I am wanting to use a small OLED display in a project i am working on and was wondering if it will work similarly to the lcd included with our nerdkits, ie: data bits being the same. A display i would like to use is one of these - OLED display - but if someone knows of one that might work better with our kit feel free to let me know. Thanks for any help.

Define "similarly". That looks like a graphical display. Those are very different from the character-oriented display that comes with the Nerdkit.

With the Nerdkit LCD you send text characters to it and it displays those characters in a 20x4 grid of characters. With that graphical display you send pixel data to it and it displays a grid of 128x64 pixels.

If you want to display characters on a graphical display you would need to form the characters one pixel at a time unless the hardware includes an internal font. It doesn't look like that one does. I'm sure there are AVR code libraries available to do that for you, but they're not going to work the same as the libnerdkit/lcd.h.

aspeth20, please keep us posted on your progress. I also picked up a couple of graphical LCD (Nokia cell phone) displays but have not had time to play around with them yet.

I think having a graphical display would be neat, we might need to daisy chain a couple of micros together (master/slave) in order to have the processing power.

I think the atmega168 should be good enough for static text and drawing. To do animation or large raster imagery would be harder.

I found this - OLED- which should work fine. It has a built in processor to communicate with the 168 (or other microcontrollers) via serial commands. Looks pretty cool.

That's neat. It has an SD card reader on board so you can store photos and animation on the card, so the MCU only has to send commands telling it what to read from the card.

That is a neat device, to bad one can not purchase it!!

I followed the link to their store but there is no ĀµOLED-96-G1(SGC) found.

Please post a store link, I want one.

Keep in mind, those displays are TINY. They are less than an inch tall and around an inch wide. I must admit, they are nice to look at. BigGrin
