Functions
uint64_t	getTimestamp ()
	Returns the current timer value in microseconds.

Detailed Description

Utility for microsecond timestamp values.

Deprecated

This namespace provided access to sub-millisecond timestamp values for precise timing requirements before Miosix 2.7, since at that time Miosix only had millisecond-accurate tick values. It has now been deprecated in favor of miosix::getTime() which has nanosecond resolution. The class is kept for compatibility reasons and should be removed in the future.

The old timer used a 32bit value and the TIM2 or TIM5 hardware peripherals, at a frequency of 250KHz. This way the timer had a resolution of 4us, it would overflow after 4.7 hours and only required a 2-bit shift left operation to convert from counter tick to microseconds.
