0.50 inch to arduino

hi,

I'd like to connect this micro display (Full Color Oled Microdisplay - Buy Microdisplay,Amoled,Oled Display Product on Alibaba.com) to an arduino... I'm an IT engineer, so I'm good in computer programing but not in electronic :frowning:

Anyone could help me ? Is it plugable to a shield ?
Thanks

It looks like it needs an input video signal, ie. the module has no built-in framebuffer.

It won't work with Arduinos.

There may be hope yet…

I sent them an email but they’re in China so I don’t know if they are going to respond.

Yes, I saw that. The I2C interface is only for adjusting brightness/contrast/gamma/etc.

See this page: http://www.olightek.com/products_detail/&productId=34.html

Maybe you could use a Gameduino and one of their input conversion boards:

“Video Signal interface: ITU-R BT.601/656”
see attached.
(it’s all Greek to me)
I did catch the serial data rate though, 270Mbit/sec.
Isn’t that going to be a little hard to do with an Arduino running at 16Mhz ?

I could be wrong but I think this means the clock would have to be 27Mhz

clock period (625): T = 1/ (1728 x f H) = 37.037 ns
clock period (525): T = 1/ (1716 x f H) = 37.037 ns
clock pulse width: t = 18.52 ± 3 ns

Thanks for your replies :slight_smile:

So, if I understand well, I need a board for the display that will convert the signal in order to communicate with a module (like arduino). Is that it ?

I found this : Oled Micro Display Driver Board - Buy Oled Display,Micro Display,Display Product on Alibaba.com
They call it a "driver board"... does it help ?

Thanks (again) :slight_smile:

Specifications

1.This OLED driver board can compatible with 0.5''OLED microdisplay.
2.video input.

Product Name: DRV050-CV-R01 OLED microdisplay driver board
Model: the driver board for 0.5'(SVGA050V1) OLED microdisplay
System format: PAL(640X480;720X480;768X576)
Voltage input:DC 5-10V
Structural dimension of PCB (mm):29(W) × 29(H)× 1.6(D)
Work temperature:-40~+65 °C
Relative humidity:5~95% RH
Storage humidity:-55~+90

It looks like it requires a PAL input .
Do you have one ?

For the moment, I have nothing ^^
I'm investigating how to realize my project. But electronic is like Greek to me (too lol). So I ask to people who can help me.

If it could work with a PAL input, I can buy one and plug it to the arduino board... No ?

It's the programming that's still geek to me.
I don't have any problem with the electronics, but there was none in the standards document. (unless
you count the timing diagrams that were there for the programming reference.)
So you don't have the display either ?
What is your project ?

No, I don't have the display yet.
I have a motorcycle, my project is to build a helmet like this one :

With a microdisplay, I will be able to project the screen imagine on a translucide surface (like the Google Glass) in front of my eyes.

In fact, I need a very small display with high resolution. Maybe an arduino module like that already exists ? but I didn’t find it.
If someone has informations…

Thanks :slight_smile:

I don't want to rain on your parade but I met a guy once who worked at a company that makes the 1"x1" flip down
HUD display for attack helicoptors and he told me is was 10Mpixel. (3162 x 3162).

Yes, I guess army equipement is very high quality. But a high resolution (like the one you said) is not required for my project. The max I need is 800x600.

I also found the 4D Systems µOLED-96-G1. It seems compatible with arduino, right ?

Why didn't you say that in the first post?

Arduinos aren't the way to do this. They're microcontrollers, not video devices.

You need something with way more RAM, way more processing power, USB inputs to connect cameras, etc. ... and a video output.

They have adapter boards for that screen which will accept most video formats, you'll probably need one of those because you're unlikely to find anything with "ITU BT.601/656" video output.

Yes, but it's only 96 pixel resolution and there's no way to put live video on it.
