ds3231_tivaC
ds3231 RTC port for the tivaC. Customized for personal use so read the code carefully before using
Notes
This code is hardcoded to use i2c0 of the tivaC, to change it you need to change the macro DS3231_I2C_BASE and either change also the init function or dont't call it and initialize the i2c module on yourself.
Documentation and Examples
Right now Doxygen style comments are provided in ds3231.h file, I may build the docs and deploy it later
Example of code using the ds3231 is provided in main.c
Credits
I took the register definition from Google Android source code at here. The logic is just implementation from the datasheet
