C51单片机中断定义

C51函数声明对ANSI C作了扩展，具体包括： 1. 中断函数声明：中断声明方法如下： void serial_ISR () interrupt 4 { /* ISR */ } 为提高代码的容错能力，在没用到的中断入口处生成iret语句，定义没用到的中断。 /* define not used interrupt, so generate IRET in their entrance */ void extern0_ISR() interrupt 0{} /* not used */ void timer0_ISR () interrupt 1{} /* not used */ void extern1_ISR()

Keil C51使用教程---C51 vs 标准C（三）

深入理解并应用C51对标准ANSIC的扩展是学习C51的关键之一。因为大多数扩展功能都是直接针对8051系列CPU硬件的。大致有以下8类： ●8051存储类型及存储区域 ●存储模式 ●存储器类型声明 ●变量类型声明 ●位变量与位寻址 ●特殊功能寄存器(SFR) ●C51指针 ●函数属性具体说明如下(8031为缺省CPU)。第一节 Keil C51扩展关键字 C51 V4.0版本有以下扩展关键字(共19个)： _at_ idata sfr16 alien interrupt small bdata large _task_

关于在 KEIL C51 中嵌入汇编以及C51与A51间的相互调用

如何在 KEIL C51（v6.21）中调用汇编函数的一个示例有关c51调用汇编的方法已经有很多帖子讲到，但是一般只讲要点，很少有对整个过程作详细描述，对于初学者是不够的，这里笔者通过一个简单例子对这个过程进行描述，希望能对初学者有所帮助。几年来，在这个论坛里笔者得到很多热心人指导，因此也希望藉此尽一点绵薄之力。在这个例子里，阐述了编写c51程序调用汇编函数的一种方法，这个外部函数的入口参数是一个字符型变量和一个位变量，返回值是一个整型变量。例中，先用c51写出这个函数的主体，然后用SRC控制指令编译产生asm文件，进一步修改这个asm文件就得到我们所要的汇编函数。该方法让编译器自动完成各种段的安排，提高了汇编程序

Keil C51使用教程---开发系统基本知识（一）

Keil C51使用教程---开发系统基本知识（一）第一节系统概述 Keil C51是美国Keil Software公司出品的51系列兼容单片机C语言软件开发系统，与汇编相比，C语言在功能上、结构性、可读性、可维护性上有明显的优势，因而易学易用。用过汇编语言后再使用C来开发，体会更加深刻。 Keil C51软件提供丰富的库函数和功能强大的集成开发调试工具，全Windows界面。另外重要的一点，只要看一下编译后生成的汇编代码，就能体会到Keil C51生成的目标代码效率非常之高，多数语句生成的汇编代码很紧凑，容易理解。在开发大型软件时更能体现高级语言的优势。下面详细介绍Keil C51开发系统各部分功能

c51中定时器工作时如何使用T0脚输入脉冲信号？

嵌入式系统中，定时器是一种常用的设备，可以实现各种时间控制功能，如计时、计数、产生中断等。8051单片机中有两个定时器：T0和T1，其中T0定时器主要用于计时和计数操作，可以通过T0脚输入脉冲信号来控制定时器的工作。 T0脚是单片机的P3.4口，既可以作为普通的输入输出口，也可以作为T0定时器的外部输入引脚。当T0脚作为定时器的外部输入引脚时，可以通过输入的脉冲信号来控制定时器的计数。在使用T0脚输入脉冲信号时，需要采取一些措施来确保信号的稳定性和正确性。首先，需要确定输入脉冲信号的频率。在使用T0脚输入脉冲信号时，需要将信号的频率与定时器的工作频率相匹配。具体来说，当定时器使用外部时钟源时，其工作频率为外部时钟源频率的一半，因
