After some research I can answer my question myself : to change ram start and size, you open «Project options», got to «linker» and to «Sertion placement macros», RAM start and size are the last values. See also : https://www.youtube.com/watch?v=uP8RYgYGRvI&hd=1&feature=youtu.be&t=254

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 ?

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.

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

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Tue, 23 Oct 2018 12:24:38 GMT

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.

HI,

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

Is there any tutorial for that. Please share..

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Tue, 23 Oct 2018 08:04:20 GMT

No, I'm not aware of any such code available. We provide basic examples of how to use the peripherals of our ICs. The customers need to modify these themselves to work with desired sensors. We cannot provide complete libraries for every available sensors that customers want to use.

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Tue, 23 Oct 2018 08:02:06 GMT

Yes, you need to change the path to the log directory in preprocessor include paths to the correct path in SDK 15.2.0. Note that the example is not written for SDK 15.2.0 and there might be many API changes between the major SDK versions.

Hi,

IS there any library that suits for BMI160 bosch accelerometer gyroscope sensor

any code related to SDK_15.2

HI Jorgen,

Thanks a lot for the project.

as you said i replace the directory and i build

i got 3 errors

F:\nRF52 SDK files\nRF5_SDK_15.2.0_9412b96\nRF5_SDK_15.2.0_9412b96\components\libraries\experimental_log\src\nrf_log_backend_rtt.c: No such file or directory

and i have seen in the preprocessor that

../../../../../../components/libraries/experimental_log

../../../../../../components/libraries/experimental_log/src

../../../../../../components/libraries/experimental_memobj

../../../../../../components/libraries/experimental_section_vars

while in my directory there no such experimental_log folder

but there is only log/src/ (in that those files are available)

shall i change the preprocessor file or else i need to create the experimental_log folder..

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Mon, 22 Oct 2018 09:06:59 GMT

You get these errors because you try to run the example in SDK 15.2.0. The Git repository say the examples have been written and tested for SDK 14.2.0, this is the version you have to use.

Please clone the mpu repository into examples directory in SDK v14.2.0. Then delete the entire nrf5-ble-mpu-simple directory, and extract the following: devzone.nordicsemi.com/.../nrf5_2D00_ble_2D00_mpu_2D00_simple.zip

I have created the project for you.

RE: MPU6050 with NRF52832 in segger

Sunil vignesh — Sun, 21 Oct 2018 15:35:37 GMT

HI,

As you said i have created the SES folder in the example path:

F:\nRF52 SDK files\nRF5_SDK_15.2.0_9412b96\nRF5_SDK_15.2.0_9412b96\examples\nrf5-mpu-examples\nrf5-ble-mpu-simple\pca10040\s132\SES

and copy the BLE_UART SES file into that and changed the name into nrf5-ble-mpu-simple_pca10040_s132 for EMPROJECT file and EMSESSION file and changed in the <open solution> in editor.

then I

1. remove the main.c file

2. added main.c file of nrf5-ble-mpu-simple_pca10040_s132, app_mpu.c,ble_mpu.c,nrf_drv_mpu_twi.c and nrf_drv_mpu_spi.c

3. in sdk_config.h file

#ifndef NRFX_TWI_ENABLED
#define NRFX_TWI_ENABLED 1
#endif
// <q> NRFX_TWI0_ENABLED  - Enable TWI0 instance
 

#ifndef NRFX_TWI0_ENABLED
#define NRFX_TWI0_ENABLED 1
#endif

#ifndef TWI_ENABLED
#define TWI_ENABLED 1
#endif

// <e> TWI0_ENABLED - Enable TWI0 instance
//==========================================================
#ifndef TWI0_ENABLED
#define TWI0_ENABLED 1
#endif

4. added User include directories and preprocessor definitions as

while Build the project i got 6 errors

Hi,

I have used BLE UART SES file and i add the main.c, app_mpu.c,ble_mpu.c and i use

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

but in

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

which one we need to use?

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Fri, 19 Oct 2018 12:58:53 GMT

Did you place the example project in the correct level inside the SDK and the directory where the mpu files are located?

You should have the mpu library files located in [SDK_ROOT]\examples\nrf5-mpu-examples\, and your SES project should be located in [SDK_ROOT]\examples\nrf5-mpu-examples\nrf5-ble-mpu-simple\pca10040\s132\ses

From your original image, it looks like you have the project and library files located in a wrong path level.

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'

Hi,

I command the sensorsim.h header file..

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

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Wed, 17 Oct 2018 14:56:23 GMT

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,

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?

RE: MPU6050 with NRF52832 in segger

Jørgen Holmefjord — Wed, 17 Oct 2018 09:00:23 GMT

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.
