A library to support the PCF8523 over I2C when using a pico. Comes with a very basic live test. Currently, it only supports the bare minimum to get the RTC up and running.
- Reset
- RTC Start
- Enable battery switchover
- Set datetime
- Get datetime (with trust flag)
- Alarms
- Low voltage mode
- Low battery detection
- Interupts
- Probably support the rest of the features someday.
- Model check my implementation against an i2c state machine for testing.
