This chapter introduced you to the RTC framework and its API. Its reduced set of functions and data structures make it the most lightweight framework and easy to master. Using the skills described in this chapter, you will be able to develop a driver for most existing RTC chips, and even go further and handle such devices from the user space, easily setting up date and time, as well as alarms. The next chapter, PWM Drivers, has nothing in common with this one, but is a must-know for embedded engineers.
