Hello everybody,
I'm having a problem to display the temperature, pressure and humidity.
i followed this tutorial on a NRF5340 https://devzone.nordicsemi.com/nordic/b/archives/posts/nrf-connect-sdk-tutorial---part-3-temporary
in my case i'm using SES V5.34a avec NRF Connect v3.7.0 with NRF SDK V1.5.1
i'm working with BME280 adafruit! (3-5)voltage
below is my nrf5340dk_nrf5340_cpuapp.overlay
as the scl pin is on P1.03 and the sda is on P1.02
&i2c1 {
compatible = "nordic,nrf-twim";
status = "okay";
sda-pin = < 34-32 >;
scl-pin = < 34-31 >;
clock-frequency = <100000>;
/* The I2C address could be one of two, here 0x76 is assumed */
bme280@76 {
compatible = "bosch,bme280";
reg = <0x76>;
label = "BME280";
};
};
&uart1 {
status = "disabled";
};
and my prj.conf is below
CONFIG_SENSOR=y CONFIG_BME280=y CONFIG_I2C_1=y
and for the main.c i useed the code linked on the nfr/samples/sensor/bme280

}
}
my build is going well on SES and it's successful but when i try west flash from bash or Cmd prompt i'm always getting errors

could you please help me solve my problem and be able to get returned values of my sensor bme280
or if you see that i have something wrong with my configuration, don't hesitate to tell .
i will really appreciate your help and contribution
thank you in advance
