Implementations

impl DualRelayBricklet

pub const DEVICE_IDENTIFIER: u16 = 26u16

pub const DEVICE_DISPLAY_NAME: &'static str = "Dual Relay Bricklet"

pub fn new(uid: Uid, connection: AsyncIpConnection) -> DualRelayBricklet

Creates an object with the unique device ID uid. This object can then be used after the IP Connection ip_connection is connected.

pub fn get_response_expected( &mut self, fun: DualRelayBrickletFunction, ) -> Result<bool, GetResponseExpectedError>

Returns the response expected flag for the function specified by the function ID parameter. It is true if the function is expected to send a response, false otherwise.

For getter functions this is enabled by default and cannot be disabled, because those functions will always send a response. For callback configuration functions it is enabled by default too, but can be disabled by set_response_expected. For setter functions it is disabled by default and can be enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

See set_response_expected for the list of function ID constants available for this function.

pub fn set_response_expected( &mut self, fun: DualRelayBrickletFunction, response_expected: bool, ) -> Result<(), SetResponseExpectedError>

Changes the response expected flag of the function specified by the function ID parameter. This flag can only be changed for setter (default value: false) and callback configuration functions (default value: true). For getter functions it is always enabled.

Enabling the response expected flag for a setter function allows to detect timeouts and other error conditions calls of this setter as well. The device will then send a response for this purpose. If this flag is disabled for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

pub fn set_response_expected_all(&mut self, response_expected: bool)

Changes the response expected flag for all setter and callback configuration functions of this device at once.

pub fn get_api_version(&self) -> [u8; 3]

Returns the version of the API definition (major, minor, revision) implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

pub async fn get_monoflop_done_callback_receiver( &mut self, ) -> impl Stream<Item = MonoflopDoneEvent>

This receiver is triggered whenever a monoflop timer reaches 0. The parameter contain the relay (1 or 2) and the current state of the relay (the state after the monoflop).

pub async fn set_state( &mut self, relay1: bool, relay2: bool, ) -> Result<(), TinkerforgeError>

Sets the state of the relays, true means on and false means off. For example: (true, false) turns relay 1 on and relay 2 off.

If you just want to set one of the relays and don’t know the current state of the other relay, you can get the state with [get_state] or you can use [set_selected_state].

All running monoflop timers will be aborted if this function is called.

pub async fn get_state(&mut self) -> Result<State, TinkerforgeError>

Returns the state of the relays, true means on and false means off.

pub async fn set_monoflop( &mut self, relay: u8, state: bool, time: u32, ) -> Result<(), TinkerforgeError>

The first parameter can be 1 or 2 (relay 1 or relay 2). The second parameter is the desired state of the relay (true means on and false means off). The third parameter indicates the time that the relay should hold the state.

If this function is called with the parameters (1, true, 1500): Relay 1 will turn on and in 1.5s it will turn off again.

A monoflop can be used as a failsafe mechanism. For example: Lets assume you have a RS485 bus and a Dual Relay Bricklet connected to one of the slave stacks. You can now call this function every second, with a time parameter of two seconds. The relay will be on all the time. If now the RS485 connection is lost, the relay will turn off in at most two seconds.

pub async fn get_monoflop( &mut self, relay: u8, ) -> Result<Monoflop, TinkerforgeError>

Returns (for the given relay) the current state and the time as set by [set_monoflop] as well as the remaining time until the state flips.

If the timer is not running currently, the remaining time will be returned as 0.

pub async fn set_selected_state( &mut self, relay: u8, state: bool, ) -> Result<(), TinkerforgeError>

Sets the state of the selected relay (1 or 2), true means on and false means off.

A running monoflop timer for the selected relay will be aborted if this function is called.

The other relay remains untouched.

pub async fn get_identity(&mut self) -> Result<Identity, TinkerforgeError>

Returns the UID, the UID where the Bricklet is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be ‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’ or ‘h’ (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position ‘z’.

The device identifier numbers can be found here. |device_identifier_constant|
