B4R Question type as return ?

[vali khandangoll]

Hi
I use a library with name TinyMPU6050 that attached below.
fow show the gyroscop x or y or z angle must use mpu6050.GetAngX command

this command format is mpu6050.GetAngX(ang X as:: return) as float.
please help me with an example about ang X as:: return.
or an simple B4R example for this library.

thanks.

You cannot access a C struct directly. You will need to create a wrapper or access the fields with inline C.

So please help me and write a source code that used this tiny mpu library.
you can download that from this url.

TinyMPU6050

Tiny implementation for MPU6050 focusing on performance and accuracy

or another code with any library you want

thanks

Hi Erel.
I am waiting to your guidance.
an example source code used by this library can solve my problem.

my quadqupter project was stoped.

thanks

float GetAngX () { return angX; };

It returns float. Not a a type.

please look at this pic.

How did you create the XML?

It might work if you change:
float GetAccX () { return accX; };

To:
float GetAccX ()
{ return accX; };

i created a wrapper for TinyMPU6050, do you want to test it and to check if it can help you ?

testTinyMPU6050 is script used to test this library, and it is an example to use it

files deleted => please to use files below

hi
I download and tested your program and library.
It seems that the values it shows are not correct.

Have you tried it yourself?
I already said above that I desperately need this program.
I would be very grateful if you could solve this issue for me.

بسیار بسیار متشکرم

no i didn't test this library with MPU6050 because i don't have one available , but i will do soon.

after, i think your wiring is not correct, because with this library, you have aleatory values when MPU6050 is not connected. (we have no error return in case of error)

Please to check your I2C wiring with B4R script below: it will detect MPU6050 at address 0x68 if it is correct

=> please to use files below

after a test of MPU6050 , please to find a new version of I2C_scanner and a new version of rTinyMPU6050.

in my case, with I2C_scanner i can confurm MPU6050 availability at address 0x68 and after test with TinyMPU6050 library is OK

you can try with this other library : https://github.com/emanbuc/ESP8266_MPU6050

this one check MPU6050 at start

in my case, this one is working also
