彩屏的驅(qū)動(dòng)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(dòng)程序。其實(shí)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?yàn)镾TM32F103C8的片上只有64K的FLASH，所以不能存儲(chǔ)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(xì)，看懂了基本上就可以用了。

彩屏驅(qū)動(dòng)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)
