5.Free RTOS配置

 6.touchGFX配置

三、touchGFX Designer配置

图片配置

 界面配置，界面包含一个主界面和三个次界面。主界面包含三个按钮，按钮增加和页面跳转功能；分界面包含一个图片和一个返回按钮，返回按钮可以返回主界面。

四、软件配置

1.去掉MicroLIB选项和下载校准选项

 2.增加下载算法

 3.增加代码段

五、增加代码

1.在TouchGFXHAL.cpp中增加代码

2.在TouchFGXCongratulation.cpp中增加代码

3.在STM32TouchController.cpp中增加触控代码

 4.SDRAM初始化

void MX_SDRAM_InitEx(void)
{
  __IO uint32_t tmpmrd = 0;
  
	FMC_SDRAM_CommandTypeDef Command;
	
  /* Step 1: Configure a clock configuration enable command */
  Command.CommandMode            = FMC_SDRAM_CMD_CLK_ENABLE;
  Command.CommandTarget          =  FMC_SDRAM_CMD_TARGET_BANK1;
  Command.AutoRefreshNumber      = 1;
  Command.ModeRegisterDefinition = 0;
 
  /* Send the command */
  HAL_SDRAM_SendCommand(&hsdram1, &Command,0X1000);
 
  /* Step 2: Insert 100 us minimum delay */ 
  /* Inserted delay is equal to 1 ms due to systick time base unit (ms) */
  osDelay(1);
    
  /* Step 3: Configure a PALL (precharge all) command */ 
  Command.CommandMode            = FMC_SDRAM_CMD_PALL;
  Command.CommandTarget          = FMC_SDRAM_CMD_TARGET_BANK1;
  Command.AutoRefreshNumber      = 1;
  Command.ModeRegisterDefinition = 0;
 
  /* Send the command */
  HAL_SDRAM_SendCommand(&hsdram1, &Command, 0X1000);  
  
  /* Step 4: Configure an Auto Refresh command */ 
  Command.CommandMode            = FMC_SDRAM_CMD_AUTOREFRESH_MODE;
  Command.CommandTarget          = FMC_SDRAM_CMD_TARGET_BANK1;
  Command.AutoRefreshNumber      = 8;
  Command.ModeRegisterDefinition = 0;
 
  /* Send the command */
  HAL_SDRAM_SendCommand(&hsdram1, &Command, 0X1000);
  
  /* Step 5: Program the external memory mode register */
  tmpmrd = (uint32_t)SDRAM_MODEREG_BURST_LENGTH_1          |\
                     SDRAM_MODEREG_BURST_TYPE_SEQUENTIAL   |\
                     SDRAM_MODEREG_CAS_LATENCY_3           |\
                     SDRAM_MODEREG_OPERATING_MODE_STANDARD |\
                     SDRAM_MODEREG_WRITEBURST_MODE_SINGLE;
 
  Command.CommandMode            = FMC_SDRAM_CMD_LOAD_MODE;
  Command.CommandTarget          = FMC_SDRAM_CMD_TARGET_BANK1;
  Command.AutoRefreshNumber      = 1;
  Command.ModeRegisterDefinition = tmpmrd;
 
  /* Send the command */
  HAL_SDRAM_SendCommand(&hsdram1, &Command, 0X1000);
  
  /* Step 6: Set the refresh rate counter */
  /* Set the device refresh rate */
  HAL_SDRAM_ProgramRefreshRate(&hsdram1, 683); 
}

 5.LTDC初始化

void LTDC_Init(void)
{
    HAL_LTDC_SetWindowPosition(&hltdc,0,0,0);  //设置窗口的位置
    HAL_LTDC_SetWindowSize(&hltdc,1024,600,0);//设置窗口大小 
	
    HAL_GPIO_WritePin(GPIOB, GPIO_PIN_5, GPIO_PIN_SET);//屏幕灯点亮
}

6.LCD线程

void LTCD_Thread(void const * argument)
{
    FT5206_Init();//触摸初始化
    osDelay(100);
    MX_TouchGFX_Process();
    
    while (1) {
        osDelay(10);
    }
}
