Adafruit SSD1331 OLED Driver Library for Spark?

huxlot · November 9, 2014, 3:09pm

Hi,

I’m trying to get this display (https://learn.adafruit.com/096-mini-color-oled/overview) to work on spark. Has somebody made this work so far and happens to have the library for me?

Thanks,

@huxlot I may be able to port this library for later today.

peekay123 · November 10, 2014, 2:49am

@huxlot, I posted the updated library on my github here. The test program is set to use the hardware SPI configuration. Let me know how it goes!

huxlot · November 10, 2014, 7:27am

@peekay123 You are the best! I’ll update as soon as the parts arrive and I’m able to try it!

Hi again,

I tried to compile the test.ino from your library, but I’m running into an error.
As you will see, I have no idea what I’m doing. Therefore I’m assuming that I’m doing some fundamental mistakes.

What I have done is:

added new .cpp/.h files to my app
copied the corresponding code from your library
copied the code from the test.ino (with automatically added #include “Adafruit_SSD1331.h” at the top)
compiled

and the error:

Adafruit_SSD1331.cpp:14:26: fatal error: Adafruit_GFX.h: No such file or directory
#include "Adafruit_GFX.h" 
^
compilation terminated.
make: *** [Adafruit_SSD1331.o] Error 1

After the first error I tried adding the Adafruit_GFX library to the app, but received this (basically the same thing?):

In file included from ../inc/spark_wiring.h:29:0,
from ../inc/application.h:29,
from Adafruit_GFX/Adafruit_GFX.h:4,

Any help would be greatly appreciated.

@huxlot, try changing the #include line in Adafruit_SSD1331.cpp to:

#include Adafruit_GFX/Adafruit_GFX.h

The path “issues” when using IDE libraries is part of the reason I use Spark CLI and Spark DEV. Let me know how it goes.

huxlot · December 4, 2014, 10:02am

I appreciate your help a lot!

Using the line you suggested worked for the path error, and there was another one for glcdfont.c. I included the glcdfont files from your github (https://github.com/pkourany/Adafruit_SharpMem) and the path “issues” seem to be fixed.

Another day, another error:

Thanks for looking into this!

peekay123 · December 4, 2014, 2:25pm

@huxlot, there was a missing definition for _BV() in Adafruit_SSD1331.h so I fixed it. Get the file from my repo again.

Hi peekay,

I still have trouble compiling + I don’t understand the error message:

Ready.

Any Ideas?

peekay123 · December 12, 2014, 1:33pm

@huxlot, can you post the code for actualtest.cpp? From the looks of it, I guess you are compiling on the web IDE. You may want to change your #include in actualtest.cpp to:

#include "Adafruit_GFX/Adafruit_GFX.h"

huxlot · January 2, 2015, 9:31am

My apologies for the late repsonse, Yes, I’m compiling on the web IDE.

Here’s the actualtest.ino

// This #include statement was automatically added by the Spark IDE.
#include "glcdfont.h"

// This #include statement was automatically added by the Spark IDE.

It only contains the headers and the code from your libraries test.ino. As you see, I changed the Adafruit_GFX.h to

#include "Adafruit_GFX/Adafruit_GFX.h"

in the actualtest.ino. Also, as mentioned earlier in this thread. I changed the Adafruit_GFX header in the Adafruit_SSD1331.cpp file.

Thank you for your effort.

ScruffR · January 2, 2015, 10:00am

To give Paul (aka @peekay123) some slack, I try to chime in here
If I look at your code, I can see two #includes for Adafruit_GFX, the one at the top, added by the Web IDE and a bit further down here

...
#if defined (SPARK)
#include "Adafruit_GFX.h"
#include "Adafruit_SSD1331.h"
#else
#include <Adafruit_GFX.h>
#include <Adafruit_SSD1331.h>
#include <SPI.h>
#endif
...

I think you can either comment this one or the one above out, and/or you convert this one the same way as above, since double include is prevented inside the header anyway.

peekay123 · January 2, 2015, 1:51pm

Thanks @ScruffR! You are correct, the top 3 includes inserted by the IDE can be commented out,
