Error compiling Adafruit_22d1306 example [SOLVED]

bananazx · August 20, 2014, 6:20pm

I got my sparkcore expecting the usage would be the same as arduino.
From the beginning I have had hard time using this.
Simple example like blinking led works fine but when I tried to use one of the examples which is included in the libraries on WEB IDE, it gives me error message.

ssd1306-128x64-i2c.ino

I tried to compile this and the error message shows that it could not find Adafruit_GFX.h.

Therefore, I manually copy and pasted .h and .c to my sketch.

But it still doesn’t work.

error message

What am I doing wrong?

Another question is, what most people do when you program sparkcore, WEB IDE or local compile? In other word, what’s the easiest and best way to program this thing?

Hello @bananazx

Sorry to hear you’re having trouble. The libraries are not maintained by spark, so it’s best to contact the library author about any troubles you are having. (All libraries are hosted in github, so you can create an issue there to alert the library author to your problem.)

But you’re in luck! It looks like in this case it’s just a problem with the example code included with the library. After clicking “USE THIS EXAMPLE”, change this code at the top of the file:

#include "Adafruit_GFX.h"
#include "Adafruit_SSD1306.h"

into

#include "Adafruit_SSD1306/Adafruit_GFX.h"
#include "Adafruit_SSD1306/Adafruit_SSD1306.h"

and the code should compile fine!

As to local or online development, starting with the online IDE is simplest - it’s as close to plug and play as you can get!

Oh! It compiles like a charm. I will keep using online IDE. Thank you very much mdma. I really appreciate.

Hi all,

Not sure what I am doing wrong here. Same issue as above BUT still a problem despite using the new include statements as above:

Hope someone can assist.
many thanks if you can.
Steve

There’s no error in the text you pasted?

Hi! I get the same error… did you find the problem? Thx!

jcarre · October 10, 2014, 4:56pm

ok forget me… I just renamed the random routine to random2 in .ino file…
