Tinkerforge::BrickletSegmentDisplay4x7V2 - Four 7-segment displays with switchable dots
This constant is used to identify a Segment Display 4x7 Bricklet 2.0.
The get_identity() subroutine and the CALLBACK_ENUMERATE callback of the IP Connection have a device_identifier parameter to specify the Brick's or Bricklet's type.
This constant represents the display name of a Segment Display 4x7 Bricklet 2.0.
This constant is used with the register_callback() subroutine to specify the CALLBACK_COUNTER_FINISHED callback.
This constant is used with the get_response_expected(), set_response_expected() and set_response_expected_all() subroutines.
Creates an object with the unique device ID *uid* and adds it to the IP Connection *ipcon*.
Sets the segments of the Segment Display 4x7 Bricklet 2.0 segment-by-segment.
The data is split into the four digits, two colon dots and the tick mark.
The indices of the segments in the digit and colon parameters are as follows:
.. image:: /Images/Bricklets/bricklet_segment_display_4x7_v2_segment_index.png :scale: 100 % :alt: Indices of segments :align: center
Returns the segment data as set by :func:`Set Segments`.
The brightness can be set between 0 (dark) and 7 (bright).
The default value is 7.
Returns the brightness as set by :func:`Set Brightness`.
Sets a numeric value for each of the digits. The values can be between -2 and 15. They represent:
* -2: minus sign * -1: blank * 0-9: 0-9 * 10: A * 11: b * 12: C * 13: d * 14: E * 15: F
Example: A call with [-2, -1, 4, 2] will result in a display of "- 42".
Turns one specified segment on or off.
The indices of the segments are as follows:
.. image:: /Images/Bricklets/bricklet_segment_display_4x7_v2_selected_segment_index.png :scale: 100 % :alt: Indices of selected segments :align: center
Returns the value of a single segment.
Starts a counter with the *from* value that counts to the *to* value with the each step incremented by *increment*. The *length* of the increment is given in ms.
Example: If you set *from* to 0, *to* to 100, *increment* to 1 and *length* to 1000, a counter that goes from 0 to 100 with one second pause between each increment will be started.
The maximum values for *from*, *to* and *increment* is 9999, the minimum value is -999.
Using a negative *increment* allows to count backwards.
You can stop the counter at every time by calling :func:`Set Segments` or :func:`Set Numeric Value`.
Returns the counter value that is currently shown on the display.
If there is no counter running a 0 will be returned.
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.
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.
Returns the current bootloader mode, see :func:`Set Bootloader Mode`.
Sets the firmware pointer for :func:`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).
Writes 64 Bytes of firmware at the position as written by :func:`Set Write Firmware Pointer` before. The firmware is written to flash every 4 chunks.
You can only write firmware in bootloader mode.
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.
Returns the configuration as set by :func:`Set Status LED Config`
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.
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!
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.
Returns the current UID as an integer. Encode as Base58 to get the usual string version.
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 :ref:`here <device_identifier>`. |device_identifier_constant|
