Jim Paris / mbed-dev-STM32L151RB

Fork of mbed-dev with the NUCLEO-L152RE target modified for use with the STM32L151RB (128 kB flash, 16 kB RAM).

Fork of mbed-dev by mbed official

To use this, remove the default "mbed" library and import this one instead. Target must be NUCLEO_L152RE.

Commit message:
Use TIM9 instead of TIM5

STM32L151xB doesn't have TIM5. TIM9 is 16-bit instead of 32-bit, but
should still work OK.
