If delay is inserted after data transmission by SPI, it transits to default_handler

Kaito

Hi!

I am planning to port SPI sending and receiving functions to the sample code of ble_app_uart of SDK 14.0.0.

The transplant was finish, but when I am debugging,if I add a delay after sending data with SPI while debugging, it will transition to Default_handler.

The code running SPI and UART worked fine without problems.

Is it impossible to put a delay in ble's sample code?

best regards!!

void SPITxCommand(unsigned char Data)
{
nrf_gpio_pin_clear(22); //CS pin low
nrf_drv_spi_transfer(&spi, &Data, 1, NULL, NULL);
//nrf_delay_us(50);
nrf_delay_us(100); //error component
}

    thank you for your reply!

    This code has the function of BLE, we use it to confirm data transmission with smartphone.

    I added the function from SPI sample code, but added the following function to config.h.

    Is it a problem that you are using an SPI that is not in the selection frame of the default handler below?

    Hi!

    While doing debugging, I found that the next instruction using the nrf_drv_spi_transfer function transitions to default handler.

    Does that mean that ble's sample code has missing files such as SPI C files and libraries?

     best regards!

    There is an error in your sdk_config.h file. You have set SPI0_ENABLED to 0 and SPI1_ENABLED to 1, but in your code you use SPI0 when declaring the SPI instance (NRF_DRV_SPI_INSTANCE(0)). The SPI0 IRQ handler is not compiled in and will default to the Default_Handler.
