SPI_CS has a wrong pin number on the picture

Hi, the definition of the SPI Pin CS is as follow 

const PinMap PinMap_SPI_SSEL[] = {
    {PA_4,  SPI_1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_NOPULL, GPIO_AF0_SPI1)},
    {PA_15, SPI_1, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_NOPULL, GPIO_AF0_SPI1)},
    {PB_12, SPI_2, STM_PIN_DATA(STM_MODE_AF_PP, GPIO_NOPULL, GPIO_AF0_SPI2)},
    {NC,    NC,    0}

this means the PB_6 is wrong if you choose that and the SPI will not work. Please fix that in the picture

The same mistake is there in the code .. the definition of the pins as bellow 

    // Standardized button names
    BUTTON1 = USER_BUTTON,
    SERIAL_TX   = PA_2,
    SERIAL_RX   = PA_3,
    USBTX       = PA_2,
    USBRX       = PA_3,
    I2C_SCL     = PB_8,
    I2C_SDA     = PB_9,
    SPI_MOSI    = PA_7,
    SPI_MISO    = PA_6,
    SPI_SCK     = PA_5,
    SPI_CS      = PB_6,
    PWM_OUT     = PC_7,
