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

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

Rihab — Wed, 11 Aug 2021 09:11:42 GMT

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

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

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

Hello Helsing,
i succeeded to resolve the error of processing
i reinstalled the SDK and the toolchain manager
i reconfigured my environment
and then i got to deal with the device tree issue so i putted the pin config aka this one

&i2c1 {
    compatible = "nordic,nrf-twim";
 status = "okay";
 sda-pin = < 34 >;
 scl-pin = < 35 >;
    clock-frequency = <100000>;
 bme280@76 {
  compatible = "bosch,bme280";
  reg = <0x76>;
  label = "BME280";
 };
};
&uart1 {
    status = "disabled";
};

on the overlay file "nrf5340dk_nrf5340_cpuapp.overlay"

and the build was successful

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

Rihab — Fri, 06 Aug 2021 13:02:28 GMT

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

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

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

Rihab — Fri, 06 Aug 2021 12:51:03 GMT

yes when my config was right i used to have the line just like the image you posted
and speaking about my overlay file it looks just like this

&i2c1 {
    compatible = "nordic,nrf-twim";
	status = "okay";
	sda-pin = < 34 >;
	scl-pin = < 35 >;
    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";
};

the stars i putted the when i posted my question to make it easy for you to stop the right line ( i said "the line 698 in the nrf5340dk_nrf5340_cpuapp.dts.pre.tmp is the line 8 below and so on")

so my overlay was good from the beginning

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

helsing — Fri, 06 Aug 2021 12:44:07 GMT

I have a feeling that your overlay file is not working properly.

Also, I just noticed that four rows with '*' in the file nrf5340dk_nrf5340_cpuapp.dts.pre.tmp in your build folder.

Is this something you added? Or do you perhaps have some remains of old comments in your overlay file? Perhaps cleaning up the overlay file will work?

In your text editor, are you able to see these lines grayed out? If your device tree(and configs) is set up properly you should see something like the image below (This method might not be 100% accurate, though it could help indicate when something is wrong.)

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

Rihab — Fri, 06 Aug 2021 12:38:06 GMT

i just tried to create another project but from another directory this time
i think i broke something in the processing operation
but the thing is that in my project BME280

the DT_NODE_HAS_STATUS function became grey
and the other one appeared
so i think even by correcting this error
i will get the classic error of "devicetree has no enabled nodes"

i don't know what to do actually, i tried alot of methods but the error doesn't go

do you recommend some team members that can help me
i'm really stuck and it's getting complicated

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

When did this start appearing? What do you do in order for this to appear. Do you remember any recent changes you made?

I am not familiar with this, though it looks like something that would need to be fixed. I suggest you create a new ticket, and someone else from our team will be assigned to the task.

Hi Rihab,

What does your config file currently look like? Have you tried using these four configs at the same time?

CONFIG_SENSOR=y

CONFIG_BME280=y

CONFIG_I2C=y

CONFIG_I2C_1=y

When using these configs, I can read this in the terminal:

*** Booting Zephyr OS build v2.4.99-ncs2 ***

Found device "BME280"

This happens even though I do not have any sensor connected at the moment.

Thank you for the updates.

Do you have any tools available for checking whether there is any activity on the I²C lines? Do you see anything now?

Anyways, here is something to try. Try adding the following to prj.conf:

I see others adding this line too, though I have not yet checked whether it is necessary or not:

I see that the error occurs after the overlay file, nrf5340dk_nrf5340_cpuapp.overlay, has been processed(C:/Users/rzaafouri/ncs/v1.5.1/nrf/samples/sensor/bme280/boards/nrf5340dk_nrf5340_cpuapp.overlay).

"Error: nrf5340dk_nrf5340_cpuapp.dts.pre.tmp:698.16-17 syntax error"

If you check the build folder and open the file nrf5340dk_nrf5340_cpuapp.dts.pre.tmp and scroll down to line 698 you should find the syntax error causing this message.

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

Could you please try the following for your I2C pins in the overlay?

sda-pin = < 34 >; //(32+2)

scl-pin = < 35 >; //(32+3)

Let me know how it goes, as I have not yet tested this myself.

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
