单片机程序空间不足救急 [复制链接]

芯片型号:HT48F10E,已经定死的
功能描述:负离子热吹风机,主要在温度控制.传感器是热敏电阻,构成RC震荡电路,测充放电时间,电源有2个规格,50HZ和60HZ.
ROM大小:1K(1024BYTE)
问题描述:程序还有少量没完成,但快超出ROM边界.(合泰的编译器效率比较低)
希望通过代码优化,改善算发,将公共代码做成子函数调用等来解决.或者按程序功能,改成汇编,以节约ROM空间,谢谢,下面系代码:源代码能编译通过.

这个简单，你编译出来是HEX文件的吧，那是十六进制文件，然后你有HEX转BIN文件就可以了，一般情况下，40K的HEX文件可以转成20多K的BIN文件

还有一种方法，就是将C改为汇编，那样编译出来就小多了

不是HEX文件,是MTP的哦,见下面

void freq_detect( void )
{
unsigned char temp00;
temp00=zero_pos;
while (temp00==zero_pos);
_tmrc=0x10;
while (temp00!=zero_pos);
while (temp00==zero_pos);
frequency=_tmr;
}
这里不知能不能精简一点。

不要什么都找人帮忙,还是要靠自己啊.
