请大神帮看一看，这段代码是蓝牙的串口通信中断，Nixie是数码管显示函数，数码管只有在手机点击发送指令时显示1s左右然后就不显示了，想让它一直显示怎么修改void UART_Routine() interrupt 4
{ if (RI)
{
RI = 0;
x = SBUF;
switch (x) {
case 0x01: Compare = 0,Speed=0; ; break;
case 0x02: Compare = 50,Speed=1; break;
case 0x03: Compare = 75,Speed=2; break;
case 0x04: Compare = 100,Speed=3; break;
}
Nixie(1, Speed);
}
}
