您好，我正在尝试添加一个简单的代码，但在编辑后无法编译代码。有人可以建议发生了什么事。

@algo1980：Grbl 不使用任何 Arduino 代码，如果您尝试使用，它会中断。它仅使用 IDE 作为编译和刷新它的工具。您将只需要编辑和编写 Grbl 源代码。避免任何 Arduino 函数调用。

感谢您的快速回复。

什么是 IO 异常错误？

那不是编译错误。某些文件无法访问或上传时串口错误。2017-05-17 17:45 GMT-03:00 algo1980 <notifications@github.com>：

我尝试添加 .h 和 .cpp。编译时说无法上传..

怎么了？

无论我在做什么，它都会返回一个错误

@algo1980 no one can assist you if you don’t provide more information on what you’re actually doing. You will need to explain what version of grbl you are using, what version of Arduino, what platform you’re compiling on and the hardware you are targeting. You also need to show some code and provide error messages. Just saying “it could not upload” or “it returns with an error” doesn’t get us anywhere!

using grbl0.9e on atmega 2560. i am trying to add the lcd.cpp and lcd.h to the whole set of grbl files, but it fails to compile it. here is the code im adding
