Build Instructions
To be able to successfully build the project you need the inkscape and
magick executable and a ARM GCC toolchain in your path. The resulting binary
is ready to be flashed onto the controller.
cd timekeeper
xargo build --target lpc1227-none-eabi --releaseTo execute the tests, run cargo test.
There are some features you might want to activate.
semihosted: Enable debug output via the semihosting mechanism.fake_time: Do not wait for a valid DCF77 time, but just assume a hardcoded time value.stay_awake: Panic instead of going into Deep Power-Down mode.
Warning
The PCB layout is not up to date!

Questions
How big is the Eink clock PCB?
It measures 80 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Eink clock use?
81 parts, built around the LPC1227FBD48/301,1, LM2611BMF, TPS61041DBV and TS321ILT. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Eink clock KiCad files?
From the kaini/eink-clock repository on GitHub, at the commit this page was made from: the board is kicad/einkclock.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Eink clock design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
