How to include existing header files to main.c?

[MRafiq9748]

Hello.

I want to integrate UART and SPI ,I am using SDK15.2. The problem here is i am not able to add app_uart.h to main.c(spi).

My question here is how to add it to main,c? 

I am using Keil uVision.

Thanks in Advance.

Hi

You can't use UART as both application and log backend. I suspect you might have both enabled in sdk_config.h. You will have to set NRF_LOG_BACKEND_UART to 0 and alternatively use RTT as your backend. If you are having further trouble, please post your sdk_config.h file so I can have a look at it.

Best regards,

Simon
