hi everyone,

I look for mpu-9150 tutorial. (but I can't find anywhere).

are you help me?????? please ...

gyroscope have..
(pins: VCC, GND, SCL, SDA, EDA, ECL, ADO, INT).
and the name is mpu-9150 gy-9150

2

Apart from here?

3

these example have not the pins (EDA, ECL).

pins are different from my gyroscope. (one time I m burned my sensor infrared, and do not want that to happen to my gyroscope).

any idea?

4

this is my gyroscope

any help, please !!

I use the mpu 9150 as well.
You can find a nice code to use it here => https://github.com/Pansenti/MPU9150Lib
also: http://pansenti.wordpress.com/2013/03/26/pansentis-invensense-mpu-9150-software-for-arduino-is-now-on-github/

it works pretty well.

I need any circuit example too.

Can you help me?

It depends on your arduino board and on your sensor breakout board, but you should do something like this:

Arduino -- Sensor
5V -- Vcc
Gnd -- Gnd
SDA pin -- SDA
SCL pin -- SCL

For the SDA and SCL pin it depends on your arduino board (see here Wire - Arduino Reference)

Another thing you have to be CAREFUL of the voltage or your arduino board and sensor board. If your arduino voltage is 5V and your sensor only accepts 3.3V you could fry the sensor.

thanks (this is useful).

but .. can you tell me about (eda, ecl, ado, int)? (I have not found reference to this)

thanks again,

If you use Pansenti code you don't need these extra pins. Which code do you plan to use? Do you want to write your own?

Anyway, I am not too sure but I think the pin "INT" is only useful if you use interrupts in your code. EDA and ECL might be used to connect an additional pressure sensor and for ADO, I have got no idea.

understood ^^, I will use Pansenti.

thanks

The answers are in the datasheet http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Sensors/IMU/PS-MPU-9150A.pdf
page 20
ADO : I²C slave adress LSB
ES_DA (guess it's EDA on the breakout) : auxxiliary I²C master serial data
ES_CL (guess it's ECL on the breakout) : auxiliay I²C master serial clock
INT : interrupt digital output

and the details are a little further in the datasheet (p. 25..... )

I am using the same MPU 9150 module. I have read the value of AD0 pin. Can anyone please guide me how to extract raw data from MPU 9150. I am using Arduino UNO

The links of code mentioned above are no longer working.
