actually the bleeding edge in open hardware smartwatch / smartclock / IOT is right in here:

http://www.stm32duino.com/viewtopic.php?t=591

not sure if it might just become a commercial product / reality sooner than later
the idea of an open hardware smartwatch is attractive, bored with the current watch face? develop a new watchface (i.e. app) say using an IDE say arduino IDE / eclipse, connect the USB cable, install that in flash via DFU update & reboot, viola a new watch literally

i'd think 'modular extensions' just like arduino shields is also possible, add a gps? plug that module in connect the usb cable install a new firmware using DFU update flash & reboot ! this i'd guess would be similar to the modular smartphone concept

@ag123

I don't think @FurkanCetin finished it. The last posting was some time last year

I dont wanna be the fun killer here, but there are (totally cheap) special chips who can handle things like smartclocks even better than a STM32Fxxx can ever be:
Example: Mediatek: MTK6260, MTK6261
So it would be a better aproach to get into the SDK of these. (and/or buy a smartwatch like the Aplus GV18 (I own one for less than 20 Euros)) and do some reverse engineering, because the firmware is bad as hell.) Starting point would be this: http://codeasm.com/U8/ but I assume there is no real english documentation out.

No datasheets? no thanks.
If i remember correctly pebble still uses STM32F processors, while having a much smoother experience AND interfaces than the cheapo china smartwatches IMO.

EDIT: There it is, Step 9. And it still has a longer battery life than other smartwatches. (with a color display)

just got my stm32 evo primer (open4) ordered from element14, it is literally 'flying off the shelves' (i tried to find a link to it and discovered that it is 'missing' probably sold out

my impression with the device is wow !

below is a link to a youtube video found about it, not from me:

Pebble uses ST Micro STM32F439ZG 180 MHz ARM Cortex-M4-based MCU, as written in the teardown.

gui on stm32f7 by st itself, but of course f7 is pretty high end and fetch a premium (i.e. somewhat costly) & brings it to a level competing with the ghz superscalar arms & intel :lol:
