本文主要是介绍#Cubemx配置FSMC驱动IL9341，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、IDE：keil、cubemx、Arduino.........
二、设备：stm32f103zet6
三、记录：
（1）原理图
（2）配置cubemx
a.swd、rcc、时钟72M
b.配置FSMC
c.配置背光，复位
这里由于我的屏幕复位与单片机复位按键在一起，所以不配置了。
d.生成工程
（3）移植驱动代码
FSMC_LCD_ILI9341 · lovefoolnotme/单片机驱动代码开源 - 码云 - 开源中国 (gitee.com)
a.将驱动代码拷贝过来加入，同时设置优化等级降低为0，不然会出现不能显示，只亮背光的问题。
b.驱动代码修改
在最初这个驱动代码是由标准库移植过来的，需要进行适当修改才能使用。
主要修改为u8,u16,u32,delay_ms等，可修改为uint8_t,uint16_t,uint32_t以及HAL_Delay。
上面代码仓库里面已经修改。
想要大面积修改某一单词时，使用ctrl+f快速replace或者find查找单词。
（4）特别注意
在编写由cubemx编写的代码时需要将代码写在begin和end之间，否则更新cubemx配置时会被去除。
（5）运行效果
四、代码：
