How to turn on the BSP UART

[Glenn]

Hello,

I am altering this project: nRF51_SDK_8.0.0_5fc2c3a\examples\ble_peripheral\ble_app_hrs\pca10028

I am trying to turn on the BSP UART. I main.c the project uses bsp_init() to enable the buttons and leds.

I just want to use the UART so I modified the bsp_init() to this:

err_code = bsp_init(BSP_INIT_UART,
                    APP_TIMER_TICKS(100, APP_TIMER_PRESCALER),
                    NULL);	
APP_ERROR_CHECK(err_code);

Then I have an output message using this function:

  err_code = bsp_indication_text_set(BSP_INDICATE_SENT_OK, "Test UART Output\n\r");
  APP_ERROR_CHECK(err_code);

Putting a breakpoint inside the bsp_indication_text_set() function on the printf statment, I am not able to get it to stop on the printf statement.

uint32_t bsp_indication_text_set(bsp_indication_t indicate, char const * p_text)
{
    uint32_t err_code = bsp_indication_set(indicate);

#ifdef BSP_UART_SUPPORT
    printf("%s", p_text);                            // Set breakpoint here
#endif // BSP_UART_SUPPORT

    return err_code; 
}

I am guessing BSP_UART_SUPPORT is not set properly to execute the printf statement.

Am I not turning on the BSP UART correctly?

I added #define BSP_UART_SUPPORT 1

#ifdef BSP_UART_SUPPORT
    printf("%s", p_text);
#endif // BSP_UART_SUPPORT

return err_code;

I put a breakpoint on the printf statement and the return statement. The debugger stops at t the printf. I take the next step in the code and it does not stop on the return statement. I believe there is some issue with the uart and the printf statement is not executing properly.

Thanks, Glenn

Have you defined BSP_UART_SUPPORT? If not, then there's no BSP UART support.

update #1:

So you set a breakpoint at printf and it stops, then you single step. What happens next, does the debugger stop again or just keep running? If it stops, where does it stop, if it keeps running, hit the break button and find out where it is.

I added

#define BSP_UART_SUPPORT	1
#ifdef BSP_UART_SUPPORT
printf("%s", p_text);
#endif // BSP_UART_SUPPORT
return err_code;

Don't #define it, make it a project define like all the examples do. That ensures that all your code sees the define.

When you hit the break button where does the debugger show you are (that was the second part of the original reply).
