/** @mainpage Sensor Watch Documentation
* @brief This documentation covers most of the functions you will use to interact with the Sensor Watch
hardware. It is divided into the following sections:
- @ref app - This section covers the functions that you will implement in your app.c file when designing a
Sensor Watch app.
- @ref rtc - This section covers functions related to the SAM L22's real-time clock peripheral, including
date, time and alarm functions.
- @ref slcd - This section covers functions related to the Segment LCD display driver, which is responsible
for displaying strings of characters and indicators on the main watch display.
- @ref buttons - This section covers functions related to the three buttons: Light, Mode and Alarm.
- @ref led - This section covers functions related to the bi-color red/green LED mounted behind the LCD.
- @ref buzzer - This section covers functions related to the piezo buzzer.
- @ref adc - This section covers functions related to the SAM L22's analog-to-digital converter, as well as
configuring and reading values from the five analog-capable pins on the 9-pin connector.
- @ref gpio - This section covers functions related to general-purpose input and output signals.
- @ref i2c - This section covers functions related to the SAM L22's built-I2C driver, including configuring
the I2C bus, putting values directly on the bus and reading data from registers on I2C devices.
- @ref spi - This section covers functions related to the SAM L22's built-in SPI driver.
- @ref uart - This section covers functions related to the UART peripheral.
- @ref deepsleep - This section covers functions related to preparing for and entering BACKUP mode, the
deepest sleep mode available on the SAM L22.
