nRF52832, SDK17.1, s132
I work with SPI and it works on the this project with SDK15.
But I have transferred this prj to the SDK17.1 and I can't make SPI work.
I don't get
spi_event_handler
where I set
spi_xfer_done
flag.
here are my code with SPI init

if (lis3dh_read(CTRL_REG1) != 0x2F)
{
lis_spi_error = 10;
}
// nrf_drv_spi_uninit(&spi);
}
And sdk_config.h where I set for SPI
What possible reason?
Thanks.
