RTC Libs.

One of the things that I would like to get working is the RTC on the STM32F103XXX – We briefly touched on this before.

Most boards have a 32,767 Hz oscillator or crystal on them and therefore only need a battery/battery holder (possibly with an in-line schottky diode, put probably not) to allow us to get the RTC operational.

What I have discovered so far.

1) There is some sort of attempt to get this working in ./hardware/Arduino_STM32/STM32F1/libraries/Untested/RTClock/
This is incomplete and incompatible with the current versions of rcc.c and rcc.h

There is a “new” version of the rcc libraries in ./hardware/Arduino_STM32/STM32F1/libraries/Untested/RTClock/new RCC/
This is not compatible with the current rcc libraries either.

2) I am unclear which rcc.[h,c] I need to try to merge or adapt the changes form “new RCC” to as there seem to be a number of candidates.

./hardware/Arduino_STM32/STM32F3/cores/maple/libmaple/stm32f3/include/series/rcc.h ./hardware/Arduino_STM32/STM32F3/cores/maple/libmaple/stm32f3/f3_rcc.c

./hardware/Arduino_STM32/STM32F3/cores/maple/libmaple/include/libmaple/rcc.h
