Hi，

The following error occurred after I followed your steps.

Hi,

I am not sure if it is Keil or a general guide, but the steps to do this in SES are as follows:

Open the example project in SES
Right click on the project, Project '<project_name>_pca10056_s140' and select Options.... Make sure you have selected Common as configuration, and not Debug or Release in the upper left.
Go to Debugger and change the following:
1. Target Device to nRF52833_xxAA
2. Register Definition File to the file nrf52833.svd
Go to Preprocessor in the menu on the left in Options and open Preprocessor Definitions. Change the following:
1. NRF52840_XXAA -> NRF52833_XXAA
2. BOARD_PCA10056 -> BOARD_PCA10100
Go to Linker and open Section Placement Macros. Adjust the RAM and flash size of nRF52833.
Close Options and, in the project explorer on the left, go to Project '<project_name>_pca10056_s140' -> None and remove system_nrf52840.c and ses_startup_nrf52840.s, and add the files for nRF52833 instead. These files are located in <SDK_ROOT>/modules/nrfx/mdk

Best regards,

Marte

Hi,

The heart rate application is not supported on the nRF52833 out of the box, unfortunately. If you look in the example folder, you will find that there is no project file or Makefile for nRF52833. There is a project file for nRF52840, which use SoftDevice S140. This SoftDevice is supported on nRF52833, so you can try transferring the nRF52840 project to a nRF52833 project. To do so, you can follow the guide in Transferring the project to nRF52810 hardware. This guide is originally for nRF52810, so remember to change the preprocessor settings and linker script to match nRF52833 and not nRF52810.

Best regards,

Marte

But the S132 protocol stack is used in Heart Rate Application with FreeRTOS, and the nrf52833 can only be compatible with the protocol stack shown in the figure below，I will use nrf52833 as a peripheral，Is there any problem with nrf52833 running Heart Rate Application with FreeRTOS?

Hi,

Yes, the nRF52833 can run FreeRTOS. You can read more about FreeRTOS in nRF5 SDK here: nRF5 SDK FreeRTOS support. The SDK has two examples using FreeRTOS already, the Blinky FreeRTOS example and the Heart Rate Application with FreeRTOS.

Best regards,
