楼上， win7 x86是可以的亲测 这个对坐pwm  dac非常有用的啊！

用 vc 在windows下写一个就是了.

        int i;
        int val;

        printf("const u16 CosVal[360] = {\n");
        for(i=0;i<360;i++)
        {
                val=(int)(cos((double)3.1415927*i/180)*2048 + 2048);
                if(val==4096)
                        val=4095;
                printf("%4d , ",val);
                if(((i+1)%8)==0)
                        printf("  //(%d-%d)\n",i-7,i);
        }
        printf("}\n");

使用就是 xx >> pwm.c 就可以了(xx就是编译后的exe文件名)

都是用Matlab出。
其实excel也能出。

x86的才可以
建议你用 huatong  的自己编译一下再用。

nice!
