• Version 1 fail and new planned features

    Upon assembling the Rev. A boards, it turns out both the battery gauge and the BMP280 were wired wrong... FAIL !

    Nonetheless, I have started work on implementing BLE connectivity, and it is looking pretty good so far, with a link with an iPhone already being achieved.

    I have also decided to swap the LSM303 with the Bosch BNO055, which will allow for more precise compass measurements and also adds a gyroscope, which I plan to use for a "flick of the wrist" wake.

    The power section will also be improved, ditching those "old tech" SOT-23 charger and regulator with nice DFN and QFN package chips, the TI BQ24075 battery charger and power path management IC, and the TI TPS71433 3.3V LDO Regulator, thus going full Texas Instruments on the power section.

    Finally, I have also implemented haptic feedback with the TI DRV2605 haptic controller, to have some haptic feedback for button presses, IOS notifications, etc.

    More updates to follow

    I've finally started work on the RWatch, and already have part of the UI done. The next step will be to create an animated menu, and add other sofware features such as a stopwatch.
