装了SDCC，CodeBlocks，新建一个小工程，编译无问题，运行却不正确
源码在下面，就是让两个LED闪烁。附件中包括了源码，工程文件以及各Proteus模型。 点击此处下载 ourdev_606101LQ7SM4.rar(文件大小:19K) (原文件名:sbittst.rar)
另外顺便问一下，网上老邓的CodeBlocks便携版，Cscope怎么用？

LED01 ^= 1;
LEDFlash ^= 1;
timer0_update();
}
}
}
void timer0_init(void)
{
TMOD &= 0xF0;
TMOD |= 0x01;
TF0= 1;
TR0= 1;
}
void timer0_update(void)
{
TF0= 0;
TL0= 0x00;
TH0= 0xC0;
} 开源的SDCC没用过，知道的来指点下 从Proteus运行状况来看，TMOD没有赋值，运行中TH、TL不变化 void main(void)
{
LED01 = 0;
LEDFlash = 1;
timer0_update(); //这个要改成timer0_init() 吧?
while(1) 谢谢Shark
搞定 继续请教
网上老邓的CodeBlocks便携版，Cscope怎么用？ 怎么用都没什么反应哦
我希望像Source Insight类似，选中一个标识符，可以看见定义什么的。 zieous 发表于 2010-12-21 20:36

请教楼主，CodeBlocks中使用SDCC编译楼主的代码，无法生成目标文件 ihx。编译结果如下：没有错误和警告，最后两行是红色的是怎么回事？
