標題: 運行錯誤單片機步進電機模塊正轉,反轉調速Proteus仿真+程序
步進電機模塊，正轉，反轉調速
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）

單片機源程序如下:
/*---------------------------------------------------------------------
                     LCD1602.C文件 LCD1602的函數
----------------------------------------------------------------------*/

#include "hardware.h"
#include "lcd1602.h"

void LCD_check_busy(void) //檢測LCD狀態，看它是不是還在忙呢
{
while(1)
  {
LCD_EN=0;
LCD_RS=0;
LCD_RW=1;
LCD_DATA=0xff;
LCD_EN=1;
if(!LCD_BUSY)break;
  }
LCD_EN=0;
}

void LCD_cls(void)       //LCD清屏
{

LCD_check_busy();
LCD_RS=0;
LCD_RW=0;
LCD_DATA=1;
LCD_EN=1;
LCD_EN=0;

}

void LCD_write_instruction(unsigned char LCD_instruction) //寫指令到LCD
{
  LCD_check_busy();
LCD_RS=0;
LCD_RW=0;

LCD_DATA=LCD_instruction;
LCD_EN=1;
LCD_EN=0;
}

void LCD_write_data(unsigned char LCD_data)    //輸出一個字節數據到LCD
{
  LCD_check_busy();
LCD_RS=1;
LCD_RW=0;

LCD_DATA=LCD_data;
LCD_EN=1;
LCD_EN=0;
}

void LCD_set_position(unsigned char x)          //LCD光標定位到x處
{
LCD_write_instruction(0x80+x);
}

/*
void LCD_go_home(void)                      //LCD光標歸位
{
LCD_write_instruction(LCD_GO_HOME);
}
*/

void LCD_printc(unsigned char lcd_data)       //輸出一個字符到LCD
{
LCD_write_data(lcd_data);
}

void LCD_prints(unsigned char *lcd_string)    //輸出一個字符串到LCD
{
unsigned char i=0;
while(lcd_string[ i]!=0x00)
  {
LCD_write_data(lcd_string[ i]);
i++;
  }
}

void LCD_initial(void)                      //初始化LCD
{
LCD_write_instruction(LCD_AC_AUTO_INCREMENT|LCD_MOVE_DISENABLE);
LCD_write_instruction(LCD_DISPLAY_ON|LCD_CURSOR_OFF);
LCD_write_instruction(LCD_DISPLAY_DOUBLE_LINE);
LCD_cls();
}

仿真圖沒有Lcd1602，程序里面怎么有Lcd1602的程序呢？
