I set down my Maple board for some time and I'm now looking into playing with it once more.
With the help of Rod from the leaflabs forum, we created a library to use the RTC inside these devices. This is still stored on my GitHub. Do you think this could perhaps be added to the rambutan libraries?
The reason I ask is that there seems to be a fair amount of changes on the rcc.c and rcc.h files that originally had a bug and I'm not quite sure whether this has been fixed or not.
I did notice some time ago that the stm32duino has our RTC implementation included... so it's only fair that librambutan also has it.
