STM32 SPI驱动TFT LCD

         利用STM32F030 的SPI驱动TFT LCD，我使用的LCD为240*320像素的2.4寸彩屏，驱动IC为ili9341,只需四根线即可点亮LCD，先贴上SPI配置吧,声明一下，F030的SPI配置和F103等的配置有些不一样

/*LCD SPI Init*/

 // GPIO_PinAFConfig(GPIOB, GPIO_PinSource12, GPIO_AF_0);
  GPIO_PinAFConfig(GPIOB, GPIO_PinSource13, GPIO_AF_0);//SCK PIN

  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;

  SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_2;
  SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
  SPI_InitStructure.SPI_CRCPolynomial = 7;
 

  SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
  SPI_Init(SPI2, &SPI_InitStructure);
 
  /* Initialize the FIFO threshold */
  SPI_RxFIFOThresholdConfig(SPI2, SPI_RxFIFOThreshold_QF);
 
  /* Enable the Rx buffer not empty interrupt */
 // SPI_I2S_ITConfig(SPI2, SPI_I2S_IT_RXNE, ENABLE);

  SPI_Cmd(SPI2, ENABLE);
 
  /* Configure the SPI interrupt priority */
//  NVIC_InitStructure.NVIC_IRQChannel = SPI2_IRQn;
//  NVIC_InitStructure.NVIC_IRQChannelPriority = 1;
//  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
//  NVIC_Init(&NVIC_InitStructure);
