chipKIT Built-In Real Time Clock
The Microchip® PIC32MX320F128 based UNO32 features a native RTC system.
The chipKIT™ Uno32 reference manual provides all the details: |
RTCC: Real Time Clock Calendar.
The PIC32 microcontroller contains an RTCC circuit that can be used to maintain time and date information. The operation of the RTCC requires a 32.768Khz frequency source. Crystal X2 (not loaded), just above and to the right of the PIC32 microcontroller IC, is provided for you to solder a 32Khz watch crystal. The Citizen CFS206-32.768KDZF-UB crystal can be used in this location. |
On the software side, I wrote a basic RTC library available here for download.
Other features are described on the PIC32 Family Reference Manual, Sect. 29 Real-Time Clock and Calendar (RTCC). |
