MPU6050 with NRF52832 in segger

[Sunil vignesh]

Hi,

I am working on MPU-6050 sensor.

I have downloaded the NRF5-MPU-EXAMPLE  from this link

in that there is no SES file.

How to create a SES file to work this code in segger..

[Jørgen Holmefjord]

Hi,

I would recommend that you copy a SES project from another example in the same SDK version and modify this with the paths and source files required for the MPU examples. This video tutorial should show you how to add files into the SES project.

For instance, if you want to use nrf5-ble-mpu-data-ready-interrupts example on a PCA10040 board, you should copy the ses folder from examples\ble_peripheral\ble_app_uart\pca10040\s132\ into examples\nrf5-mpu-examples\nrf5-ble-mpu-data-ready-interrupts\pca10040\s132\ and then add the required MPU library files.

Best regards,
Jørgen

You need to define the symbols (in project preprocessor symbold), configuring what device you are using. This is specified in the "How to use" section of the GitHub repository page.

while in a code itself we need to select MPU-6050..? and TWI..?

[Jørgen Holmefjord]

You set it in the preprocessor symbols.

• Left click Project in the project file browser and selec  Options.
• Select Common from the dropdown menu at the top left corner.
• Click on Preprocessor under Code on left side.
• Double click Preprocessor Definitions.
• Add the flags as described on Github. In your case you should add MPU60x0 and MPU_USES_TWI.

Hi,

Thank you

i did that one.

The sdk_config.h file must be the BLE UART sdk file or

MPU_EXAMPLE\nrf5-ble-mpu-simple\pca10040\s132\config sdk_config.h

which one we need to use?

[Sunil vignesh]

HI,

I got one error it show sensorsim.h : No such directory

and  app_mpu.h : No such directory.

[Jørgen Holmefjord]

Means you have not included the paths to the header files in the project include paths. How to do that is described in the video tutorials I linked you. The MPU project you are using is not based on ble_app_uart, but on ble_app_template. The ble_app_uart example does not include all header file paths that is used by ble_app_template. With that said, it does not look like the example use sensorsim, and you can remove the inclusion of the header file from main.

Hi,

I command the sensorsim.h header file..

but it shows app_mpu.h error.but i added the header file

[Jørgen Holmefjord]

You have not included the path to the header file in the project settings.

• Left click Project in the project file browser and select Options.
• Select Common from the dropdown menu at the top left corner.
• Click on Preprocessor under Code on left side.
• Double click User Include Directories.
• Add the following path to the end of the list: '..\..\..\..\..\nrf5-mpu-examples'

[Sunil vignesh]

Hi,

Even though it won't work same error app_mpu.h : No such file or directory

[Sunil vignesh]

is this the file path in the drive or ??

I have used both forward slash and back slash  its doesn't change. error still occur
