Defragster	b60d6774ac	Use ARM Synchronization for micros() Use: ARM Synchronization Primitives, include of arm_math.h Get systick_isr data safely without disable interrupts, uses systick_safe_read as indicator variable	vor 5 Jahren
Defragster	8cb4de3469	expose ccmicros for testing micros() unchanged - minor systick_isr() diversion - one line added to systick_isr.	vor 5 Jahren
Defragster	c4c5a0170f	opps - left in compared code	vor 5 Jahren
Defragster	edbf0b4c0c	Confirm no systick_isr() interruption This saves a cycle - and checks both values to avoid _isr change of either value based on code/execution	vor 5 Jahren
Defragster	6ba4fe8e3d	Replace micros for one using CycCnt Alternate micros() extends millis() using ARM_DWT_CYCCNT > Also makes unused_interrupt_vector() weak to allow user override like Teensy3	vor 5 Jahren
