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.

HI,

shall I know how to modify SDK_14 to SDK_15.2.

Is there any tutorial for that. Please share..

[Jørgen Holmefjord]

There is a Migration guide in SDK 15.0.0 Getting Started section. Migration from 15.0.0 to 15.2.0 should be simpler as it is not a major SDK version update.

Migration from 15.0.0 to 15.2.0

But if we convert 14.2 sdk to 15.2 sdk. is might be same or its different as SDK version update

[Jørgen Holmefjord]

There should not be API changes from 15.0.0 to 15.2.0, but there could be additional features, bug fixes, etc. Follow the migration guide for SDK 15.0.0 and you should be well on your way.

HI, I have installed the project in SDK14.2 as instructed.  The project compiled and download with no error on the nrf52DK board.   The MPU9255  is connected by i2C with SCL to pin P0.27, SDA to pin P026.  Those pin number have been define in  the nrf_drv_mpu_twi.c file. The MPU9255 is define in the Preprocessor definitions.  

Whe I run the program, I have the following error reported on the USB port: 

<info> app: [2J[;H
<warning> nrf_sdh_ble: RAM starts at 0x200020E0, can be adjusted to 0x20002A68.
<warning> nrf_sdh_ble: RAM size can be adjusted to 0xD598.
<error> nrf_sdh_ble: sd_ble_enable() returned NRF_ERROR_NO_MEM.
<error> app: Error 0x0004 (4) at line 566 in file: /Users/slareau/nrf52 development/nRF5_SDK_14.2.0_17b948a/examples/nrf5-mpu-examples/nrf5-ble-mpu-simple/main.c

Line 564 to 566 in main.c are :

    // Enable BLE stack.
    err_code = nrf_sdh_ble_enable(&ram_start);
    APP_ERROR_CHECK(err_code);

Could someone help me ?
