#esp8266-smartwatch This project is by Shantanu Goel for a smartwatch based on ESP8266. This software repository consists the following development:

• Modify and refactor Tuan PM's port of the MQTT client library for ESP8266
• Use zarya's I2C driver
• Modify and refactor this OLED driver
• Add an NTP driver and a client

Thanks to Nathan for the original code that combined the mqtt and oled drivers

The aim is to build an extensible smartwatch framework which is easily configurable

##Hardware

• ESP8266 (Developing currently on ESP-01 but others should be usable as is)
• A 0.96" 128x64 I2C OLED which is easily available from ebay or other electronic shops
• A 3.3v USB FTDI board for programming/powering the esp8266 and the oled during development. Will be replaced by a LIPO battery finally

##Current Status

• Subscribes to an MQTT topic and displays it on the OLED
• Using this with tasker on phone and ThingFabric to send phone notifications to the watch
• Gets the current time from NTP server at boot up and displays on the OLED

##Changelog Check commit history

##Configuration

• I2C address for the OLED is in include/driver/i2c_oled.h
• MQTT broker and WiFi settings are in include/user_config.h
• GPIO pins to use for I2C are in driver/i2c.h
• MQTT topics to subscribe to are in the MQTT_Start() function in user/mqtt.c
• What to do with the incoming messages is defined in deliver_publish() in user/mqtt.c
• NTP server IP address is in user/ntp.c

##TODO

• Decouple OLED code from ntp
• Build clock function on top of the ntp client to update display with latest time
• Refactor MQTT code and segregate wifi and ntp/clock management from it
• Refactor OLED code to better manage all the different writes ongoing and prevent a write wiping out other things on display
• Add framework to configure things for individual users without having to recompile the code
• Add watchfaces (wishlist)
• Add buttons support to take actions on the watch
• Add communication support from watch to phone
