Functions
uint32_t IRAM_ATTR	irMicros (void)
	Microseconds since boot. Wraps every ~71.6 minutes.

uint32_t	irMillis (void)
	Milliseconds since boot. Wraps every ~49.7 days, like Arduino's millis().

void IRAM_ATTR	irDelayUs (uint32_t usec)
	Busy-wait. Accurate, but blocks the core it runs on.

void	irDelayMs (uint32_t msec)
	Sleep, yielding the CPU to other FreeRTOS tasks.

void	irYield (void)
	Feed the task watchdog without giving up the CPU for long.

bool	irGpioOutput (uint16_t pin)
	Configure a GPIO as a push-pull output.

bool	irGpioInput (uint16_t pin, bool pullup)
	Configure a GPIO as an input, optionally with the internal pull-up.

void IRAM_ATTR	irGpioWrite (uint16_t pin, uint8_t level)
	Set the level of an output GPIO.

uint8_t IRAM_ATTR	irGpioRead (uint16_t pin)
	Read the level of a GPIO.

void	irRestart (void)
	Reboot the chip. Used when a buffer allocation fails.

void	irDebugPrint (const char *str)

void	irDebugPrint (const String &str)

void	irDebugPrint (char c)

void	irDebugPrint (uint64_t value)

void	irDebugPrint (int64_t value)
