Implementations

impl MotionDetectorV2Bricklet

pub const DEVICE_IDENTIFIER: u16 = 292u16

pub const DEVICE_DISPLAY_NAME: &'static str = "Motion Detector Bricklet 2.0"

pub fn new(uid: &str, ip_connection: &IpConnection) -> MotionDetectorV2Bricklet

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: MotionDetectorV2BrickletFunction
) -> 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.

pub fn set_response_expected(
    &mut self,
    fun: MotionDetectorV2BrickletFunction,
    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.

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_motion_detected_callback_receiver(
    &self
) -> ConvertingCallbackReceiver<()>

This receiver is called after a motion was detected.

pub fn get_detection_cycle_ended_callback_receiver(
    &self
) -> ConvertingCallbackReceiver<()>

This receiver is called when the detection cycle ended. When this receiver is called, a new motion can be detected again after approximately 2 seconds.

pub fn get_motion_detected(&self) -> ConvertingReceiver<u8>

Returns 1 if a motion was detected. How long this returns 1 after a motion was detected can be adjusted with one of the small potentiometers on the Motion Detector Bricklet, see here <motion_detector_bricklet_sensitivity_delay_block_time>.

There is also a blue LED on the Bricklet that is on as long as the Bricklet is in the motion detected state.

Associated constants:

• MOTION_DETECTOR_V2BRICKLET_MOTION_NOT_DETECTED
• MOTION_DETECTOR_V2BRICKLET_MOTION_DETECTED

pub fn set_sensitivity(&self, sensitivity: u8) -> ConvertingReceiver<()>

Sets the sensitivity of the PIR sensor. The range is 0-100. At full sensitivity (100), the Bricklet can detect motion in a range of approximately 12m.

The actual range depends on many things in the environment (e.g. reflections) and the size of the object to be detected. While a big person might be detected in a range of 10m a cat may only be detected at 2m distance with the same setting.

So you will have to find a good sensitivity for your application by trial and error.

The default value is 50.

pub fn get_sensitivity(&self) -> ConvertingReceiver<u8>

Returns the sensitivity as set by Set Sensitivity.

pub fn set_indicator(
    &self,
    top_left: u8,
    top_right: u8,
    bottom: u8
) -> ConvertingReceiver<()>

Sets the blue backlight of the fresnel lens. The backlight consists of three LEDs. The brightness of each LED can be controlled with a 8-bit value (0-255). A value of 0 turns the LED off and a value of 255 turns the LED to full brightness.

The default value is 0, 0, 0.

pub fn get_indicator(&self) -> ConvertingReceiver<Indicator>

Returns the indicator configuration as set by Set Indicator.

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.

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.

• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_BOOTLOADER
• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_FIRMWARE
• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT

pub fn get_bootloader_mode(&self) -> ConvertingReceiver<u8>

Returns the current bootloader mode, see Set Bootloader Mode.

Associated constants:

• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_BOOTLOADER
• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_FIRMWARE
• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT
• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT
• MOTION_DETECTOR_V2BRICKLET_BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT

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.

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.

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:

• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_OFF
• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_ON
• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT
• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_SHOW_STATUS

pub fn get_status_led_config(&self) -> ConvertingReceiver<u8>

Returns the configuration as set by Set Status LED Config

Associated constants:

• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_OFF
• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_ON
• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_SHOW_HEARTBEAT
• MOTION_DETECTOR_V2BRICKLET_STATUS_LED_CONFIG_SHOW_STATUS

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.

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!

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.

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

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

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|
