Methods

impl Rs485Bricklet[src]

pub const DEVICE_IDENTIFIER: u16[src]

pub const DEVICE_DISPLAY_NAME: &'static str[src]

pub fn new<T: GetRequestSender>(uid: &str, req_sender: T) -> Rs485Bricklet[src]

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: Rs485BrickletFunction
) -> Result<bool, GetResponseExpectedError>[src]

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 send 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: Rs485BrickletFunction,
    response_expected: bool
) -> Result<(), SetResponseExpectedError>[src]

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 send and errors are silently ignored, because they cannot be detected.

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

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][src]

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 fn get_chip_temperature(&self) -> ConvertingReceiver<i16>[src]

Returns the temperature in °C as measured inside the microcontroller. The value returned is not the ambient temperature!

The temperature is only proportional to the real temperature and it has bad accuracy. Practically it is only useful as an indicator for temperature changes.

pub fn reset(&self) -> ConvertingReceiver<()>[src]

Calling this function will reset the Bricklet. All configurations will be lost.

After a reset you have to create new device objects, calling functions on the existing ones will result in undefined behavior!

pub fn write_uid(&self, uid: u32) -> ConvertingReceiver<()>[src]

Writes a new UID into flash. If you want to set a new UID you have to decode the Base58 encoded UID string into an integer first.

We recommend that you use Brick Viewer to change the UID.

pub fn read_uid(&self) -> ConvertingReceiver<u32>[src]

Returns the current UID as an integer. Encode as Base58 to get the usual string version.

pub fn get_identity(&self) -> ConvertingReceiver<Identity>[src]

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' or 'd'.

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