Function Documentation

LED_Blink()

void LED_Blink	(	uint32_t	Hdelay,
		uint32_t	Ldelay
	)

Blink LED with specified timing.

Parameters

[in]	on_ticks	Duration LED is on (in OS ticks)
[in]	off_ticks	Duration LED is off (in OS ticks)

Note

Uses task_active_sleep() - must be called from task context

Blink LED with specified timing.

Turns LED on for specified duration, then off for specified duration. Uses task_active_sleep() for non-blocking delays.

Parameters

[in]	Hdelay	LED on duration in OS ticks
[in]	Ldelay	LED off duration in OS ticks

Precondition

GPIO must be initialized (MX_GPIO_Init called)

Must be called from task context (uses task_active_sleep)

Note

Total blink period = Hdelay + Ldelay ticks
