吉林工程技术师范学院校徽的显示代码在51单片机l12864上

以下是基于51单片机的12864显示吉林工程技术师范学院校徽的示例代码：

#include <reg51.h>
#include <intrins.h>

#define LCD_PORT P0
sbit LCD_RS = P2^6;
sbit LCD_RW = P2^5;
sbit LCD_EN = P2^7;
sbit LCD_CS1 = P1^0;
sbit LCD_CS2 = P1^1;
sbit LCD_RST = P1^2;

unsigned char code logo[1024] = {
  // 这里是校徽的点阵数据，由于篇幅原因，我就不一一列举了
};

void delay_us(unsigned int t) {
  while(t--);
}

void delay_ms(unsigned int t) {
  unsigned int i, j;
  for(i=0; i<t; i++) {
    for(j=0; j<114; j++);
  }
}

void lcd_write_cmd(unsigned char cmd) {
  LCD_RS = 0;
  LCD_RW = 0;
  LCD_EN = 1;
  LCD_PORT = cmd;
  _nop_();
  LCD_EN = 0;
}

void lcd_write_data(unsigned char dat) {
  LCD_RS = 1;
  LCD_RW = 0;
  LCD_EN = 1;
  LCD_PORT = dat;
  _nop_();
  LCD_EN = 0;
}

void lcd_init() {
  LCD_RST = 0;
  delay_ms(20);
  LCD_RST = 1;
  lcd_write_cmd(0x3f);
  lcd_write_cmd(0xc0);
  lcd_write_cmd(0xb8);
  lcd_write_cmd(0x40);
}

void lcd_set_xy(unsigned char x, unsigned char y) {
  if(x < 64) {
    LCD_CS1 = 1;
    LCD_CS2 = 0;
    lcd_write_cmd(0x40 | x);
  } else {
    LCD_CS1 = 0;
    LCD_CS2 = 1;
    lcd_write_cmd(0x40 | (x - 64));
  }
  lcd_write_cmd(0xb8 | y);
}

void lcd_display(unsigned char *dat) {
  unsigned int i;
  for(i=0; i<1024; i++) {
    lcd_write_data(dat[i]);
  }
}

void main() {
  lcd_init();
  lcd_set_xy(0, 0);
  lcd_display(logo);
  while(1);
}

需要注意的是，这段代码中只给出了校徽的点阵数据，并没有包含完整的12864显示屏初始化和显示代码。如果需要完整的代码，可以参考相关的教程和资料。
