stm32cubemx的设计如下：

接线如下：

代码如下：

main.h

int main(void)
{
  /* USER CODE BEGIN 1 */

  /* USER CODE END 1 */

  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */

  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  MX_GPIO_Init();
  MX_SPI1_Init();
  /* USER CODE BEGIN 2 */
float t=0;
LCD_Init();//LCD初始化
LCD_Fill(0,0,LCD_W,LCD_H,WHITE);

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
/* USER CODE END WHILE */

/* USER CODE BEGIN 3 */
LCD_ShowChinese(0,0,"新年快乐",RED,WHITE,32,0);
LCD_ShowString(0,33,"Happy New Year!",BLUE,WHITE,32,0);
LCD_ShowString(0,66,"LCD_W:",RED,WHITE,32,0);
LCD_ShowIntNum(106,66,LCD_W,3,RED,WHITE,32);
LCD_ShowString(0,99,"LCD_H:",RED,WHITE,32,0);
LCD_ShowIntNum(106,99,LCD_H,3,RED,WHITE,32);
LCD_ShowFloatNum1(0,135,t,4,GREEN,WHITE,32);
t+=0.11;
LCD_ShowPicture(160,95,40,40,gImage_1);
  }
  /* USER CODE END 3 */
}

效果如下：
