STM32學習筆記——TFT2.4彩屏顯示圖片

彩屏的驅(qū)動程序如果寫好的話，就可以一直使用了，精力主要集中在應(yīng)用程序的編寫就可以了，但是移植的話，要移植驅(qū)動程序。其實移植也只是改變那些很底層的靠近處理器的那部分代碼。

因為STM32F103C8的片上只有64K的FLASH，所以不能存儲太多的圖片數(shù)據(jù)，也就不能顯示太大的圖片。

一下的程序注釋的比較詳細，看懂了基本上就可以用了。

彩屏驅(qū)動程序的頭文件lcd.h如下：

#defineucharunsignedchar

#defineuintunsignedint

#defineBus_16//16位數(shù)據(jù)模式,如果使用8位模式，請注釋此語句，如果使用16位模式，請打開此句

#defineLCD_DataPortHP1//高8位數(shù)據(jù)口,8位模式下只使用高8位

#defineLCD_DataPortLP0//低8位數(shù)據(jù)口,8位模式下低8位可以不接線

#defineLCD_WRGPIO_Pin_2//WR引腳定義P2^5

#defineLCD_RSGPIO_Pin_1//RS引腳定義P2^6

#defineLCD_CSGPIO_Pin_0//CS引腳定義P2^7

#defineLCD_RSTGPIO_Pin_11//RST引腳定義P3^3

#defineLCD_RDGPIO_Pin_8//RD引腳定義P3^2

#defineLCD_SIZE_X240

#defineLCD_SIZE_Y320

externuintcolors[];

externvoidpic_play(uintxStart,uintxEnd,uintyStart,uintyEnd);//顯示圖片函數(shù)

voiddelayms(intcount);

//voidLCD_Writ_Bus(charVH,charVL);

voidLCD_Init(void);

voidLCD_Writ_Bus(uintVH,uintVL);

voidLCD_Write_COM(charVH,charVL);

voidLCD_Write_DATA(charVH,charVL);

voidPant(charVH,charVL);

voidAddress_set(unsignedintx1,unsignedinty1,unsignedintx2,unsignedinty2);

驅(qū)動程序lcd.c文件如下：

#include"stm32f10x_lib.h"

#include"Lcd.h"

//存儲圖片數(shù)據(jù)的頭文件

//#include"picture.h"

#include"picture_sara.h"

#include"xiaoqian.h"

#include"yang.h"

#defineLCD_rest(x)x?GPIO_SetBits(GPIOA,LCD_RST):GPIO_ResetBits(GPIOA,LCD_RST)//自己定義位操作函數(shù)

#defineLCD_rd(x)x?GPIO_SetBits(GPIOA,LCD_RD):GPIO_ResetBits(GPIOA,LCD_RD)

#defineLCD_rs(x)x?GPIO_SetBits(GPIOB,LCD_RS):GPIO_ResetBits(GPIOB,LCD_RS)

#defineLCD_wr(x)x?GPIO_SetBits(GPIOB,LCD_WR):GPIO_ResetBits(GPIOB,LCD_WR)

#defineLCD_cs(x)x?GPIO_SetBits(GPIOB,LCD_CS):GPIO_ResetBits(GPIOB,LCD_CS)
