FC v4c Updates V1.1.1 (#41)
Browse files Browse the repository at this point in the history 
* Updated to pet the watchdog

* Create rv3028.py

* Update pysquared_eps.py

* Changed the Boot Count Iter

The boot count now iterates in the pysquared.py rather than in the main.py

* Update pysquared.py

Fixed bug with setting the boot count in NVM before the microcontroller is correctly setup

* Update main.py

Added c.hardware["WDT"] toggle to main

* Update pysquared.py

Added RTC Get/Set Time & Date

* Update code.py

* Ran Linter
