MasterErik: have you downloaded and installed the Adafruit_GFX library in addition to Adafruit_LEDBackpack?
If not, you can fetch that here: https://github.com/adafruit/Adafruit-GFX-Library
If yes, and if you're still encountering these error messages, delete (or archive) the Robot_Control library, located here:
C:\Program Files\Arduino\libraries\Robot_Control

Re: Problem compiling example 8x8 LED matrix backpack sketch
Hello, I got the HT16K33 breakout kit and tried to compile it with the libraries Adafruit_GFX and Adafruit_LEDBackpack. I downloaded the libraries today (2014-10-13).
When I try to run Example -> Adafruit_LEDBackpack -> HT16K33, I get the same errors as the thread starter:
no matching function for call to 'Adafruit_GFX::Adafruit_GFX(int, int).
Is the library broken again?
Thanks, Kosmas

Hello, I got it working! It was the problem with Arduino 1.0.5 - I just deleted Robot_Control in the library and now it works! :-)

Re: Problem compiling example 8x8 LED matrix backpack sketch
Same problem... Win7, both libraries are installed (correctly, in documents/arduino/libraries/), and renamed as readme.txt file explains.
I tried to delete both Robot_Control and Robot_Motor in programs(x86)/arduino/libraries.
I have installed both Arduino IDE 1.0.5 and 1.5.5, and example codes work with none...
And further suggestion?
I have many libraries installed (Adafruit GPS, NeoPixel, TinkerKit, DHT22, AndroidAccessory and a couple I've written by myself). Could any of those interfere?

Hi,
just look in your library directories whether there are another versions of the file "Adafruit_GFX.h". If so, try to delete or remove the directories.

Re: Problem compiling example 8x8 LED matrix backpack sketch
This is a conflict between the current Adafruit_GFX library and the one that comes with the Arduino IDE. If you have the current Adafruit_GFX installed in your libraries directory, it will supersede the one that comes with the IDE
