("Chip die Temperature: %.2f C\n", sensor_value_to_double(&temp));

            }

        }

Wanted to add something, with the latest version of nrf connect and zephyr I get a warning that mpls and nrf5 temp are incompatible. The good news is the mpls is MUCH easier to use, no sensor or driver work needed....

#include "mpsl_temp.h"

        int32_t dt = mpsl_temperature_get();

        double ddt = dt/4.0;

        printf("MPSL Chip die Temperature: %.2f C\n", ddt);

This is correct, TEMP is owned by MPSL and you need to use the mpsl_ API to get the temperature. TEMP is used for calibration of temperature-dependent resources, like the LFCLK.
