本屌做的atmega128下的avr密码锁实验，这段key的代码返回时出现错误，求解
//-----------------------------------------------------------------// 名称: 键盘矩阵扫描程序
//-----------------------------------------------------------------
#include <iom128v.h>
#include <macros.h>
#define INT8U unsigned char
#define INT16U unsigned int
//当前按键序号,该矩阵中序号范围为0-15,0xFF表示无按键
INT8U KeyNo = 0xFF ;
//-----------------------------------------------------------------
// 判断键盘矩阵是否有键按下
//-----------------------------------------------------------------
INT8U KeyMatrix_Down()
{
DDRE = 0xf0;
PORTE = 0x0f;
delay_ms(1);
return PINE !=0x0f 1:0;
}
//-----------------------------------------------------------------
// 键盘矩阵扫描子程序
//-----------------------------------------------------------------
void Keys_Scan()
{
}
