13:32:59.249 -> The function decode(&results)) is deprecated and may not work as expected! Just use decode() without a parameter and IrReceiver.decodedIRData.<fieldname> .
啥意思？？？？

5. const int rightPin4=5;  //BIN2连接引脚3
   
6. const int irPin = A0;  //红外遥控传感器信号引脚连接主板引脚A0
   
7. const int maxspeedPwm = 255;  //PWM 最大值
   
8. const int minspeedPwm = 90;  //PWM 最小值

求您了，大佬！！！！

函数 decode（&results）） 已弃用，可能无法按预期工作！只需使用不带参数的decode（）和IrReceiver.decodedIRData。<fieldname> 。
