通过串口调试助手输入脉冲宽度，控制单片机输出脉冲，程序清单如下，求改正
#include<reg52.h>
sbit P10=P1^0;
void delay(unsigned int n)
{
TH0=(65536-n)/256;
TL0=(65536-n)%256;
TR0=1;
while(TF0==0)
;
TF0=0;
TR0=0;
}
unsigned char receive(void)
{unsigned char dat;
while(RI==0)
;
RI=0;
dat=SBUF/(0.6);
return dat;
}
void main (void)
{TMOD=0x20;
SCON=0x50;
PCON=0x00;
TH1=0xfd;
TL1=0xfd;
TR1=1;
REN=1;
while(1)
{
P10=0;
delay(receive);
P10=1;
delay(receive);
}}
不知道哪里有错误  谢谢大虾了
