Using app UART in my project

[mostafa]

Hi , 

I can compile and use the UART example but when I try to use it in my project I get some linking errors

I have copied and past all the sdk_config.h file to my project from UART example, again I get error finally 

I copied evene the main file of the example to my main file but still I get following errors:

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_uart_get (referred from main.o).

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_uart_init (referred from main.o).

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol app_uart_put (referred from main.o).

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol bsp_board_leds_init (referred from main.o).

Thanks for your quick reply.

Regards,

You have probably forgotten to enable the UART library (and maybe the FIFO library) in sdk_config.h. You can do it by adding these lines in sdk_config.h:

// <q> APP_FIFO_ENABLED  - app_fifo - Software FIFO implementation
 

#ifndef APP_FIFO_ENABLED
#define APP_FIFO_ENABLED 1
#endif

// <e> APP_UART_ENABLED - app_uart - UART driver
//==========================================================
#ifndef APP_UART_ENABLED
#define APP_UART_ENABLED 1
#endif

You can also look at the the sdk_config.h file in the peripheral/uart example to see how it is done.
