keil c51怎么生成hex文件

一、Keil C51生成hex文件全攻略

1、Keil C51简介

Keil C51是一款专门为8051微控制器开发的环境，它提供了强大的编译器、调试器和仿真器等功能，使得开发人员能够高效地开发80551系列微控制器应用。在Keil C51中，生成hex文件是编译程序后的一个重要步骤，hex文件可以被烧录到微控制器中，从而实现程序运行。

2、Keil C51生成hex文件步骤

  1. 打开Keil C51，创建一个新的工程或打开一个现有的工程。

  2. 在工程中添加源文件，编译工程。编译成功后，在编译窗口会显示生成的hex文件路径。

  3. 点击菜单栏中的“Project”菜单，选择“Options for Target...”，弹出“Options for Target”对话框。

  4. 在“Output”选项卡中，找到“Output Options”部分，勾选“Create HEX File”选项。

  5. 点击“OK”按钮，关闭对话框。此时，编译后的hex文件将会生成。

3、Keil C51生成hex文件注意事项

  1. 确保工程中的源文件全部编译成功，否则生成的hex文件可能不完整。

  2. 在“Options for Target”对话框中，可以设置hex文件的格式。常用的格式有Intel HEX和S-Record两种。

  3. 如果需要生成烧录到微控制器中的文件，可以选择生成S-Record格式的hex文件。S-Record格式支持烧录文件中的空白区域，适用于一些特殊的应用。

4、Keil C51生成hex文件应用实例

以下是一个简单的示例，演示如何生成Keil C51的hex文件。

  1. 创建一个名为“HelloWorld.c”的源文件，并编写以下代码：

c

include <reg51.h>

void main() { while (1) { P1 = 0xFF; // 打开所有LED灯 delay(500); // 延时500ms P1 = 0x00; // 关闭所有LED灯 delay(500); // 延时500ms } }

void delay(unsigned int ms) { unsigned int i, j; for (i = ms; i > 0; i--) for (j = 110; j > 0; j--); }

  1. 将“HelloWorld.c”文件添加到Keil C51工程中，编译工程。

  2. 在编译窗口中，可以看到生成的hex文件路径。打开该文件，可以看到以下内容：
