INA219 Sensor wrong data display

[Rihab]

Hello Community,

I'm using the current sensor INA219 with NRF5340dk.
Communication is through i²c protocol and using nrf SDK v1.7.0 .
I'm trying to get the data output (Voltage, Current, Power).
i worked on the sample linked on Zephyr Lib. the problem is that i'm always getting the same output which i liked below

the wiring of the sensor is like below :

Vin->VDD nrf
GND->GND
SCL->P0.26
SDA->P0.25

I'm always getting the current and power to Null values and both voltage values don't change no matter what !
do i need to change the calibration values or do i need to do something else ?
i don't get what's wrong with the data output so i need your help please
can you help me get the right values and get the data displayed out from the sensor correctly, please

Kindly,
Many thanks

Try removing CONFIG_STDOUT_CONSOLE=y from prj.conf.

If that doesn't fix it replace CONFIG_CBPRINTF_FP_SUPPORT=y with CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y.

i tried removing CONFIG_STDOUT_CONSOLE=y from prj.conf
it didn't fix the problem 
i replaced CONFIG_CBPRINTF_FP_SUPPORT=y with CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y with CONFIG_STDOUT_CONSOLE=y being removed
it didn't work neither 
there's no output message on the the terminal emulator

i deleted the build file between the two changes 
to eliminate the probability of error 

i even added some logs before and after this part 

	if (!device_is_ready(ina)) {
		printf("Device %s is not ready.\n", ina->name);
		return;
	}

but none of these logs was displayed

Ok, just tested it myself. You can undo the changes to the prj.conf I suggested in my last reply.

What terminal are you using? The one in SES only works for RTT as far as I know, you want something like PuTTY

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_testing.html

I get output on the COM port when I test the sample.

when i was on the V1.7.0 i used to visualize data on the terminal of SES.
infact the snipped output photo was from there ( but the data wasn't correctly displayed).
but for now i just downloaded Putty to be able to visualize data.
but i'm not really familiar with it.
can you give helpful links please to be able to use it and visualize data through it.
and how can i link it to SES built ?
