Can't instantiate uart driver

hello, that's compile, I also modify this code part :

typedef struct
{
    union
    {
#if (defined(UART_IN_USE) || (UART_ENABLED == 0))
    NRF_UART_Type * p_uart;   ///< Pointer to a structure with UART registers.
#endif
#if (defined(UARTE_IN_USE))
    NRF_UARTE_Type * p_uarte; ///< Pointer to a structure with UARTE registers.
#endif

    } reg;
    uint8_t drv_inst_idx;     ///< Driver instance index.
} nrf_drv_uart_t;

and I suppress the p_uart = in the NRF_DRV_UART_INSTANCE macro. As I said, the program compile, but it didn't work, this is my main function :

#define BSP_UART_SUPPORT #include "bsp.h" #include "sdk_config.h" #include "nrf_delay.h"

#include "nrf_drv_uart.h"

const nrf_drv_uart_t uart_test = NRF_DRV_UART_INSTANCE(0);

void uart_event_handler(nrf_drv_uart_event_t * p_event, void * p_context) { //static uint8_t rec_byte=0; switch(p_event->type) { case NRF_DRV_UART_EVT_RX_DONE:

    break;

    case NRF_DRV_UART_EVT_ERROR:

    default:
    break;
}

}

int main(void) {

/*Parameters for uart driver*/
uint32_t err_code;
nrf_drv_uart_config_t uart_cfg;

uart_cfg.pseltxd        = RX_PIN_NUMBER;
uart_cfg.pselrxd        = TX_PIN_NUMBER;
uart_cfg.pselcts        = RTS_PIN_NUMBER;
uart_cfg.pselrts        = CTS_PIN_NUMBER;
uart_cfg.hwfc           = NRF_UART_HWFC_DISABLED;
uart_cfg.parity         = NRF_UART_PARITY_EXCLUDED;
uart_cfg.baudrate       = NRF_UART_BAUDRATE_115200;
uart_cfg.use_easy_dma   = true;

err_code = nrf_drv_uart_init(&uart_test,&uart_cfg,uart_event_handler);
APP_ERROR_CHECK(err_code);
nrf_drv_uart_rx_enable(&uart_test);
uint8_t test[4]={0,255,0,255};
static uint8_t i=0;

while( true )
{
  while(i<4)
  {
      err_code = nrf_drv_uart_tx(&uart_test, &test[i], 1);
      if(err_code ==NRF_SUCCESS )
      {
      }
      nrf_delay_ms(1000);
      i++;
  }
  i=0;
};
return 0;

}

in the oscilloscope, I don't have any signal in Tx output pin :/

What if you do:

#define NRF_DRV_UART_INSTANCE(id)                            \
{                                                            \
    .reg          = {p_uart = NRF_DRV_UART_PERIPHERAL(id)},           \
    .drv_inst_idx = CONCAT_3(UART, id, _INSTANCE_INDEX),\
}

#define NRF_DRV_UART_INSTANCE(id)                            \
{                                                            \
    .reg          = {p_uart = (NRF_UART_Type*)NRF_DRV_UART_PERIPHERAL(id)},           \
    .drv_inst_idx = CONCAT_3(UART, id, _INSTANCE_INDEX),\
}

instead of

#define NRF_DRV_UART_INSTANCE(id)                            \
{                                                            \
    .reg          = {NRF_DRV_UART_PERIPHERAL(id)},           \
    .drv_inst_idx = CONCAT_3(UART, id, _INSTANCE_INDEX),\
}

because I instatiate differently my UART : uart_inst.drv_inst_idx = CONCAT_3(UART, 0, _INSTANCE_INDEX); but I am not sur that's the right way to instatiate the program!

You said "That's compile"

RE: Can't instantiate uart driver

acha — Wed, 28 Dec 2016 13:16:41 GMT

No! because, the program didn't compile :/

Petter Myhre — Wed, 28 Dec 2016 13:15:13 GMT

And the UART works? It looks similar to what is suggested here.

I use g++ in my code!

RE: Can't instantiate uart driver

Petter Myhre — Wed, 28 Dec 2016 11:58:39 GMT

You are using C++? Should you then use g++ not gcc? I just tried to compile with gcc and I don't get any errors with the code in my answer.

I did! it was an error of compressing file, I juste add sdk_config file, and the compiler name, all the project is heavy!

The zip you uploaded only contains one empty folder. What toolchain are you using?

RE: Can't instantiate uart driver

Petter Myhre — Wed, 28 Dec 2016 09:35:56 GMT

Ok. What toolchain are you using? Could you share your complete project so I can test it here? You can edit your original question and upload it there.

I tried this solution, but the error persist, I still have this error message :

sdk/components/drivers_nrf/uart/nrf_drv_uart.h:97:1: error: invalid conversion from 'void*' to 'NRF_UARTE_Type*' [-fpermissive] } ^ drivers/uart.hpp:20:29: note: in expansion of macro 'NRF_DRV_UART_INSTANCE' const nrf_drv_uart_t uart = NRF_DRV_UART_INSTANCE(0);

RE: Can't instantiate uart driver

Petter Myhre — Wed, 28 Dec 2016 09:20:43 GMT

You should do something like this:

#include "nrf_drv_uart.h"

const nrf_drv_uart_t uart = NRF_DRV_UART_INSTANCE(0);

void uart_event_handler(nrf_drv_uart_event_t * p_event, void * p_context)
{
}

void initUART()
{
    uint32_t err_code;
    nrf_drv_uart_config_t uart_cfg;

    uart_cfg.pseltxd        = RX_PIN_NUMBER;
    uart_cfg.pselrxd        = TX_PIN_NUMBER;
    uart_cfg.pselcts        = RTS_PIN_NUMBER;
    uart_cfg.pselrts        = CTS_PIN_NUMBER;
    uart_cfg.hwfc           = NRF_UART_HWFC_DISABLED;
    uart_cfg.parity         = NRF_UART_PARITY_EXCLUDED;
    uart_cfg.baudrate       = NRF_UART_BAUDRATE_115200;
    uart_cfg.use_easy_dma   = true;

    err_code = nrf_drv_uart_init(&uart, &uart_cfg, uart_event_handler);
    APP_ERROR_CHECK(err_code);
    nrf_drv_uart_rx_enable(&uart);
}

RE: Can't instantiate uart driver

hello again; I made a modification, I instantiate separatly the uart declaration and the instance index, as bellow :

void initUART()
{
    nrf_drv_uart_t uart_inst;
    uart_inst.drv_inst_idx = CONCAT_3(UART, 0, _INSTANCE_INDEX);

    uint32_t err_code;
    nrf_drv_uart_config_t uart_cfg=NRF_DRV_UART_DEFAULT_CONFIG;

    uart_cfg.pseltxd=RX_PIN_NUMBER;
    uart_cfg.pselrxd=TX_PIN_NUMBER;
    uart_cfg.pselcts=RTS_PIN_NUMBER;
    uart_cfg.pselrts=CTS_PIN_NUMBER;
    uart_cfg.hwfc=(nrf_uart_hwfc_t)UART_CONFIG_HWFC_Disabled;
    uart_cfg.parity=(nrf_uart_parity_t)false;
    uart_cfg.baudrate=(nrf_uart_baudrate_t)UART_BAUDRATE_BAUDRATE_Baud115200;

    err_code = nrf_drv_uart_init(&uart_inst, &uart_cfg, uartEventHandler);
    nrf_drv_uart_rx_enable(&uart_inst);
    APP_ERROR_CHECK(err_code);
}

That's compile, but i don't know that i made the right instantiation? o_O
