SPI Prbolem , Clock dosen't work

[ToTo]

Why the SPI clk doesn't work, i checked using an oscilloscope :/ I also don't get any SPI interrupt and no data change in the RX buffer although I have wired MISO and MOSI

void vSensor_eInitSensor_Exe()
{
   /*Config SPI PINs*/
	  nrf_gpio_pin_set(SCLK_PIN); /*Initial state of CLK is High*/

      NRF_GPIO->PIN_CNF[SCLK_PIN] =
    (GPIO_PIN_CNF_DIR_Output        << GPIO_PIN_CNF_DIR_Pos)
  | (GPIO_PIN_CNF_INPUT_Connect     << GPIO_PIN_CNF_INPUT_Pos)
  | (GPIO_PIN_CNF_PULL_Disabled     << GPIO_PIN_CNF_PULL_Pos)
  | (GPIO_PIN_CNF_DRIVE_S0S1        << GPIO_PIN_CNF_DRIVE_Pos)
  | (GPIO_PIN_CNF_SENSE_Disabled    << GPIO_PIN_CNF_SENSE_Pos);
  // - MOSI (optional) - output with initial value 0,
      nrf_gpio_pin_clear(MOSI_PIN);
    nrf_gpio_cfg_output(MOSI_PIN);
  /* - MISO (mandatory) - input*/
  nrf_gpio_cfg_input(MISO_PIN, NRF_GPIO_PIN_NOPULL);
  /*Init SPI*/
  nrf_spim_pins_set(&stSPI_iNRF_SPI_Type,(uint32_t )SCLK_PIN, MOSI_PIN,(uint32_t )MISO_PIN);
  nrf_spim_frequency_set(&stSPI_iNRF_SPI_Type,NRF_SPIM_FREQ_125K);
  nrf_spim_configure(&stSPI_iNRF_SPI_Type,NRF_SPIM_MODE_0,CstSPI_iNrfSpiBitOrder);
  nrf_spim_rx_buffer_set(&stSPI_iNRF_SPI_Type,ui8RxBuffer,SPI_RX_BYTES_NB);
  nrf_spim_tx_buffer_set(&stSPI_iNRF_SPI_Type,ui8TxBuffer/*NULL*/,SPI_RX_BYTES_NB);
  nrf_spim_int_enable(&stSPI_iNRF_SPI_Type,NRF_SPIM_INT_STOPPED_MASK|NRF_SPIM_INT_ENDRX_MASK|NRF_SPIM_INT_STARTED_MASK); /*get events when RX done*/
  nrf_spim_enable(&stSPI_iNRF_SPI_Type);
  nrf_drv_common_irq_enable(SPIM_IRQ ,SPIM_CONFIG_IRQ_PRIORITY); /*enable SPI0 interrupt */
	stSPI_iNRF_SPI_Type.POWER=1;
 /*Create Periodic task for reading*/ 
  vSensor_iCreateReadingTask_Exe();
}

Here is the periodic task of reading

static void vSensor_iPeriodicReadHandler_Exe(void * p_context)
{
	 if(false==nrf_drv_gpiote_in_is_set(MISO_PIN))
	 { 
		 /*Clear interrupt flags & Lunch read transaction*/
		 nrf_spim_event_clear(&stSPI_iNRF_SPI_Type,NRF_SPIM_EVENT_ENDRX);
		 nrf_spim_task_trigger(&stSPI_iNRF_SPI_Type,NRF_SPIM_TASK_START);
		 app_timer_start(m_conversion_read_timer_id, PERIODIC_READING_INTERVAL, NULL);
	 }
	 else
	 {
		 /*empty else*/
	 }
	 
}

I tested your code and got it to work when I commented out //nrf_spim_int_enable(&stSPI_iNRF_SPI_Type, ...);. I used the SPI example in the SDK as a base (with the interrupt handler from the SPI driver). You should try to only run the SPI code to see if it works without the BLE stuff.

Also, in the interrupt handler you have to clear the event that triggered the interrupt:

if (nrf_spim_event_check(p_spim, NRF_SPIM_EVENT_END))
{
    nrf_spim_event_clear(p_spim, NRF_SPIM_EVENT_END);
}

Or else you will not get any more interrupts.
