控制/MCU
1、FSMC初初了解:
FSMC 包括4个模块:
(1)AHB接口(包括FSMC配置寄存器)
(2)NOR闪存和PSRAM控制器(驱动LCD的时候LCD就好像一个PSRAM的里面只有2个16位的存储空间,一个是DATA RAM 一个是CMD RAM)
(3)NAND闪存和PC卡控制器
(4)外部设备接口
我们驱动TFT很明显用的是第二个模块:NOR闪存。
2、FSMC的外设地址选择
FSMC _Bank 用来选择外接存储器的地址,FSMC所控制的外存储器所映射的地址是0x6000 0000 ~ 0x9fff ffff
其中属于NOR FLASH 的是0x6000 0000 ~ 0x6fff ffff ,然后这部分的地址空间又被分为四份,每份64MB, 编号是BANK1 ~ BANK 4 ,每个BANK 都有一个片选引脚。
而这四个分存储块的片选,则使用NE[4:1]来选择。数据线/地址线/控制线是共享的。
NE1 ->Bank1 NE2->Bank2 NE3->Bank3 NE4->Bank4
第一块:6000 0000h--63ff ffffh
第二块:6400 0000h--67ff ffffh
第三块:6800 0000h--6bff ffffh
第四块:6c00 0000h--6fff ffffh
3、FSMC 驱动LCD
FSMC提供了所有的LCD控制器的信号:
FSMC_D[16:0]:16bit的数据总线
FSMC NEx:分配给NOR的256M,再分为4个区,每个区用来分配一个外设,这四个外设的片选分为是NE1-NE4,对应的引脚为:PD7—NE1,PG9—NE2,PG10-NE3,PG12—NE4
FSMC NOE:输出使能,连接LCD的RD脚。
FSMC NWE:写使能,连接LCD的RW脚。
FSMC Ax:用在LCD显示RAM和寄存器之间进行选择的地址线,即该线用于选择LCD的RS脚,该线可用地址线的任意一根线,范围:FSMC_A[25:0]。
正如我们操作12864的命令/数据选择端口RS一样,对于FSMC驱动TFT :RS = 0时,表示读写寄存器;RS = 1表示读写数据RAM。
4、GPIO端口配置
由于是使用FSMC来驱动TFT的,所以除了背光用的PD13和复位用的PC1要设置为通用推挽输出之外,其他引脚都必须设置为复用推挽输出。然而,很奇怪的是。当我配置好PD13时,我发现程序下载进去后是一片漆黑的,后来再三检查是背光的PD13的问题。必须把PD13置高才可以亮,否则默认低电平,就是一片黑了。

配置好相应的IO为推挽输出,硬件初始化即可。不过这里需要注意的是,这里使用GPIOB作为I80总线数据口,所以和Jtag口冲突(详见:stm32 最小系统 中jtag说明)。所以在配置IO时要将 jtag口的IO复用关闭:
[cpp] view plain copy在GPIO_Configuration()配置中:
GPIO_PinRemapConfig(GPIO_Remap_SWJ_Disable, ENABLE);
// 改变指定管脚的映射 GPIO_Remap_SWJ_Disable SWJ 完全禁用(JTAG+SW-DP);必须加上这句,否则会导致串口无法使用 被折腾了很久 原因不详
GPIO_PinRemapConfig(GPIO_Remap_SWJ_JTAGDisable , ENABLE);
// 改变指定管脚的映射 GPIO_Remap_SWJ_JTAGDisable ,JTAG-DP 禁用 + SW-DP 使能
注意:不要忘记在RCC_Configuration()中开启AFIO时钟,//AFIO时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);
在main.c中直接调用相关函数:
[cpp] view plain copyint main(void)
{
//stm32 初始化
RCC_Configuration();
NVIC_Configuration();
USART_Configuration();
SPI_Configuration();
GPIO_Configuration();
LCD_Init();
POINT_COLOR = BLACK; //设置字体颜色
LCD_ShowString(30,50,“Hello Dog 。. ”);
printf(“\r\n test.。 \r\n”);
while(1);
}
