Hi there, I am begineer for nrf51822 and I want to interface MPU6050 WITH nrf51822 so can somebody provide me the tutorial with full detail.i want to read just raw values of mpu6050. How to use Neil I'd? How to write a program for nrf51822?
Great help appreciated!!!

Hello, Abhijeet kapse.
I want to interface MPU6050 WITH nrf51822 so can somebody provide me the tutorial with full detail.
Well, I think it will be hard to help you to the fullest.
especially when you say
How to write a program for nrf51822? I want to interface MPU6050 WITH nrf51822
I hope you have Keil MDK or Eclipse installed on your computer.
And actually, there are great sources to learn.
Let's have a compromise; after you study these, create detailed questions and post them on the devzone.
However, to prevent creating duplicated questions such as, "nrf52832 ble transfer data continuously"
search some questions which might help you, please.
// In details
Since you have mentioned about
I want to interface MPU6050 WITH nrf51822
you should take a look at I2C, also called as TWI.
As you see the Nordic's SDK, the TWI example is provided. Use this example to understand TWI.
Unfortunately, in the readme page, it says that
Not tested on PCA10036 and MPU60x0
However, the MPU series is quite similar to others. So this is not a big issue.
You have to look at the register map of MPU6050.
Your goal is this; create a firmware that can read/write MPU6050's register.
The aforementioned GitHub link will provide a great help.
Also, please keep in mind that
The examples are not extensively tested and only meant as simple explanations and for inspiration. NO WARRANTY of ANY KIND is provided.
// In short,
Study about TWI (I2C) and try Nordic's TWI example ->
Read about the register map of MPU6050 ->
nrf51822 can read/write MPU's register with TWI, so start with reading the value from the WHO_AM_I register ->
configure registers using TWI, such as CLKSEL, FIFO_EN, more. Use the GitHub link to speed things up.
-Best Regards
