Detailed Description

Access Hardware timer.

Macro Definition Documentation

#define MAX_HW_TIMER_INTERVAL_US   0x7fffff

Maximum timer interval in microseconds.

#define MIN_HW_TIMER_INTERVAL_US   0x32

Minimum hardware interval in microseconds.

Function Documentation

uint32_t IRAM_ATTR timerTicksToUs

(

uint32_t

ticks

)

Convert timer ticks into microseconds.

Note

accounts for current timer prescale setting

uint32_t IRAM_ATTR usToTimerTicks

(

uint32_t

us

)

Convert microseconds into timer ticks.

Note

Replaces the previous US_TO_RTC_TIMER_TICKS macro to guarantee we use the correct timer prescale value.
