dshot_edt_bind()

void dshot_edt_bind	(	dshot_edt_t *	e,
		uint32_t	now_ms )

A new binding: nothing asked, nothing heard, an ask due at once.

Parameters

e	Ask state to bind.
now_ms	Current time, in milliseconds.

dshot_edt_frame()

bool dshot_edt_frame	(	dshot_edt_t *	e,
		bool	stopped,
		uint32_t	now_ms )

Whether the frame about to go out is a repeat of DSHOT_CMD_EDT_ENABLE.

stopped says the throttle this frame would carry is zero. False means send the throttle.

Parameters

e	Ask state.
stopped	true when the throttle this frame would carry is zero.
now_ms	Current time, in milliseconds.

Returns

true when the frame is a repeat of the ask.

dshot_edt_heard()

void dshot_edt_heard	(	dshot_edt_t *	e,
		dshot_telem_kind_t	kind )

A reply arrived; an extended kind after an ask ends the asking.

Parameters

e	Ask state.
kind	Kind of the reply that arrived.

dshot_edt_idle()

void dshot_edt_idle	(	dshot_edt_t *	e,
		uint32_t	now_ms )

Not driving: the next run owes the ask again, due from its first frame.

Called on every service while disarmed, so it is idempotent; asked is kept.

Parameters

e	Ask state.
now_ms	Current time, in milliseconds.
