Arduino Error Compiling Does Not Name A Type
Sep 22, 2009, 08:02 pm by udokleinReason: 1 Today I tried to split my current project into some libraries. I did this according to the tutorial in the playground. It works fine as long as I do not define any variables in the .h files.For arduino error compiling blink example I have put my LCD handling into a separate .h and .cpp file like so:Code: [Select] here for error compiling arduino uno a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or http://forum.arduino.cc/index.php?topic=47992.0 posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other.

I am trying to test it using the sketch motordrivertest.ino, and I keep on getting a multiple definition error of my whole motor class and all of its methods. I am wondering how I can fix these errors. (I am using MAC OS X 10.9.3) Here is my error. MotorDriver/motordriver.cpp.o: In function `Motor::getSpeed()': /Users/pattyborgman/Documents/Arduino/libraries/MotorDriver/motordriver.cpp:49: multiple definition of `Motor::getSpeed()' motordrivertest.cpp.o:/Users/pattyborgman/Documents/Arduino/libraries/MotorDriver/motordriver.cpp:49: first defined here MotorDriver/motordriver.cpp.o: In function `Motor::setSpeed(int)': /Users/pattyborgman/Documents/Arduino/libraries/MotorDriver/motordriver.cpp:33: multiple definition of `Motor::setSpeed(int)' motordrivertest.cpp.o:/Users/pattyborgman/Documents/Arduino/libraries/MotorDriver/motordriver.cpp:33: first defined here MotorDriver/motordriver.cpp.o: In function `Motor': /Users/pattyborgman/Documents/Arduino/libraries/MotorDriver/motordriver.cpp:15: multiple definition of `Motor::Motor(char)' motordrivertest.cpp.o:/Users/pattyborgman/Documents/Arduino/libraries/MotorDriver/motordriver.cpp:15: first defined here MotorDriver/motordriver.cpp.o: In function `Motor': /Users/pattyborgma a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us http://arduino.stackexchange.com/questions/3061/error-compiling Learn more about Stack Overflow the company Business Learn more about hiring http://www.cplusplus.com/forum/beginner/139036/ developers or posting ads with us Arduino beta Questions Tags Users Badges Unanswered Ask Question _ Arduino Stack Exchange is a question and answer site for developers of open-source hardware and software that is compatible with Arduino.

I guess because I use functions within other functions in the same class. How do I get around this please? Display.ino 1
#ifndef UT_LCD_h
#define UT_LCD_h
#include
#include
//create object to control void menu__init() an LCD, number of lines in display=2
//LCD4Bit_mod lcd = LCD4Bit_mod(2);
LiquidCrystal lcd(10, 11, 9, 4, 5, 6, 7);
// function definitions follow here
#endif
The cpp file includes it withCode: [Select]
#include "UT_LCD.h"
and the main file includes them with Code: [Select]
#include
When I try to compile this I always get an errorCode: [Select]
