i want to see the sensor values in board terminal what should i do

You can try this after loading the mangoh software:

github.com

mangOH/mangOH/blob/master/apps/YellowSensor/components/sensors/imu/Component.cdef

//--------------------------------------------------------------------------------------------------
/**
 * Component definition file for the mangOH Red Inertial Measurement Unit (IMU)

cflags:
{
    -std=c99
}

provides:
{
    api:
    {
        $CURDIR/../../../interfaces/imu.api
        $CURDIR/../../../interfaces/temperature.api
    }
}

i have installed the imu app and it is runing but i can’t see the sensor values

jyijyi · September 22, 2023, 1:52pm

You cannot just install the app as there is driver in the mangoh software

Are you using mangoh yellow board?

nayanhn · September 22, 2023, 1:57pm

yes yellow board,

i have updated the firmare from mangoh board but driver i did’t know

jyijyi · September 22, 2023, 2:11pm

Did you install the image here?

nayanhn · September 22, 2023, 2:13pm

yes without octave spk file

jyijyi · September 22, 2023, 2:14pm

Did you find any value here?

like how i have the same in my file i have not changed anything
i have puted like below in my code

file:
{

if ${LEGATO_TARGET} = wp76xx
/sys/bus/i2c/devices/6-0068/iio:device0/in_accel_x_raw /driver/

}
}

I suggest you trying in console to “cat” the path first

nayanhn · September 22, 2023, 2:20pm

sir iam new to this board
but i could not understand what u r trying to say

can explore or give an example

jyijyi · September 22, 2023, 2:21pm

What did you see for “cat /sys/bus/i2c/devices/6-0068/iio:device0/in_accel_x_raw”?

nayanhn · September 25, 2023, 4:29am

sorry sir it was limit for me to message so i could’t other day

root@swi-mdm9x28-wp:~# cat /sys/bus/i2c/devices/6-0068/iio:device0/in_accel_x_ra

root@swi-mdm9x28-wp:~# cat /sys/bus/i2c/devices/6-0068/iio:device0/in_accel_x_ra
w
-1670

sir i am getting like this

jyijyi · September 25, 2023, 5:55am

then the driver of sensor are working fine

didn’t you just want to sensor’s value?

nayanhn · September 25, 2023, 5:56am

sir but temperature values it was showing are not correct wright

jyijyi · September 25, 2023, 5:59am

what do you see for the following?

/sys/bus/i2c/devices/6-0068/iio:device0/in_temp_scale 
/sys/bus/i2c/devices/6-0068/iio:device0/in_temp_offset

i am getting like this

can’t you extend the messeging times more for this forum

jyijyi · September 25, 2023, 6:45am

you can refer to imu.c, in line 160, it uses
*readingPtr = (*readingPtr + offset) * scaling / 1000;

hello sir

where i can get yocto compilation for mangoh yellow board ,wp7608,
how to build instructions and git repository link

thank you

jyijyi · September 30, 2023, 4:45am

which FW are you using for WP7608?
FW R16.1?
If yes, you can download the yocto source here:

https://source.sierrawireless.com/resources/airprime/software/wp76xx/wp76xx-firmware-release-16,-d-,1-components/#sthash.F2uJ6ii0.dpbs

Just extract it and type “make” to build the yocto image.
