We have now added real-time time and date support for RISC5 FPGA Project
Oberon systems by connecting them to a Maxim DS3234 RTC chip via the SPI
interface. This device includes a battery backup system and keeps time with
an accuracy of +/- 2 minutes per year.


The RTC feature enables automatic timestamping for Project Oberon files, and
allows the implementation of remote datalogging applications and any other
applications that rely on accurate timekeeping.


The source code and all the implementation details are included in the
Astrobe for RISC5 section of the Astrobe Forum:
