我想使用IRremote库制作一个程序，该库使用rawlen对象的decode_results属性获取信号的长度以及5v / 0v信号的长度
目标是打印rawbuf值是串行监视器。
这是整个代码：
#include <IRremote.h>
int IRpin = 11;
IRrecv irrecv(IRpin);
decode_results results;
void setup() {
Serial.begin(9600);
irrecv.enableIRIn();
}
void dump(decode_results *results) {
int count = results->rawlen;
Serial.println("Signal recu !");
Serial.print("Longueur du signal (");
Serial.print(count, DEC);
Serial.println("):");
for(int i = 0; i < count; i++) {
if((i%2) == 1) {
Serial.println(results->rawbuf[i]*USECPERTICK, DEC);
}
else {
Serial.println(-(int)results->rawbuf[i]*USECPERTICK, DEC);
}
}
}
void loop() {
if(irrecv.decode(&results)) {
dump(&results);
irrecv.resume();
}
}
当我运行它时，我会在编译器中得到它：

你知道是什么问题吗？
