CALLBACK_PULSE_PER_SECOND =

This callback is triggered precisely once per second, see ‘PPS <en.wikipedia.org/wiki/Pulse-per-second_signal>`__.

The precision of two subsequent pulses will be skewed because of the latency in the USB/RS485/Ethernet connection. But in the long run this will be very precise. For example a count of 3600 pulses will take exactly 1 hour.

21
CALLBACK_COORDINATES =

This callback is triggered periodically with the period that is set by BrickletGPSV2#set_coordinates_callback_period. The parameters are the same as for BrickletGPSV2#get_coordinates.

The CALLBACK_COORDINATES callback is only triggered if the coordinates changed since the last triggering and if there is currently a fix as indicated by BrickletGPSV2#get_status.

22
CALLBACK_STATUS =

This callback is triggered periodically with the period that is set by BrickletGPSV2#set_status_callback_period. The parameters are the same as for BrickletGPSV2#get_status.

The CALLBACK_STATUS callback is only triggered if the status changed since the last triggering.

23
CALLBACK_ALTITUDE =

This callback is triggered periodically with the period that is set by BrickletGPSV2#set_altitude_callback_period. The parameters are the same as for BrickletGPSV2#get_altitude.

The CALLBACK_ALTITUDE callback is only triggered if the altitude changed since the last triggering and if there is currently a fix as indicated by BrickletGPSV2#get_status.

24
CALLBACK_MOTION =

This callback is triggered periodically with the period that is set by BrickletGPSV2#set_motion_callback_period. The parameters are the same as for BrickletGPSV2#get_motion.

The CALLBACK_MOTION callback is only triggered if the motion changed since the last triggering and if there is currently a fix as indicated by BrickletGPSV2#get_status.

25
CALLBACK_DATE_TIME =

This callback is triggered periodically with the period that is set by BrickletGPSV2#set_date_time_callback_period. The parameters are the same as for BrickletGPSV2#get_date_time.

The CALLBACK_DATE_TIME callback is only triggered if the date or time changed since the last triggering.

Returns the GPS coordinates. Latitude and longitude are given in the “DD.dddddd°“ format, the value 57123468 means 57.123468°. The parameter “ns“ and “ew“ are the cardinal directions for latitude and longitude. Possible values for “ns“ and “ew“ are ‘N’, ‘S’, ‘E’ and ‘W’ (north, south, east and west).

#get_motion ⇒ Object

Returns the current course and speed. A course of 0° means the Bricklet is traveling north bound and 90° means it is traveling east bound.

Please note that this only returns useful values if an actual movement is present.

#get_spitfp_error_count ⇒ Object

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.

#set_bootloader_mode(mode) ⇒ Object

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.

#set_date_time_callback_period(period) ⇒ Object

Sets the period with which the CALLBACK_DATE_TIME callback is triggered periodically. A value of 0 turns the callback off.

The CALLBACK_DATE_TIME callback is only triggered if the date or time changed since the last triggering.

#set_fix_led_config(config) ⇒ Object

Sets the fix LED configuration. By default the LED shows if the Bricklet got a GPS fix yet. If a fix is established the LED turns on. If there is no fix then the LED is turned off.

You can also turn the LED permanently on/off, show a heartbeat or let it blink in sync with the PPS (pulse per second) output of the GPS module.

If the Bricklet is in bootloader mode, the LED is off.

#set_sbas_config(sbas_config) ⇒ Object

If ‘SBAS <en.wikipedia.org/wiki/GNSS_augmentation#Satellite-based_augmentation_system>`__ is enabled, the position accuracy increases (if SBAS satellites are in view), but the update rate is limited to 5Hz. With SBAS disabled the update rate is increased to 10Hz.

#set_status_led_config(config) ⇒ Object

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.

#set_write_firmware_pointer(pointer) ⇒ Object

Sets the firmware pointer for BrickletGPSV2#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.

#write_firmware(data) ⇒ Object

Writes 64 Bytes of firmware at the position as written by BrickletGPSV2#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.

#write_uid(uid) ⇒ Object

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.
