STM32F429+W25Q256+TouchFGX

一、硬件介绍

硬件使用STM32F429IGT6，外部flash为W25Q256FVEI，屏幕为TFTLCD分辨率为1024*600，SDRAM使用的是W9825G6KH-6I。使用TouchGFX（版本为4.16.1）作为界面，外部falsh存储图片。

二、MXcube配置

1.时钟配置为

2.SDRAM配置为

3. DMA2D配置为

打开中断

4.LTDC配置为

 图层配置

打开中断

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);}
}
