Browse Source 
Adding files for STM32F1 HAL based on libmaple/stm32duino core.
Current persistent_store uses cardreader changes to be sent in separate
commit, but could be changed to use i2c eeprom.

* NOTE: By default libmaple sets ARPE = 1, which means the Auto reload register is preloaded (will only update with an update event)
* Thus we have to pause the timer, update the value, refresh, resume the timer.
* That seems like a big waste of time and may be better to change the timer config to ARPE = 0, so ARR can be updated any time.
* We are using a Channel in each timer in Capture/Compare mode. We could also instead use the Time Update Event Interrupt, but need to disable ARPE
* so we can change the ARR value on the fly (without calling refresh), and not get an interrupt right there because we caused an UEV.
* This mode pretty much makes 2 timers unusable for PWM since they have their counts updated all the time on ISRs.
* The way Marlin manages timer interrupts doesn't make for an efficient usage in STM32F1
* Todo: Look at that possibility later.

# This HAL is for STM32F103 boards used with libmaple/stm32duino Arduino core.
# This HAL is in development and has not been tested with an actual printer.
### The stm32 core needs a modification in the file util.h to avoid conflict with Marlin macros for Debug.
Since only 1 file needs change in the stm32duino core, it's preferable over making changes to Marlin.
After these lines:
<>
#else
#define ASSERT_FAULT(exp) (void)((0))
#endif
<>
Add the following 3 lines:
<>
#undef DEBUG_NONE
#undef DEBUG_FAULT
#undef DEBUG_ALL
<>
### Main developers:
Victorpv
### Most up to date repository for this HAL:
https://github.com/victorpv/Marlin/tree/bugfix-2.0.x
PRs should be first sent to that fork, and once tested merged to Marlin bugfix-2.0.x branch.
