#include <SomeLibrary.h> // 确保包含了这个库 void setup() { // 初始化代码 } void loop() { SomeLibraryFunction(); // 如果SomeLibrary.h未包含,这里会报错 } 清理项目并重新编译: 有时,临时文件或旧的编译缓存可能会导致编译错误。你可以尝试在Arduino IDE中清理项
Use the Arduino IDE’s built-in error messages to help locate the problem. Here’s a simple example of a common syntax error and how to correct it: voidsetup(){Serial.begin(9600)}voidloop(){Serial.println("Hello, World!");}
void loop() { if (Firebase.failed()) { Serial.print("setting number failed:"); Serial.println(Firebase.error()); firebasereconnect(); return; } val1=Firebase.getString("S1").toInt(); //Reading the value of the varialble Status from the firebase ...
The nasty error code 5 beat me today, find a cure by adding Serial.prinln(); at the end of void loop(). Nasty error - nasty solution, but i could not leave the things that way, so I spent few hours in investigation of forum. Test the old version of ld.exe from IDE 1.05, OK...
