Hello,
I'm trying to configure my BF707 as a SPI Slave, though getting the error ADI_SPI_CONFIGURATION_ERROR from adi_spi_SetSlaveSelect()
Below is my code:
// configure and de-assert the GPIO chip-selects for the boot eeprom
ADI_GPIO_RESULT gResult;
// configure SPI bus for the boot eeprom
ADI_SPI_RESULT sResult;
sResult = adi_spi_Open(SPI_FACEPLATE_BUS, SPIDriverMemory,sizeof(SPIDriverMemory), &g_hSpiDevice );
assert (sResult == ADI_SPI_SUCCESS );
//@todo eventually need to set this false to be slave
sResult = adi_spi_SetMaster( g_hSpiDevice, false );
assert (sResult == ADI_SPI_SUCCESS );
//@todo this might need to be true for slave mode
sResult = adi_spi_SetHwSlaveSelect( g_hSpiDevice, false );
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetTransmitUnderflow( g_hSpiDevice, true );
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetClockPhase( g_hSpiDevice, false );
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetClock( g_hSpiDevice, 1000u );
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetSlaveSelect( g_hSpiDevice, ADI_SPI_SSEL_ENABLE1 );
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetWordSize( g_hSpiDevice, ADI_SPI_TRANSFER_8BIT );
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetTxWatermark( g_hSpiDevice,
ADI_SPI_WATERMARK_50,
ADI_SPI_WATERMARK_DISABLE,
ADI_SPI_WATERMARK_DISABLE);
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_SetRxWatermark( g_hSpiDevice,
ADI_SPI_WATERMARK_50,
ADI_SPI_WATERMARK_DISABLE,
ADI_SPI_WATERMARK_DISABLE);
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_RegisterCallback( g_hSpiDevice, &SpiDmaCallback, NULL);
assert (sResult == ADI_SPI_SUCCESS );
sResult = adi_spi_EnableDmaMode( g_hSpiDevice, true );
assert (sResult == ADI_SPI_SUCCESS );
I can't seem to find an example of using SPI in slave mode anywhere.
