問題是 用keil開始仿真就發聲，然后鍵盤控制不了
void Timer1_Init(void) //10??@12.000MHz
{
AUXR &= 0xBF; //?????12T??
TMOD &= 0x0F; //???????
TL1 = 0xF0; //???????
TH1 = 0xD8; //???????
TF1 = 0; //??TF1??
TR1 = 1; //???1????
}
u8 count,j,key;
void main()
{ P3M0 = 0x80;
P3M1 = 0x00;
Timer1_Init();
IE=0x85;
IT0=1;
IT1=1;
j=4;
if(TF1)
{
TF1=0;
P1=~(1<<j);
j++;
if(j>7)
j=4;
}
if((P1&0x0f)!=0x0f)
{ key=P1;
switch(key)
