Leta - Wrist watch with my ownRTOS and GUI !

Many of us saw through the wrist watch made by Zak's Electronics right? The first time I saw it, I wanted it so so bad. Then I try to create mine. I ve been searching for a long time and then found another one made by ZeekiChen using their chinese Mcu. He made the GUI great so far that can move, and do page switching. Then I know, this is absolutely right thing for me to align with. Then I complete the GUI like the update version of ZeekiChen's gui, which can fade, move, resize objects. I get my watch working with GUI, but there still have one more thing can be improve, that is the OS! So first thing in my mind is freeRTOS. Fortunately, at the same time im trying to create the miniRTOS for use in AK-base-kit board using stm32l1 (ARM cortex m3). So I made them work together(The OS and the GUI) in my own dream watch. What you guys seeing now is the result of 1 year I ve done when still being a last year student at university.

Because my skill in hardware is not good, I didnt think that much, so I made the auto shutdown circuit to achieve extremely low power, but BKP and RTC domain still remains to update watch time.
