Arduino的错误：没有指定类型？ [英] Arduino error: does not name a type?
本文介绍了Arduino的错误：没有指定类型？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我写了一个库，但有出错的问题没有指定类型。我tryed一切，搜索了几个小时，没有运气。库放置在Arduino的草图文件夹的库文件夹中。请帮忙！！！我使用OSX，但在Windows出现同样的问题也。
这是库的头文件：
的#ifndef OpticalSensor_h
＃定义OpticalSensor_h＃包括LT＆;＆Arduino.h GT;
＃包括LT＆;＆SD.h GT;
＃包括LT＆;＆Wire.h GT;
＃包括LT＆;＆Adafruit_MCP23017.h GT;
＃包括LT＆;＆Adafruit_RGBLCDShield.h GT;
＃包括LT＆;＆STRING.H GT;类OpticalSensor

上市：

};＃万一
这是图书馆的.cpp文件：

如果（布尔==真）{

}
}双功放＆; ReadFromAnalogPort（）

}
而这正是包括库中的文件.ino：
的#include＆LT; OpticalSensor.h＆GT;OpticalSensor传感器（0）;无效设置（）{
sensor.LCDInit（16,2）;
sensor.SerialInit（9600）;
sensor.SDInit（）;
sensor.SDCreateFile（测试1）;
sensor.SDOpenFileToStream（测试1）;
}空隙环（）{}
这是错误：
在从Test_OpticalSensorLib.ino包含的文件：1：
/Users/gaspersladic/Documents/Arduino/libraries/OpticalSensor/OpticalSensor.h:34：
错误：Adafruit_RGBLCDShield没有指定类型
/Users/gaspersladic/Documents/Arduino/libraries/OpticalSensor/OpticalSensor.h:35：
错误：文件没有指定类型解决方案这两个包含您在您的评论何况是必不可少的。 没有指定类型'只是意味着有该标识的编译器可见没有定义。如果你提到的LCD库有错误，那么这些需要解决的问题！ - 省略的#include肯定不会解决它。
从经验有两点需要注意这可能是有益的：
您需要添加所有＃包括对主要的草图 - 无论他们是否通过其它#include包含
如果您将文件添加到库文件夹，Arduino的IDE之前一定要这些新文件重新启动将是可见的。
I have written a library, but have problem with error does not name a type. I've tryed everything, searched for couple of hours and no luck. Library is placed in the "libraries" folder of the arduino sketch folder. Please help!!! I am using OSX, but the same problem occurs on Windows also.
This is header file of the library:
#ifndef OpticalSensor_h #define OpticalSensor_h #include <Arduino.h> #include <SD.h> #include <Wire.h> #include <Adafruit_MCP23017.h> #include <Adafruit_RGBLCDShield.h> #include <String.h> class OpticalSensor { public: OpticalSensor(int analogPort); void LCDInit(int columns, int rows); void SerialInit(int bitRate); void SDInit(); double& ReadFromAnalogPort(); void SDCreateFile(String fileName); void SDDeleteFile(String fileName); void SDWriteToFile(String fileName); void SDStreamToFile(String Text); void SDOpenFileToStream(String fileName); private: int _analogPort; bool _displayFlag; Adafruit_RGBLCDShield _lcd; File _MainRecFile; double _voltage; void _LCDClearAll(); void _LCDWriteInTwoRows(String row1, String row2); void _DelayAndClearLCD(bool returnStatus); }; #endifThis is .cpp file of the library:
#include <OpticalSensor.h> Adafruit_RGBLCDShield _lcd; File _MainRecFile; double _voltage; OpticalSensor::OpticalSensor(int analogPort) { _analogPort = analogPort; } void OpticalSensor::LCDInit(int columns, int rows) { _lcd = Adafruit_RGBLCDShield(); _lcd.begin(columns,rows); } void OpticalSensor::SerialInit(int bitRate) { Serial.begin(bitRate); _bitRate = bitRate; while(!Serial) { //wait until serial is not open } } void OpticalSensor::SDInit() { // On the Ethernet Shield, CS is pin 4. It's set as an output by default. // Note that even if it's not used as the CS pin, the hardware SS pin // (10 on most Arduino boards, 53 on the Mega) must be left as an output // or the SD library functions will not work. pinMode(10, OUTPUT); //check if SD can be found and initialized. Print also message to //Serial if initialized and to _lcd if initialized. if(!SD.begin(4)) { if(Serial){ Serial.println("Initialization failed!"); } if(_lcd){ _lcd.print("Init failed!"); } _DelayAndClearLCD(true); } else { if(Serial) { Serial.println("Initialization done!"); } if(_lcd) { lcd.print("Init done!"); } _DelayAndClearLCD(false); } } void OpticalSensor::SDCreateFile(String fileName) { //check if file allready exists, if not it creates one //and writes apropriate response to //lcd and Serial if they are