nrf51822 - heart rate monitor demo compilation problems.

[nullpointer]

Dear all, I am following the user guide nRF51822_Evaluation_Kit User_Guide v1.2.pdf When I try to compile the example C:\Keil_v5\ARM\Device\Nordic\nrf51822\Board\pca10001\s110\ble_app_hrs\arm\ble_app_hrs.uvproj using the Keil_v5 evaluation tool. I got these errors :

I guess I could try to fix the path of the referenced library

C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Include\core_cm0.h

C:\Keil_v5\ARM\Device\Nordic\nrf51422\Include\nrf51.h

anyway, I would like to know what would be the cleanest way to fix it.

Thanks and Kind Regards,

Have you tried to reinstall the Keil MDK-ARM? Did you follow the steps in the quick start guide?

[Krzysztof Loska]

Hi, An important message from Keil is that from version 5.12 of Keil IDE projects in the old format (.uvproj) are not supported any more (in more details are supported only with the Legacy Installer which copies certain files into specified locations). Projects in the new format (.uvprojx) should be used instead. If someone after all wants to use the old format (.uvproj) in Keil 5.12 or higher, should install, along with nRF_DeviceFamilyPack, the MDKCM Add-On Installer from: www.keil.com/mdk5/legacy.

It works fine using .uvprojx Thanks
