本文共 23588 字，大约阅读时间需要 78 分钟。

开发板：野火指南者（STM32F103VE）

STM32库版本：STM32F10x_StdPeriph_Lib_V3.5.0

IDE:KEIL5（代码编写很不方便，只在编译的时候用到）

代码编写工具：Source Insight 4.0（跟读代码、编写代码的最佳工具）

硬件原理图：

1. 新建user_fsmc_lcd.h、user_fsmc_lcd.c、main.c 3个文件，并从STM32官方库的例子中将stm32f10x_it.c、stm32f10x_it.h、stm32f10x_conf.h拷贝到自己的工程目录下。

2. 在user_fsmc_lcd.h中添加如下代码

1 #ifndef __USER_FSMC_LCD_H 2 #define __USER_FSMC_LCD_H 3  4 #include "stm32f10x.h" 5  6 #define LCD_CMD        ((uint32_t)0x60000000) 7 #define LCD_DATA    ((uint32_t)0x60020000) 8  9 #define TEXTCOLOR    0xF80010 #define BACKGROUND    0x000011 12 13 14 void time_delay(uint32_t t);    //时间延时函数15 void user_lcd_display_string(char * pchar);        //显示英文字符串函数16 void user_lcd_fill_color(uint32_t fill_lcd, uint16_t color);        //整个屏幕填充的颜色函数17 void user_lcd_clear(void);        //清屏函数，将屏幕配置为黑色18 void user_lcd_display_char(uint16_t x, uint16_t y, char ch);        //单个字符显示函数19 void user_View_Window(uint16_t lcd_x, uint16_t lcd_y, uint16_t lcd_width, uint16_t lcd_height);        //初始化整个屏幕20 void user_LCD_Init(void);        //LCD初始化函数21 void user_LCD_Scan(void);        //LCD扫描函数，这里配置为模式六，即X--240, Y--320，X从左到右，Y从上到下扫描22 void user_LCD_DATA(uint16_t data);        //LCD数据写入函数23 void user_LCD_CMD(uint16_t cmd);        //LCD命令操作函数24 void user_LCD_REG_Config(void);            //LCD对应的IC控制寄存器配置函数，这个配置与LCD上控制芯片相关，如何配置应该是向供应商获取的25 void user_FSMC_Config(void);        //FSMC配置函数26 void user_LCD_BL(FunctionalState Status);        //LCD背光信号控制函数27 void user_LCD_RST(FunctionalState Status);        //LCD复位信号控制函数28 void user_LCD_GPIO_Config(void);        //LCD相关GPIO PIN初始化函数29 30 31 32 #endif

3. 在user_fsmc_lcd.c中添加如下代码

4. 在main.c中添加如下代码

1 #include "stm32f10x.h" 2 #include "user_fsmc_lcd.h" 3  4  5 int main(void) 6 { 7     user_LCD_Init(); 8  9     //user_LCD_Scan();10 11     while(1)12     {13         user_lcd_clear();14 15         user_lcd_display_string("it's test!");16 17         time_delay(0xFFFFFF);18 19     }20 21 }

总结：

1. void user_LCD_REG_Config(void)这个LCD 控制寄存器配置没有搞清楚是要怎么配置，有可能直接是向ILI9341芯片厂商索取的

2. 本实验有个很奇怪的现象就是，每次开关开发的电源时，LCD会白屏一段时间，其多次开关后，会一直白屏，原因暂未找到
