I have got a bunch of small OLED displays but no time to play with them.
I would like to give them away so you guys can have a go at it.
The only 'payment' is that if you got it to work then you must make a post about it and share your code for all to learn from.

I got a picture. Details about the resolutions will follow later. Except the big one they are all serial through spi/i2c/serial.

Please post here if you want one as my pm box is often full.

Hi TZA,

Do you have any 'bi-colour' oleds amongst this lot??
I am after a graphical oled (SPI or I2C) with the top 16(ish) pixel rows in yellow/orange, and the rest of the (bottom) rows in blue. I am about to order from China but they get put on a slow boat. If you have any then I am more than happy to send you some 'beer funding'.

Regards,

I have the one on the top right side, it's actually transflective and not OLED but requires some capacitors to work properly. I have a schematic and some c code if anyone is interested I could share it. It is a neat little screen, which I use on my nfc payment handhelds, it does not consume much power with the backlight off and is visible in the daytime too which is a bonus.

Good evening TZA...

Would the big one be compatible with the current LCD uMite interface..? ie HD44780 parallel interface..?

Also, there was talk of using a OLED unit with a "modified" DIP-600-28 board I just got going... The one on the second row to the left looks about the right size to possibly fit correctly... I never herd any feedback about PDF information on anything... Would you have the part numbers for these units..? What kinds of interface connectors would be needed..? Just looking at some possibilities...

Looks like a nice selection of toys..!

I need some more time to get the exact information as I accidentally deleted my email with all the part numbers. I have requested a copy from the seller so I wait for that.

@WW The one on the lower left corner is a similar module (except the 2 colors) sand has the exact same controller.

@akashh Yes that is right it is an LCD and needs some extra parts to function right.

@Zonker. That one is special as it can be used with a 4 or 8 bit parallel, SPI, I2C and serial connection. I am going to use this one to experiment on myself.
The one on the second row is a 96x16 oled with spi/i2c.

Once I get that email I can match them again with what I have and have exact info together with schematics and sample code (not MMBasic).
