IQmath.h的问题

只看该作者 · 2009-8-25 09:26

code composer could not locate IQNsqrt.asm
would you like to browse for it?

这是我在运行IQmath库时
老是出现这个框
下面是主程序
#include "IQmathLib.h"

#define PI 3.1415926
//----------------------------------------------------------------------------
// Main code:
//----------------------------------------------------------------------------
_iq in1,out1;

int main(void)
{
in1=_IQ(0.25*PI);
out1=_IQsqrt(in1);

}

大家知道是什么原因吗？

英文提示不是告诉你原因了撒，我个人猜测是缺少IQ的库吧，或者是IQNsqrt.asm文件没加到工程里来！

在main函数中加“IQmathLib。h”，在cmd文件分配空间，还需要在哪里加文件呀？

IQmathLib。h
只是Q格式的头文件而已，而如果你程序调用比如SIN COS的Q格式运算，就需要调用LIB 注意 LIB跟H文件不是同一个概念，
或者这样说 IQmath,LIB只需要添加到工程中，而不需要额外的代码包含它！
这是我的理解

不是很理解，你能说的具体点吗？

用IQmath首先要安装，装完了之后在project里添加IQmath.lib，然后在程序里添加#include "IQmathLib.h"，链接汇编一下就会自动生成.h文件，最后修改cmd文件如下：

我是这样做的，算的挺好的，楼主试一试。
