Intel hex 文件常用来保存单片机或其他处理器的目标程序代码。它保存物理程序存储区中的目标代码映象。一般的编程器都支持这种格式。 Intel hex 文件全部由可打印的ASCII字符组成（可以用记事本打开），如下例所示： :2000000012014c75a800e4f508f509780a7a78e4f608dafcd283fcfded240af9a7050dbd81 :2000200000010ced2488ec34ff50edc283e4fcfded240af9e76d7013ed33e43c700d0dbd2a :2000400000010ced2488ec34ff50e50509e50970020508e50924a8e50834fd50aee4f50874 Intel hex 由一条或多条记录组成，每条记录都由一个冒号“:”打头，其格式如下： :CCAAAARR...ZZ 其中: CC 本条记录中的数据字节数 AAAA 本条记录中的数据在存储区中的起始地址 RR 记录类型： 00 数据记录 (data record) 01 结束记录 (end record) 02 段记录 (paragraph record) 03 转移地址记录 (transfer address record) ... 数据域 ZZ 数据域校验和 Intel hex文件记录中的数字都是16进制格式，两个16进制数字代表一个字节。CC域是数据域中的实际字节数，地址、记录类型和校验和域没有计算在内。校验和是取记录中从数据字节计数域(CC)到数据域(...)最后一个字节的所有字节总和的2的补码。 ---------------------------------------------------------------------------- // 这是用C做的 生成HEX文件的程序/这是个正弦ROM表生成程序。直接在VC里运行。 #include<stdlib.h>#include<stdio.h>#include<math.h>#define PI 3.1415926 void main(void){ signed char W_R=0;
