Hi

Have you enabled the NRFX_SPI_ENABLED as well as the instance you'd like to use in your sdk_config.h file? This is also necessary for the nrfx_spi_xfer file to work properly.

Best regards,

Simon

ALL WORK GREAT NOW SPI_RID(DisplayID); now in debug this line is going to unknown function [ UNKNOWN FUNCTION AT 0x000008C8] but i already defined this 

//
// Read the COG ID
//
uint8_t SPI_RID(uint8_t DisplayID) {
tbuf[0] = 0x71;
tbuf[1] = 0;
cs_low(DisplayID);
nrf_drv_spi_transfer(&m_spi_master_0, tbuf, 2, rbuf, 2);
cs_high(DisplayID);
return rbuf[1];
}
