mpu6050 on Nrf51822

[nick]

Hello

Is there any example or tutorial on how to use the mpu6050 library? I just started to program the nrf51822 and hope to find some helpful clues to get me going.

Any suggestion would be appreciated.

Update: I got the mpu-6050 working on keil, but without the mentioned examples. I did found some example on a chinese website. With some help of google translate i got to tweak it a little. For someone who is just a beginner most examples look difficult so i am already happy i got it working. And i can work forward from that base. For everyone who likes to use this very simple example. Here is my project; NRF51-MPU6050.rar

Hi,

I am using a 3rd Rev NRF51822 (AA) with MPU9250. Does the 9255 example work with it. I tried using the simple mpu example with SDK11.0.0 but could not see any values on the terminal. It was just updating the sampling number.

The example seems to work on my nRF51 DK and MPU9255. I have some random troubles with the serial terminal though. I use Tera Term and sometimes I have to close and reopen it again to see the data. Did you remember to define the correct pins and the correct MPU in Targ Options?

I compiled it using Segger Studio, have used the correct pins and MPU on the preprocessor definitions. I used the JLinkRTTClient to see the result on the terminal. This is the output I got:

Looks like JLinkRTTClient doesn't know how to format the data properly. I have no experience with Segger Studio. What function do you use to print to the JLinkRTTClient?

You should see something like:
