在 Uno r4 wifi 上运行代码时出错，但在 Nano 上运行良好

问题描述 投票：0回答：1

我有一些代码，可以用来通过 arduino nano 和 IR LED 关闭和打开电视。效果很好。但是，我想在 uno r4 wifi 上运行它，以便可以远程控制它。当我将相同的代码上传到 uno r4 时，我收到此错误：（我将其放在一个块中，这样阅读起来就不那么糟糕了。

这是我上传的代码：

#include <IRremote.h>

int LED = 13;
IRsend irsend;

void setup() {
    pinMode(LED, OUTPUT); 
    pinMode(7,INPUT_PULLUP); 
}

void loop() {  
    if (digitalRead(7) == HIGH){
        digitalWrite(LED, HIGH);
        for (int i = 0; i < 3; i++) {
            irsend.sendSony(0xa90, 12); // 12 bit wide Sony TV power code
            delay(40);
        }
     } 
     else digitalWrite(LED, LOW);
     
     delay(100);  
}

有谁知道为什么代码在 nano 上运行良好但在上传到 uno r4 时出现此错误？非常感谢。

IRremote 库应该与 Uno R4 完全兼容，您可能拥有旧版本或与 https://www.arduino.cc/reference/en/libraries/irremote/

中列出的版本不同的版本

我通过选择 Uno R4 Minima 尝试了你的代码，只需要安装 IRremote 库（在“Sketch”->“添加库”->“管理库”（或 CTRL+SHIFT+I）中，然后输入“irremote”）搜索并安装）。

Using library IRremote at version 4.3.0 in folder: C:\Users\m\Documents\Arduino\libraries\IRremote
