rik te winkel / mbed-dev

Forked mbed-dev as I use an 20 pins stm32F042 and not the 32 pins version

Dependents:   Numitron_clock

Fork of mbed-dev by mbed official

targets/hal/TARGET_STM/TARGET_STM32F2/sleep.c@144:ef7eb2e8f9f7 
This updates the lib to the mbed lib v128



NOTE: This release includes a restructuring of the file and directory locations and thus some

include paths in your code may need updating accordingly.
