Create RTC Driver - Githubissues

GMUSatCom commented 5 years ago

Create a Driver for the RTC. Must support the following features:

[ ] The ability to set alarms which call specified callback functions. One second of resolution is required.
[ ] The ability to queue alarms.
[x] The ability to update time and date from an external source.
[x] The ability to get time and date.

After this feature is in, we can begin writing actual code for the bus since we will now have a way of scheduling when activities occur in orbit.

For Alarms, I have decided on the following requirements:

[ ] Alarms can be told set to be triggered for a certain number of times at a regular interval starting at a specific time. For example, the user could set an alarm that fires four times, once every 5 minutes, starting at 13:50:55 AM on Saturday November 2nd 2019.
[ ] Alarms will not require any dynamic memory allocation to work.
[ ] Alarms will have a simple function that blocks a task pending the alarm.

I'm not sure yet, but I also think that it would be pertinent to make alarms persistent on FRAM devices so that restarts do not effect the RTC system. I don't know if that would make it harder to reason about the way the system behaves though, so we will have to discuss this at some point. It may just be better to mark individual alarms as part of persistent memory instead.
