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
}

    In general there should not be any issue with using delays in the application. Do you get any warnings when compiling? Is the issue only present when debugging the application, or always when the delay function is used?

    Can you post higher resolution screenshot? Are you using BLE in your application?

    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?

    thank you for your reply!

    I will post the whole project with a drop box.

    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!
