F_CPU_MHZ

#define F_CPU_MHZ   (GET_CPU_FREQUENCY() / 1000000L)

CPU speed, in megahertz (MHz) - compile-time constant Uses GET_CPU_FREQUENCY() from platforms/cpu_frequency.h which provides a compile-time constant value, avoiding issues with platforms like STM32duino where F_CPU may be defined as a runtime variable (SystemCoreClock)
