RTC Emulator

Posts: 208
I have been using the Propeller_RTC_Emulator object in one of my projects.
It seems to me that the current minutes Should be stored in the variable MM in the Propeller_RTC_Emulator_DEMO object.
However, when I print the value to the screen using the vga_text Dec function, it prints "0".
Can anyone explain how to get the minutes value from this object?

I may use your RTC Object later, as it seems a bit more robust than the RTC_Emulator object, but I have solved the problem.
I added a function that returns the value of the MM variable inside the RTC Object, and that seems to work fine.
Thanks for the help!
