Hello LIU SHUANG,

that error usually means that the mbed library linked to the program is not up to date and does not include code needed for your target. Please verify the TARGET chosen in the online compiler and that the mbed library is up to date (update it to the newest revision).

I"m getting this same error both with mbed and mbed-src using the nRF51822 board. I just create a new program based on "Blinky LED Hello World", and It says it can't find device.h when I try to compile. I've made sure the mbed package is updated.

Brian, what revision is mbed lib? It's not just update, but have to go to Revision options where to switch to a newer version. Does that help?

It's showing that it's at revision 86, which looks to be the latest.

If I switch to revision 85 it compiles...

Looking at the changes, it looks like device.h for the nRF51822 was removed/moved in revison 86.

It seems to be working just fine when running in betamode (http://mbed.org/betamode/)

Did you import the "device" library device.h is refering to?

I Had.

Have you been able to get your programmed compiled? If not could you include a screenshot showing your workspace for your project?

Select the folder on the left side of the compiler: My Programs / blink_led / mbed-src / targets / hal / .... only the platform (board) for which compile "main.cpp". Other clear.
