Hi, one other quick issue #27

Closed Sorin-Jayaweera closed 2 years ago

Sorin-Jayaweera commented 2 years ago

--I don't know where a forum to ask this is, but if you want me to move this there I can --

Hi, I'm using a library called the "Adafruit_PWMServoDriver" In both the .cpp and .h of the library, I changed the includes to (cpp) Origional:

include "Adafruit_PWMServoDriver.h"

include

New:

include "Adafruit_PWMServoDriver.h"

include "i2c_driver_wire.h"

(.h) Origional:

include

include

New:

include "Arduino.h"

include "i2c_driver_wire.h"

However, when I try to build the code, I get the error message Adafruit_PWMServoDriver.cpp.o: In function `Adafruit_PWMServoDriver::Adafruit_PWMServoDriver()':

Adafruit_PWMServoDriver.cpp:40: multiple definition of `Adafruit_PWMServoDriver::Adafruit_PWMServoDriver()' (Deleted the unnessisry filepath lines)

I tried putting "#pragma once" at the top of the .h, but i got the same error. What should I do / what am I doing wrong?

Thank you Mr. Gemmell!

Just in case, the full error message

turns out it is an issue with the library itself, your code is perfect. Sorry for the worry!

Richard-Gemmell commented 2 years ago

No worries. Thanks for letting me know.
