Introduction: How to Use OLED Display Arduino Module
Hello guys, this is the first time we(smart prototyping) post an instructable here, thanks for watching! We will keep on post funny instructable, hope we can help you a little and communicate with your guys!
Here is the 0.96 inch OLED display instructables for how to display chars and binary BMP picture.
This 0.96inch OLED display has 128x64 resolution, three kind of light color, blue light white light and blue/yellow light, I think the blue light has better display effect than the others. The display with small dimension, very suitable for smart watch, function cellphone, smart health device, now let's start using it to display chars and a Bentley logo picture.
No need to understand any code here, just following the step to do it, you will know how it work and you can control it whatever you like to display.
Here is our product page:
Step 1: Connecting the Module to Arduio, This OLED Module Have Six Pins,
Connecting the module to Arduio, this OLED module have six pins,
OLED-------Arduino
D0-----------10
D1-----------9
RST----------13
DC-----------11
VCC----------5V
GND----------GND
Step 2: Copy the Code in Arduino IDE, and Change the Chars in Function "LED_P8x16Str"
down load this Arduino code, and copy it to Arduino IDE.
Find below code in the bottom,
void loop()
{
LED_P8x16Str(23,0,"welcome to");
LED_P8x16Str(40,2,"Smart");
LED_P8x16Str(20,4,"Prototyping");
}
Here you can change the comment that you want to display in line 1, line two, line three. The first and second parameter is the starting x,y coordinate.
Step 3: Upload the Code
Upload the code, then you will see the text showing on display now!
Step 4: Now Start to Display a Bentley Logo
Here is the bentley logo picture here, transfer the picture to 128x64 pixel, save the picture.
if you don't know how to transfer the picture pixel, please download the 128x64 bmp here
Step 5: Transfer the Pic to Binary Code
Use the following soft transfer the BMP code to binary code,
Download bitmap_converter
save output to "logo.txt", open the logo.txt you will see the picture's binery code in
const unsigned char logo [] = {
...
};
Step 6: Copy the Binary Code in to Arduino IDE
Copy this example code(code-bmp.txt) to Arduino IDE
Instead the picture binary code in example code.
find the "
const unsigned char logo[]
"
and copy the code to this funtion. if you don't understand this step, you can just run the example code...

Step 7: Upload Code Done!
Now you can see it display on the OLED!

Hi is it possible to change the size of the text and the color even if I think I have a monochrome I could always thank thank you very much of your work is the only code that works for me

Did you ever get an answer to this? I'm looking to do the same thing and I have not been able to figure out how to accomplish this. Thank you!

get a message tthat says "led not declared in this scope." what does this mean?

HI,
Iam used arduino uno , 6pin OLED , gps
iam getting output without including gps code but iam getting warning like Low memory available, stability problems may occur.
When include gps code the memory was full i can't able to upload the code.
How can reduce the memory?
Is there any other option?

Struggled with this after the Adafruit_SSD1306 examples which said to attach CS to pin 12 on Arduino. Decided to attach it to GND instead (due to experience with other LED screens) and your sketches worked just fine. However to stop screen burn suggest the following lines added in void loop.
delay(5000);
LEDPIN_Init();
LED_Init();
delay(5000);

Does that loop turn off the screen periodically?

Refreshes it.

Hey!
I ported it to STM32 on I2C, and it was a really big help to use your code. Thank's a lot! ;)

Connect CS->Gnd

Hi Rezak33,
I never met this, maybe you could try to change the power supply or the connection is stable or not. Thanks.
Tip 5 years ago on Step 3
Do connect CS to Gnd

I use the code for text but after a while OLED became noisy!! any idea what happened or whats wrong?
thank you

hmmm ... great code ... it seemed to verify/compile without warnings or errors. However ... on my display, which looks identical to the one in your images, the bitmap image looks like it has some "moving artifacts" ... it's probably better explained with a video (below). The text just says "TEST" bit it looks like it's trying to scroll or something. I've reduced the bitmap to a single letter and it still has that movement in the bitmap image ... weird ... I'll continue to test but I was hoping someone else may have some idea as to what is happening here. Thanks for any input.

If your oled has a 'cs' port try to ground it and reset the arduino

Great tip, thanks, now the display is working. Could you explain (or refer to an explanation of) what the CS pin does and why it has to be connected to ground? Thanks!

I had the same problem, and fixed it by grounding CS.
CS means "chip select". It is a line used to select or activate one chip/module out of maybe several. In this module it should really be named CS- or CS*, meaning it is asserted when /low/.
If it is left open its state will be indeterminate, and very likely alternating between low and hi as it is affected by ambient electrical fields. Connecting it to ground makes the display permanently selected and respond properly to everything else.

Thank you, that's a really helpful explanation! It's always nice to know *why* something is working instead of some 'magic' that I can't explain...
