sourceimpl DualButtonV2Bricklet
impl DualButtonV2Bricklet
pub const DEVICE_IDENTIFIER: u16 = 2_119u16
pub const DEVICE_DISPLAY_NAME: &'static str = "Dual Button Bricklet 2.0"
sourcepub fn new(uid: &str, ip_connection: &IpConnection) -> DualButtonV2Bricklet
pub fn new(uid: &str, ip_connection: &IpConnection) -> DualButtonV2Bricklet
Creates an object with the unique device ID uid
. This object can then be used after the IP Connection ip_connection
is connected.
sourcepub fn get_response_expected(
&mut self,
fun: DualButtonV2BrickletFunction
) -> Result<bool, GetResponseExpectedError>
pub fn get_response_expected(
&mut self,
fun: DualButtonV2BrickletFunction
) -> 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 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.
sourcepub fn set_response_expected(
&mut self,
fun: DualButtonV2BrickletFunction,
response_expected: bool
) -> Result<(), SetResponseExpectedError>
pub fn set_response_expected(
&mut self,
fun: DualButtonV2BrickletFunction,
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 send and errors are silently ignored, because they cannot be detected.
sourcepub fn set_response_expected_all(&mut self, response_expected: bool)
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.
sourcepub fn get_state_changed_callback_receiver(
&self
) -> ConvertingCallbackReceiver<StateChangedEvent>
pub fn get_state_changed_callback_receiver(
&self
) -> ConvertingCallbackReceiver<StateChangedEvent>
This receiver is called whenever a button is pressed.
Possible states for buttons are:
- 0 = pressed
- 1 = released
Possible states for LEDs are:
- 0 = AutoToggleOn: Auto toggle enabled and LED on.
- 1 = AutoToggleOff: Auto toggle enabled and LED off.
- 2 = On: LED on (auto toggle is disabled).
- 3 = Off: LED off (auto toggle is disabled).
This receiver can be enabled with Set State Changed Receiver Configuration
.
sourcepub fn set_led_state(&self, led_l: u8, led_r: u8) -> ConvertingReceiver<()>
pub fn set_led_state(&self, led_l: u8, led_r: u8) -> ConvertingReceiver<()>
Sets the state of the LEDs. Possible states are:
- 0 = AutoToggleOn: Enables auto toggle with initially enabled LED.
- 1 = AutoToggleOff: Activates auto toggle with initially disabled LED.
- 2 = On: Enables LED (auto toggle is disabled).
- 3 = Off: Disables LED (auto toggle is disabled).
In auto toggle mode the LED is toggled automatically at each press of a button.
If you just want to set one of the LEDs and don’t know the current state
of the other LED, you can get the state with Get LED State
or you
can use Set Selected LED State
.
The default value is (1, 1).

sourcepub fn set_state_changed_callback_configuration(
&self,
enabled: bool
) -> ConvertingReceiver<()>
pub fn set_state_changed_callback_configuration(
&self,
enabled: bool
) -> ConvertingReceiver<()>
If you enable this receiver, the get_state_changed_callback_receiver
receiver is triggered
every time a button is pressed/released
By default this receiver is disabled.
sourcepub fn get_state_changed_callback_configuration(
&self
) -> ConvertingReceiver<bool>
pub fn get_state_changed_callback_configuration(
&self
) -> ConvertingReceiver<bool>
Returns the configuration as set by Set State Changed Receiver Configuration
.
sourcepub fn get_spitfp_error_count(&self) -> ConvertingReceiver<SpitfpErrorCount>
pub fn get_spitfp_error_count(&self) -> ConvertingReceiver<SpitfpErrorCount>
Returns the error count for the communication between Brick and Bricklet.
The errors are divided into
- ACK checksum errors,
- message checksum errors,
- framing errors and
- overflow errors.
The errors counts are for errors that occur on the Bricklet side. All Bricks have a similar function that returns the errors on the Brick side.
sourcepub fn set_bootloader_mode(&self, mode: u8) -> ConvertingReceiver<u8>
pub fn set_bootloader_mode(&self, mode: u8) -> ConvertingReceiver<u8>
Sets the bootloader mode and returns the status after the requested mode change was instigated.
You can change from bootloader mode to firmware mode and vice versa. A change from bootloader mode to firmware mode will only take place if the entry function, device identifier and CRC are present and correct.
This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.

sourcepub fn set_write_firmware_pointer(&self, pointer: u32) -> ConvertingReceiver<()>
pub fn set_write_firmware_pointer(&self, pointer: u32) -> ConvertingReceiver<()>
Sets the firmware pointer for Write Firmware
. The pointer has
to be increased by chunks of size 64. The data is written to flash
every 4 chunks (which equals to one page of size 256).
This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.
sourcepub fn write_firmware(&self, data: [u8; 64]) -> ConvertingReceiver<u8>
pub fn write_firmware(&self, data: [u8; 64]) -> ConvertingReceiver<u8>
Writes 64 Bytes of firmware at the position as written by
Set Write Firmware Pointer
before. The firmware is written
to flash every 4 chunks.
You can only write firmware in bootloader mode.
This function is used by Brick Viewer during flashing. It should not be necessary to call it in a normal user program.
sourcepub fn set_status_led_config(&self, config: u8) -> ConvertingReceiver<()>
pub fn set_status_led_config(&self, config: u8) -> ConvertingReceiver<()>
Sets the status LED configuration. By default the LED shows communication traffic between Brick and Bricklet, it flickers once for every 10 received data packets.
You can also turn the LED permanently on/off or show a heartbeat.
If the Bricklet is in bootloader mode, the LED is will show heartbeat by default.
Associated constants:
- DUAL_BUTTON_V2BRICKLET_STATUS_LED_CONFIG_OFF
- DUAL_BUTTON_V2BRICKLET_STATUS_LED_CONFIG_ON
- DUAL_BUTTON_V2BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT

sourcepub fn get_chip_temperature(&self) -> ConvertingReceiver<i16>
pub fn get_chip_temperature(&self) -> ConvertingReceiver<i16>
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.
sourcepub fn reset(&self) -> ConvertingReceiver<()>
pub fn reset(&self) -> ConvertingReceiver<()>
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!
sourcepub fn write_uid(&self, uid: u32) -> ConvertingReceiver<()>
pub fn write_uid(&self, uid: u32) -> ConvertingReceiver<()>
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.
sourcepub fn read_uid(&self) -> ConvertingReceiver<u32>
pub fn read_uid(&self) -> ConvertingReceiver<u32>
Returns the current UID as an integer. Encode as Base58 to get the usual string version.
sourcepub fn get_identity(&self) -> ConvertingReceiver<Identity>
pub fn get_identity(&self) -> ConvertingReceiver<Identity>
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|
