==Objective==
Here we use mCookie to build a simple watch, which can synchronize the time automatically in the WiFi environment.

==Principle==
We add the WIFI module in the tutorial, which can connect to the pre-set network after the power-up of the mWatch. When it is connected, the mWatch will synchronize network time automatically. And then acquiring time through the RTC module and displaying it on the OLED screen.

==Program Description==
*Acquire network time function: " updateTimeData()"--Execute the statement to get the network time.  
*Acquire RTC time function: " getRTC()"--Execute the statement to get RTC time.  
*RTC time adjusting function: " setRTC()"--Execute the statement to re-set the RTC time. 
*Notice for network connection initializing can be displayed by the OLED screen. (Inside setup() function.)
**Search for network: If successful, it'll pop up notice " softap ok " or it'll show " softap err ".  
**Join in network: If successful, it'll show notice " Join AP success " or it'll show " Join AP failure ". 
**Note for time acquiring: If successful, it'll be displayed on the OLED.  
==Code Debugging ==

*Find this section of code above in the main program, enter WiFi user name and password in "". So it can connect to the internet and get precise time information. 
*Find this section of code above from the rtc.h program, modify it as your time zone; Load the program to the CoreUSB after modifying and get precise time under WiFi environment.
