Getting SPI to work

Kolijn Wolfaardt

Hi, I'm using a MCBSTM32E board, with a ST32E103ZE Arm Cortex M3 processor. I am trying to get the SPI interface to work, but so far I've had no luck.

I've tried simulating, and capturing the pin outputs with an oscilloscope, but I get no output.

Relevant code:

void M_SPIInit(void)
{
        SPI_InitTypeDef SPI_InitStructure;

        // SPI1 configuration
        SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
        SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
        SPI_InitStructure.SPI_DataSize = SPI_DataSize_16b;
        SPI_InitStructure.SPI_CPOL = SPI_CPOL_High;
        SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge;
        SPI_InitStructure.SPI_NSS = SPI_NSS_Hard;
        SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;
        SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
        SPI_InitStructure.SPI_CRCPolynomial = 7;
        SPI_Init(SPI1, &SPI_InitStructure);
}

int main (void)
{
        stm32_Init();
        M_SPIInit();
        SPI_Cmd(SPI1, ENABLE);
        SPI_I2S_SendData(SPI1,word);
}
