100引腳的stm32f103v如何使用FSMC連接LCD

整合網(wǎng)絡(luò)資料，歸結(jié)如下

經(jīng)過(guò)查看數(shù)據(jù)手冊(cè)

RS可選為PD11 PD12 PD13任意一個(gè)。

上圖是貝一特科技的ze彩屏接口。

WR選PD5 ,RD選PD4 cs選則PD7.

關(guān)于其使用

//寫(xiě)16位數(shù)據(jù)函數(shù)
#define Bank1_LCD_D ((uint32_t)0x60020000) //disp Data ADDR
void LCD_WR_Data(unsigned int val)
{
*(__IO uint16_t *) (Bank1_LCD_D)= val;
}
將數(shù)據(jù)寫(xiě)到0x60020000這塊內(nèi)存上這個(gè)數(shù)據(jù)就會(huì)被STM32 同過(guò)FSMC硬件的發(fā)送到液晶控制器，不用自己干預(yù)?？梢岳斫鉃橐壕Э刂破鞯臄?shù)據(jù)入口被映射了0x60020000這塊內(nèi)存上。命令會(huì)到((uint32_t)0x60000000)。
用起來(lái)好用那如何配置呢？原先我就是覺(jué)得這麻煩放棄了..................
好了 在這用一個(gè)搞定FSMC的作為8080通信的全部配置。

為啥要這樣寫(xiě)？？寫(xiě)成別的樣子行不行？？？
FSMC有好幾個(gè)塊 每個(gè)塊映射的內(nèi)存也不一樣當(dāng)然不是只能寫(xiě)成這樣。要想詳細(xì)理解每個(gè)功能參數(shù)的意義要自己翻數(shù)據(jù)手冊(cè)了，在這寫(xiě)不下，只要理解 前邊的timing configuration試講時(shí)限的 后邊的是管時(shí)序的。改改timing configuration中的參數(shù)能讓時(shí)序完成的更快通信速度更快。

FSMC配置還后 液晶屏怎么連到單片機(jī)上？

FSMC是硬件的WR RD RS CS 這些都是指定好引腳的.
RD PD.04
WR PD.05
CS PD.07
RS PD.11
數(shù)據(jù)口 用了PE 和PD
這樣連接只適合前邊的FSMC的配置其他的配置引腳是會(huì)變的，可以看手冊(cè)來(lái)查查都是中文的......
這樣命令 和數(shù)據(jù) 的讀寫(xiě)可在 下邊的地址完成。
#define Bank1_LCD_D ((uint32_t)0x60020000) //disp Data ADDR
#define Bank1_LCD_C ((uint32_t)0x60000000) //disp Reg ADDR

//寫(xiě)寄存器地址函數(shù)
void LCD_WR_REG(unsigned int index)
{
*(__IO uint16_t *) (Bank1_LCD_C)= index;
}

//寫(xiě)寄存器數(shù)據(jù)函數(shù)
void LCD_WR_CMD(unsigned int index,unsigned int val)
{
*(__IO uint16_t *) (Bank1_LCD_C)= index;
*(__IO uint16_t *) (Bank1_LCD_D)= val;
}

//寫(xiě)16位數(shù)據(jù)函數(shù)
