附件是ACLLib的全部文件,包括源代码和文档及例子程序.zip
基于您的需求,下面提供了一个完整的示例,该示例涵盖了您提到的要求,并且包含了必要的`keypad.c`, `keypad.h`, `display.c`, 和相应的头文件定义:
### keypad.h
```c
#ifndef KEYPAD_H_
#define KEYPAD_H_
#include "reg52.h"
extern unsigned char keyscan();
extern bit KeyPressed(unsigned char keynum);
#define ROWS 4
#define COLS 3
unsigned char rowpins[ROWS] = {P2_0, P2_1, P2_2, P2_3};
unsigned char colpins[COLS] = {P2_4, P2_5, P2_6};
#endif /* KEYPAD_H_ */
```
### keypad.c
```c
#include "keypad.h"
#include "delay.h" // 假设有一个用于延时的库文件 delay.h
#include <intrins.h> // 提供对内嵌汇编的支持
bit isKeyPressed;
unsigned char keyscan()
{
unsigned char i, j;
unsigned char result = 0xFF; // 所有行都未被按下标志
for(j = 0; j < COLS; j++) {
P2 &= ~(1<<colpins[j]); // 设置当前列为低电平
_nop_();
_nop_();
for(i = 0; i < ROWS; i++) {
if(P2 & (1<<rowpins[i])) { // 如果某一行没有检测到低电平,则说明其上有按键被按下
result = (result & 0xF0) | (i+1);
break;
}
}
P2 |= (1<<colpins[j]); // 恢复原状态
}
return result;
}
bit KeyPressed(unsigned char keynum)
{
if(keynum == keyscan()) {
delayms(20); // 消抖动处理
return (keyscan() == keynum);
} else {
return 0;
}
}
```
### display.h
```c
#ifndef DISPLAY_H_
#define DISPLAY_H_
#include "reg52.h"
void Timer1_init(void);
void dis(void);
#define FOSC 12000000L
#define Timer1_Reload (FOSC / 50)
#endif /* DISPLAY_H_ */
```
### display.c
```c
#include "display.h"
#include "keypad.h"
sbit P1 = P1^0;
sbit c1 = P0^0;
sbit c2 = P0^1;
sbit c3 = P0^2;
sbit dp2 = P1^4;
sbit dp1 = P1^4;
sbit dp0 = P1^4;
unsigned int disd;
u16 digcode[] = {0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};
void dis(void)
{
u8 d2, d1, d0;
d2 = (u8)(disd / 100);
d1 = (u8)(disd / 10 % 10);
d0 = (u8)(disd % 10);
P1 = digcode[d2];
if(dp2) P1 |= 0x10;
c1 = 0; c2 = 1; c3 = 1;
delay100us(30);
P1 = digcode[d1];
if(dp1) P1 |= 0x10;
c1 = 1; c2 = 0; c3 = 1;
delay100us(30);
P1 = digcode[d0];
if(dp0) P1 |= 0x10;
c1 = 1; c2 = 1; c3 = 0;
delay100us(1);
}
void Timer1_init(void)
{
TR1 = 0; // stop counting
ET1 = 1; // enable interrupt
TMOD &= ~0x30;
TMOD |= (0 << 4); // work mode
TH1 = (u8)((65536UL - Timer1_Reload) / 256);
TL1 = (u8)((65536UL - Timer1_Reload) % 256);
TR1 = 1; // start running
}
```
注意以上代码仅为简化版示例,并非完整可直接运行代码。实际开发环境中还需考虑硬件配置及具体细节调整。由于篇幅限制无法完全展开每个功能的具体实现逻辑如具体的延时函数、中断服务函数等,故请结合实际情况完成整个项目的设计。
