UART

[Nils Minor]

Hi,

is there any Example to use the UART ? I need an monitor while the application is running, is the UART COM Port the right one for this?

Is there an example with the app_uart?

Best regards Nils

You just need to add simple_uart.c to your project and include simple_uart.h headers.

I generally use:

simple_uart_putstring("Some text\r\n");

To send my debugging output.

If you're using the nRF51822-EK, configure the onboard USB UART with:

simple_uart_config (0, 9, 0, 11, false):

And set your baud rate on your terminal program to 38.4K and find the USB CDC serial port that should appear.

I'm embarrassed to say that I didn't even clue-in to the onboard CDC emulation at first :-/

Hope that helps.

@Yalcim , connecting to printf is fairly well explained in the Keil documentation, but I don't know how to do it for GCC.

Although not a perfect solution, if you have simple_uart_putstring() working, then you can do this:

[b] uint8_t text_buffer[128];

sprintf( text_buffer, "Formatted answer  %8d   %8.3f\n\r",
                        intvar,  floatvar);

simple_uart_putstring( text_buffer );[/b]

Yes the way Yalcin told you is the right way. You have to comment the #define out. If it does not work i can send you my code tomorrow.

@Philip, I tried using sprintf(). I confirmed that no problem about int type. but, the float type of the %f don't be seen on screen. How can I solve this problem?
