The white-on-blue screen that shipped with the #twatch really requires the backlight to be visible. Here’s an updated firmware that has the backlight on at power-up. The new firmware is loaded over the network using tools already available in most operating systems, Windows instructions here.

We apologize for the lack of refinement. We prototyped with a cheap grey-on-green screen that didn’t normally require the backlight. The firmware posted to the Google Code project page went into the Seeed #twatches unmodified to ensure that yours matched the original. Everyone would probably have preferred that the #twatch ship with the backlight enabled by default.

In the next update we’ll tweak the refresh rate and scrolling speed. Do you have any other specific requests for the standard #twatch firmware?
