We have an example Android app that just went up. It's currently available for testing at

It shows how to connect and pass simple notification data- texts and incoming calls at the moment.

Our example watch code is available at

Unfortunately 1632 cells can't support the current draw from the OLED. A small lithium polymer battery is the way to go if you're able to solder one on.

TinyDuino / Re: TinyScreen uses both Wire and SPI?

Missed this Mike. The OLED on TinyScreen uses SPI for data and commands, but the chip select and other control lines(along with the buttons) are attached to an I2C GPIO chip. This trades 7 I/O on the main controller for an I2C address, which allows TinyScreen to be compatible with all our other boards.

The Wire library has unnecessary overhead, but we want to cause as few software conflicts as possible- you can definitely change the buffers to be very small, 2 bytes should work without causing issues in the library logic, but I haven't tested that.

Hi Chad and Mike, we now have the library maintained at

It is also currently being integrated into codebender's supported libraries, so the included library files in codebender examples will go away and the maintained codebender library will be referenced instead.

There have been a few bug fixes done, but I'd like to figure out that setBrightness() issue. I haven't been able to reproduce the issue, so please post your example project.
