Why when i compile a proyect the files .h not being created?

[Pablo]

I use nRF51 DK and soft device s130.

I nedd to add a file ("app_uart_fifo.c") in the example of multilink central, after i add the file i build the proyect but the files .h never being created. I have to do something more?

You need to include the app_uart.h file to your project and add the path to the header file:

• In Keil, go to Project -> Options for target
• In the C/C++ tab, add ..\..\..\..\..\..\components\libraries\uart\ to the include path.
• Include app_uart.h to the project by writing #include "app_uart.h" near the top of the main.c file (or in whatever file you will be using the UART library).

Jorgen i just do that, but this don't solve my problem.

I have to use the function "app_uart_put()". I write an answer more explicit above

If you want to use printf() function for UART, you need to add retarget.c to your project as well.
