Hi,
I am trying to program the internal temperature of the nrf52832 development kit, I have this code so far it builds and when I flash it on the board; I get a message that the temp driver cannot be found. Can someone please help me with this issue?
#include <zephyr/kernel.h>
#include <zephyr/device.h>
#include <zephyr/devicetree.h>
#include <zephyr/drivers/gpio.h>
#include <zephyr/drivers/sensor.h>
#include <zephyr/drivers/i2c.h> /* STEP 3 - Include the header file of the I2C API */
#include <zephyr/sys/printk.h> /* STEP 4.1 - Include the header file of printk() */
/* 1000 msec = 1 sec */
#define SLEEP_TIME_MS 1000
void main(void)
{
struct device *temp_dev;
int ret;
temp_dev = device_get_binding("TEMP_0");
if (!temp_dev) {
printk("Didn't find the temp driver!\n");
return;
}
while (1) {
struct sensor_value val;
ret = sensor_sample_fetch(temp_dev);
if (ret) {
printk("Failed to sample temp sensor!\n");
return;
}
ret = sensor_channel_get(temp_dev, SENSOR_CHAN_DIE_TEMP, &val);
if (ret) {
printk("failed to get temp sensor data!\n");
return;
}
printk("Temp %d.%d\n", val.val1, val.val2);
k_msleep(SLEEP_TIME_MS);
}
}
Thanks in advance
