原子大哥：
   最近在调试VS1053B芯片的时候，发现STM32F767 HAL库SPI1无法发送和接收数据，我看了你的几个例程都是用IO模拟的，请问是不是HAL库有什么问题呢？

代码如下: (引脚配置代码没贴上来)

void VS1053B_SPI1_Config(void)
{
      SPI_HandleTypeDef  SpiHandle;

      SpiHandle.Instance             = SPI1;
      SpiHandle.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_128;
      SpiHandle.Init.Direction       = SPI_DIRECTION_2LINES;
      SpiHandle.Init.CLKPhase       = SPI_PHASE_1EDGE;
      SpiHandle.Init.CLKPolarity    = SPI_POLARITY_HIGH;
      SpiHandle.Init.DataSize       = SPI_DATASIZE_8BIT;
      SpiHandle.Init.FirstBit       = SPI_FIRSTBIT_MSB;
      SpiHandle.Init.TIMode          = SPI_TIMODE_DISABLE;
      SpiHandle.Init.CRCCalculation = SPI_CRCCALCULATION_DISABLE;
      SpiHandle.Init.CRCPolynomial    = 7;
      SpiHandle.Init.NSS             = SPI_NSS_SOFT;
      SpiHandle.Init.Mode             = SPI_MODE_MASTER;

      HAL_SPI_Init(&SpiHandle);

}

uint8_t VS1053B_SPI1_SendByte(uint8_t Byte)
{
      HAL_SPI_Transmit(&SpiHandle, &Byte, 1, 500);
}

uint8_t VS1053B_SPI1_ReadByte(void)
{
      uint8_t receive_data = 0;

      HAL_SPI_Receive(&SpiHandle, &receive_data, 1, 500);

      return receive_data;
}

数据发送和接收都有问题，不知道怎么回事。
