BME280 with NRF5340 display (T,P,H) problem

[Rihab]

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

Hello,

Thank you for the detailed description.

I found a thing or two that might be causing this. I am trying to reproduce the error and will get back to you shortly.

Hello Hakon,
i figured out the problem of flashing 
it's related to the nrfjprog which was causing a problem
and i succeeded to flash my NRF5340 and communicate with the NRF connect 
but now i'm having a little problem simpler then all of this 
i m trying to communicate with BME280 but everytime i'm getting 

*** Booting Zephyr OS build v2.4.99-ncs2 ***
No device "BME280" found; did initialization fail?

which is related to the main.c on the bme280 related to zephyr projects

}

so the ponter is blocked on Null 
 do you have a suggestion on how to fix it 
or do you recommend something to replace it with 

[Rihab]

in fact the error that i posted is related to this file and exactly to the bloc in grey on nvic.h file

"  C:/Users/rzaafouri/ncs/v1.5.1/zephyr/include/arch/arm/aarch32/cortex_m/nvic.h:15:44: error: pasting ")" and "_P_arm_num_irq_priority_bits" does not give a valid preprocessing token  "

i'm getting these couple of errors do you know if there's a link between them 
because my error is certainly a processing error 
can you help with this please

knowing that i just tried to open another project from a different directory then the BME280 project 
it went all on collapse ! 

can you please help me please 
 i really need help 

[Rihab]

Hello Helsing,
the error related to the devicetree could be resolved by putting all the project substances in the same version of SDK
the building is breakable if the main and the nrf**.overlay are not on the same version 
thank you for your help 

[Rihab]

Hello Helsing,
thank you very much 
i'm recently having an issue with the display of the values of the BME280
well it's displaying this error when the sensor is connected to the Kit

and it's displaying this error with the other address when it's not connected

Knowing that : 

0x0BAD0001 means "Internal Error" in the I2C driver.

0x0BAE0001 means "Address not acknowledged" in the I2C driver.
and doubting that the issue is hardware that leads me to believe that the issue may be with how the sensor is wired to the board, or setup in some way, causing an error in the driver.


for me i did the wiring like this 

P1.02 to SDI
P1.03 to SCK
GND to SDO
GND to GND
Vin 3-5v to VIN

is there a pre-config to do or some settings to fix before running the sensor ?

can you please help me with the wiring 
knowing that you already tried the sensor, how did it go with you please ?
can you help me please 
i would be very grateful

[Rihab]

the final answer for the display of this problem was related to the voltage 
try to double check with a voltage meter that the input voltage is 3V
Find a pin labeled "VDD", and try that if you measure it to be 3.3V.
in this case the needed voltage is 3.3V
make sure your pins wiring is good
