#defineLCD_Command*（*（volatileu80x6c000000
#defineLCD_Data*（*（volatileu80x6c000001（LCD数据宽度为8BIT
当数据写入LCD_Command对应的地址时地址和数据会分别被发送到对应的AFIO复用端口将AFIO的A0接至LCD的C/D（Command/data脚就自动切换了命令和数据
LCD_Command=0x55;
A0=0;
对应地址低位0x6c000000
LCD_Data=0x55;
A0=1;
对应地址低位0x6c000001
此开发板LCD与MCU的引脚对应关系为:
D0---->
PD14D4---->
PE7A0------>
PF00
D1---->
PD15D5---->
PE8FSMC_NE4------>
PG12
D2---->
PD0D6---->
PE9FSMC_NWE------->
PD5
D3---->
PD1D7---->
PE10FSMC_NOE------->
PD4
本例中所有引脚配置为AFIO
程序如下:
对于FSMC的工作模式时序配置可以看手册的18章
