本人用到是飛凌(feeling)的FM8PE531MA，程序再換頁的時(shí)候總是有一些問題，程序如下
void chang_pwm(u8 dt) @0x0400
{
if(i<=0)
j=1;
if(i>=60)
j=-1;
if(udata1)
{
udata1=0;
i=i+j;
}
switch(10-dt)
{
case 1:dat9=i;/*dat8=i;dat7=i;dat6=i;dat5=i;dat4=i;dat3=i;dat2=i;dat1=i;*/break;
case 2:dat8=i;/*dat9=0;dat7=i;dat6=i;dat5=i;dat4=i;dat3=i;dat2=i;dat1=i;*/break;
case 3:dat9=0;dat8=0;dat7=i;dat6=i;dat5=i;dat4=i;dat3=i;dat2=i;dat1=i;break;

}
sta我在另一個(gè)函數(shù)里會自加，現(xiàn)在的情況是程序運(yùn)行到case 22那里以后好像就下不去，了，又重case 1開始
