T2 要大改，设置方式什么的都不一样了， T0,T1 改动不大，不要去动AUXR, TMOD = 0x00, 16位自动重载，中断中不用再重新赋值 TH0,TL0 会自动下一轮计数。其他没什么变化。

为何不查看一下两者的手册呢？这样才能学到东西，也提升解决问题的能力。

如果晶振频率一样的话，定时器相关的可以不需要改

我看了啊，我就是对比之后弄不出来

稍微，花了点力气看了一下你这代码……，
你这写的啥？？
不会是用定时器作蜂鸣器奏乐吧？希望我猜错。

从代码上看，能正常跑，唯一就是 P1, 你设置的准双向， P16 = 1 的时候，输出可能不够。
TMOD = 0x11; 如果你是 STC8 的话 T1,T0 不会自动重载, 全靠T1中断里面的赋值。
需要注意的是：
你T1 中断里面用了，uchar aa,bb；这种情况一般，需要指定寄存器组，比如：
Timer1() interrupt 3 using 1
不然，每次进入中断，可能会 aa,bb 不是你以为的值。
