stm32驱动LCD12864液晶屏驱动程序，亲测可行，复制直接能用！

废话不多说，直接贴程序，你自己复制过去即可，免得我通过把工程上传的方式，你下载还得需要c币，这个现在很贵呀！！！

就两个文件，LCD12864.h和LCD12864.c，自己复制过去后，改一下引脚即可

（如果你连改引脚都不会，那你看来是初初学者，那你自己百度吧），单片机主频：72MHZ

LCD12864.h如下所示

#ifndef __LCD12864_H #define __LCD12864_H #include "sys.h" #define LCD1602_RS PEout(0) // PE0 go define之后我们会发现，这个宏最后就是在这个io的地址这里赋值 // #define MEM_ADDR(addr) *((volatile unsigned long *)(addr)) #define LCD1602_RW PEout(1) // PE1 #define LCD1602_E PAout(3) // PA3 void LCD12864IO_Init(void); void LCD1602_DB_IO_outputMode(void); void LCD1602_DB_IO_inputMode(void); void write_LCD1602_DB(uint8_t data); uint8_t read_LCD1602_DB(void); void InitLcd1602(void); void LcdShowStr(unsigned char row, unsigned char column, unsigned char *str); void LcdWriteCmd(unsigned char cmd); void LcdShowImage(uint8_t x, uint8_t y, uint8_t w, uint8_t h, uint8_t *img); void LcdClearArea(uint8_t x, uint8_t y, uint8_t w, uint8_t h); //#ifndef _HE_ extern uint8_t HE[]; extern uint8_t QQ[]; extern uint8_t myVX[]; //#endif #endif

LCD12864.c如下所示：
