Spider mainboard RTC

Hi, following this example
https://www.ghielectronics.com/docs/29/real-time-clock-rtc

I’m trying to burn RTC to my spider, but i can’t find the GHi.Processor dll, (4.2)
Is it possible to use RTC on spider mainboard?
thanks

@ bioengproject - Are you really using MF 4.2?

The RTC class would be in the hardware namespace.of premium library with 4.2.
