RP5C01 V1.0

26 Oct 2020

The First One: RTC Card built and driver implemented in RomWBW.

Completed a limited implementation of the HBIOS RTC driver for the RP5C01 RTC chip. Can set and read the date and time.

Next steps for the RTC:

  1. Implement the HBIOS routines to access the NVRAM section

  2. Create cp/m app to allow for calibration adjustment of the timing.

Currently the HBIOS driver has not been merged. Its currently sitting in my fork at : https://github.com/vipoo/RomWBW/tree/dean/dev-rtc (Driver is in file: /Source/HBIOS/rp5rtc.asm).
