Hardware timers
The ESP8266 has one of these, HardwareTimer
, which can be programmed to trigger
when a pre-programmed interval has elapsed. The callback handler is executed in an
interrupt context so is restricted on what it can do.
The timer is appropriate where accurate and short timing is required.
The API for hardware (and Software timer queues timers) is identical, implemented using a
CallbackTimer
class template for best performance.
- group hardware_timer
Hardware callback timer.
Typedefs
-
template<hw_timer_clkdiv_t clkdiv = TIMER_CLKDIV_16, HardwareTimerMode mode = eHWT_NonMaskable>
using HardwareTimer1 = CallbackTimer<Timer1Api<clkdiv, mode>> Hardware Timer class template with selectable divider and interrupt mode.
-
using HardwareTimer = HardwareTimer1<>
Default hardware Timer class.
Enums
-
template<hw_timer_clkdiv_t clkdiv, HardwareTimerMode mode>
class Timer1Api : public CallbackTimerApi<Timer1Api<clkdiv, mode>> - #include <HardwareTimer.h>
Class template for Timer1 API.
Note
Provides low-level interface for timer access
