The pins are normally held a HIGH by the activated internal pull-up resistors and forced to low via the ground pin by the encoder resp. switch. So you can check the voltage on the signal pins, they should be at 3.3V when the encoder is not connected and either 0V or 3.3V when the encoder is connected, depending on the state it is in.

I have no experience neither with the ramps-fd nor with marlin kimbra, but I have used the Tiny OLED successfully with an Arduino Due using Andrews modified RAMPS 1.4.

Can you post a photo of your Tiny OLED and how it is connected to the ramps-fd?

What would need to be edited in Repetier-firmware to get this to work properly?

I don't use Repetier firmware, but may be this thread will help you...

Nice find.

If I'm understanding that correctly, the display is already implemented and I just need to comment in/out the relevant lines in uiconfig.h

If so, that's awesome.

Thanks for linking me to that.

I had enable the #define U8GLIB_SSD1306 and sd but my oled stucked in menu, not responding to encoder. The x,y and z is keep flashing as shown in the attached picture.Did I missed anything on tweaking the Marlin firmware?
I'm using Marlin 1.1.0-RC8. My oled and encoder is working fine( tested with example sketches).

I still use an older version of Marlin, but from what I read, the blinking coordinates just mean that the corresponding axes have not been homed yet. So that part would be normal in your case.

As for the non responding rotary encoder, I assume that there is some problem in the pin assignment. Check out your values for BTN_EN1, BTN_EN2 and BTN_ENC (probably defined in pins_RAMPS.h) and verify them with your wiring.

Thanks! The encoder works now. I forgot the code section for pin assignment. To make it work(Marlin1.1.0-RC8),

At Conditionals_LCD.h add:
// Generic support for SSD1306 / SH1106 OLED based LCDs.
#if ENABLED(U8GLIB_SSD1306) || ENABLED(U8GLIB_SH1106)
#define ULTRA_LCD //general LCD support, also 16x2
#define DOGLCD // Support for I2C LCD 128x64 (Controller SSD1306 / SH1106 gaphic Display Famiy)
+#define ULTIPANEL
+ #define NEWPANEL

#endif

and at pins_RAMPS.h add:
#if ENABLED(NEWPANEL)
.
.
+#elif defined(U8GLIB_SSD1306)
+ #define BTN_EN1 31
+#define BTN_EN2 33
+#define BTN_ENC 35
+ #define BEEPER_PIN 37
+ #define LCD_SDSS 53
+ #define SD_DETECT_PIN -1
+ #define KILL_PIN -1

I'm trying to get this working. I have the OLED working. Setup was a snap with the current version of Marlin. I connected an encoder as shown in the schematic. No joy. So I added the following lines to Conditionals_LCD.h:

#define ULTIPANEL
#define NEWPANEL

After re-uploading the firmware I got a flashing screen. After some monkeying with the encoder I got the screen to change but would not allow any other movement via the encoder. Next step was to add the other lines to Pins_RAMPS.h:

#elif defined(U8GLIB_SSD1306)
#define BTN_EN1 31
#define BTN_EN2 33
#define BTN_ENC 35
#define BEEPER_PIN 37
#define LCD_SDSS 53
#define SD_DETECT_PIN -1
#define KILL_PIN -1

This will not compile. I'm sure I am doing something wrong. My apologies as I get lost on really complex code for the Arduino etc. I suspect I do not have these line entries in the correct place in the pins file.

Lastly, if this matters. I am not using a buzzer.

Thank you in advance.

Are you really sure that you have U8GLIB_SSD1306 defined? And not U8GLIB_SH1106?
I use the latter one for the 1.3" displays, the former for 0.96" displays.
Re: DIY Tiny OLED I2C full graphics controller
May 18, 2017 10:54PM
Yes SSD1306 in Configuration.h (from the file)

//
// SSD1306 OLED full graphics generic display
//
#define U8GLIB_SSD1306

//

Thank you.

Somehow your last message does not fit well with your initial version, where you use U8GLIB_SSD1306 and define it in Configuration.h.
Where does SSD1306_OLED_I2C_CONTROLLER come from and where is it defined?

And the way you are you using #elif seems rather suspicious to me. Why not just #if and use #elif to replace the following #if ?
Re: DIY Tiny OLED I2C full graphics controller
May 19, 2017 11:33AM
I was simply following the comments and code snippets in the thread. I am not a coder. (Although I wish I were)

The example I was using is in the last post by ilo.

As I think I said in my initial post I'm sure I am doing something wrong.

Thank you.

Thank you again. After work I'm going to blow away my current Marlin folder and create a new from the Zipped file.

I'll report back my results. I had the OLED working. Now to beat the encoder into submission.

And It compiles now.

I downloaded the 1.1.x version and it's compiled. I have to go take care of some personal business and will upload the firmware to the board when I return and report the results.

Thank you for your help.

Re: DIY Tiny OLED I2C full graphics controller
May 19, 2017 08:37PM
And I am happy to report it mostly works. The only real issue I have is with the encoder. You have to turn the thing three clicks to get it to move to the next position on the menu. The encoder also seems to work backwards from what I expected. But it now works. The rest I hope can be fixed via tweaking.

Thank you again. I am grateful.

Re: DIY Tiny OLED I2C full graphics controller

In Conditionals.h just comment out the line
#define REVERSE_ENCODER_DIRECTION
and in Configuration.h uncomment and adjust the values of
#define ENCODER_PULSES_PER_STEP 1
#define ENCODER_STEPS_PER_MENU_ITEM 5
too your liking. Hope that helps to resolve the remaining problems.
Re: DIY Tiny OLED I2C full graphics controller
May 20, 2017 10:23AM
That does solve it for me. Perfect! Some tweaking on the menu steps and it now works as I prefer. I've added the buzzer and need to complete the configuration of my Prusa-ish printer. This was a big hurdle to cross.

I want to thank you for posting this project. Thank you for the kind help and also thanks to all who contributed to this.

I really dig these little OLED displays and use them extensively through my projects. I even prefer them over the common 1602 and 2004 LCDs for text.

And I am happy to report with some help from the folks on the dev team I have this OLED/Encoder/Beeper working on Repetier 1.0-dev

I'll post the settings to configure this later this week once I can sit down and sort it all out into all the steps needed.

I already have a 2.42" OLED working. However that one you link on FeeBay will not work. I have 2 and I've tried. They claim it's also I2C but nobody can seem to get that to actually work as I2C.