initialized. if(SD.exists(fileName)) { if(Serial) { Serial.println(fileName + " already exists!"); } if(_lcd) { _LCDWriteInTwoLines(fileName,"already exists!"); } _DelayAndClearLCD(false); } else { if(Serial) { Serial.println(fileName + "Creating file " + fileName + "..."); } if(_lcd) { _LCDWriteInTwoLines("Creating file", fileName); } _MainRecFile = SD.open(fileName + ".txt", FILE_WRITE); _MainRecFile.close(); _DelayAndClearLCD(false); //check if file was created successffully and print apropriate response //to lcd and Serial if they are initialized if(SD.exists(fileName + ".txt")) { if(Serial) { Serial.println(fileName + ".txt" + " created successffully!"); } if(_lcd) { _LCDWriteInTwoLines(fileName + ".txt", "created!"); } _DelayAndClearLCD(false); } else { if(Serial) { Serial.println("error: failed to create file!"); } if(_lcd) { _LCDWriteInTwoLines("error: failed to","create file!"); } _DelayAndClearLCD(false); } } } //delete file from SD card void OpticalSensor::SDDeleteFile(String fileName) { } //open file, write data to it, and close file after. void OpticalSensor::SDWriteToFile(String fileName, String Text) { _MainRecFile = SD.open(fileName + ".txt", FILE_WRITE); _MainRecFile.println(Text); _MainRecFile.close(); } //Open file to stream data to it. void OpticalSensor::SDOpenFileToStream(String fileName) { _MainRecFile = SD.open(fileName + ".txt", FILE_WRITE); } //Write data to file while file is open. //Notice that you can stream data only to one file at a time!!! //For instance, if you have two sensors that you want to //write data to two different files, you have to use SDWriteToFile //function!!! void OpticalSensor::SDStreamToFile(String Text) { if(_MainRecFile) { _MainRecFile.println(Text); } } //close file that you streamed data too. void OpticalSensor::SDCloseStreaming(String fileName) { _MainRecFile.close(); } //clear entire LCD void OpticalSensor::_LCDClearAll() { _lcd.clear(); _lcd.setCursor(0,0); } void OpticalSensor::_LCDWriteInTwoRows(String row1, String row2) { //write first String in row1 _lcd.print(row1); //set cursor to the beginning of row 2 _lcd.setCursor(0,1); //write second String to row 2 _lcd.print(row2); } void OpticalSensor::_DelayAndClearLCD(bool returnStatus) { //if Serial or _lcd are initialized, delay for 2 seconds //and clear LCD if(Serial || _lcd) { delay(2000); if(_lcd) _LCDClearAll(); } //terminate if(bool == true) { return; } } double& ReadFromAnalogPort() { _voltage = analogRead(_analogPort); return _voltage; }And this is the .ino file where library is included:
#include <OpticalSensor.h> OpticalSensor sensor(0); void setup() { sensor.LCDInit(16,2); sensor.SerialInit(9600); sensor.SDInit(); sensor.SDCreateFile("test1"); sensor.SDOpenFileToStream("test1"); } void loop() { }this is the error:
In file included from Test_OpticalSensorLib.ino:1: /Users/gaspersladic/Documents/Arduino/libraries/OpticalSensor/OpticalSensor.h:34: error: 'Adafruit_RGBLCDShield' does not name a type /Users/gaspersladic/Documents/Arduino/libraries/OpticalSensor/OpticalSensor.h:35: error: 'File' does not name a type
解决方案The two includes you mention in your comment are essential. 'does not name a type' just means there is no definition for that identifier visible to the compiler. If there are errors in the LCD library you mention, then those need to be addressed - omitting the #include will definitely not fix it!
Two notes from experience which might be helpful:
You need to add all #include's to the main sketch - irrespective of whether they are included via another #include.
If you add files to the library folder, the Arduino IDE must be restarted before those new files will be visible.
