# MabezWatchOS

This is the firmware the Smart watch I am creating runs on. This code was originally created for use with an Arduino Nano but has evolved and adapted to the Teensy LC (3.x is also compatible with a few register address changes) and now the STM32 ARM 32bit microcontroller.

## The Operating system

### Notifications

  - Receive and break up the serial data into title, text, package name

  - Hold multiple Notifications in RAM

  - Remove notifications

  - Display a whole Message (the text)

  - Control the flow of notifications (I.e if we run out of space we tell the App to hold the notifications in a queue ready for when we have space to receive more.)

  

### Weather Data

  - Receive and break up the serial data into Day, Temperature and Forecast.

  - Provides a time that the data was received so we know if the data is accurate or not.

  

### Date/Time

  - Provides a nice Interface to see the time, like a classic clock face and a digital clock

  - Wouldn't be a watch without this functionality

  - Checks the RTC has the proper time everytime we connect to the app

  - Timer, simple timer to time hours seconds and minutes with an alert to shop when the timer is done

  - Alarm, utilizes the 2 alarms available on the DS3231 RTC with easy to use interface.

  

### Input and gestures

  - Dual click (UP & DOWN together) to go back

  - Tri Click (ALL THREE together) to go to the home page with the favourite widget selected from the settings

  

### Other functionality

  - Settings, store basic settings on the on board EEPROM

  - Can reset the BT module if it fails to connect after a while.

  - Smart shutdown, instead of a clunky off toggle switch, we drop the watch into hibernation mode and can be woken by pressing the OK button at anytime.

  - Crash handler, usuing the built in watchdog timer we 'kick' the dog every cycle, if the dog does not get kicked it resets the watch (Disabled when Shutdown).

  - Status bar showing connection, battery and notification information.

## The Hardware

  - 1.3 inch (128x32) monochrome OLED (Black & White)

  - Capacitive touch buttons, instead of clunky tactile switches.

  - DS3231 RTC with alarm and temperature(not implmented currently) functionality

  - HM-11 Bluetooth 4.0 low energy transciever

  - TP4056 single cell lithium charger board

  - Single cell 240mAh lithium ion battery

  - Teensy LC (48Mhz) (Soon to be replaced with STM due to difficulty getting the bootloader from PJRC Store)

  

### Power Specifications

  - Draws 24mA on average when operating normally.

  - In Shutdown mode it draws 550uA

  - Power on time: Over 8 hours

  - Shutdown mode timer: 18 days

  - Quick charge under an Hour
