I've been looking for a 4-bit grayscale graphic oled ( with a SSD1329U2 or similar spi controller/driver)... I notice sparkfun only seems to carry the color version (SSD1339 spi driver) Thanks for the info!

I'm hoping to find an oled that has a spi interface. I see this project uses spi for the rtc, but doesn't say what the interface to the oled is... Anybody know where I can find more info on this oled? What’s the part number for the oled?

I used a soldering station with a microscope to do a lot of it, although I think now that I've done it, it would be possible but still difficult to solder most of it without a microscope. lossforwords1: yup.

I ran the numbers and for a batch of 100, each clock would still be $70, which I think is too much to try to market. It becomes more interesting if it's not just a clock, but a usb slave device that can be programmed to display anything, but I never tested the usb device port nor wrote any software for it. lexity: I’d love to have the time to try to make a bunch of these and market them, but I just don’t.

They have a standard data bus interface + 6800 or 8080 control signals. There's also an spi interface. arm vs avr: I have a couple gizmos that use arms and the battery life seemed very good. That and it just seemed like there were more linux tools for the arm (assembler, compiler, jtag, usb programming) at the time. jetforme: eagle: Still havn't posted them. I want to remove the crystal and replace it with an oscillator, since it was the crystal that made the board not work. And, it's likely I won't have time to print another clock board and populate it before next year. libraries: I defined every part myself for my own library, because the quality / consistency of the ones I found on the web were sub-par. penjuin:
