Method Detail
-
getPosition
public BrickletJoystickV2.Position getPosition() throws TinkerforgeException
Returns the position of the joystick. The middle position of the joystick is x=0, y=0. The returned values are averaged and calibrated (seecalibrate()
). If you want to get the position periodically, it is recommended to use theBrickletJoystickV2.PositionListener
listener and set the period withsetPositionCallbackConfiguration(long, boolean)
.- Throws:
TinkerforgeException
-
isPressed
public boolean isPressed() throws TinkerforgeException
Returns *true* if the button is pressed and *false* otherwise. If you want to get the press-state periodically, it is recommended to use theBrickletJoystickV2.PressedListener
listener and set the period withsetPressedCallbackConfiguration(long, boolean)
.- Throws:
TinkerforgeException
-
calibrate
public void calibrate() throws TinkerforgeException
Calibrates the middle position of the joystick. If your Joystick Bricklet 2.0 does not return x=0 and y=0 in the middle position, call this function while the joystick is standing still in the middle position. The resulting calibration will be saved in non-volatile memory, thus you only have to calibrate it once.- Throws:
TinkerforgeException
-
setPositionCallbackConfiguration
public void setPositionCallbackConfiguration(long period, boolean valueHasToChange) throws TinkerforgeException
The period is the period with which theBrickletJoystickV2.PositionListener
listener is triggered periodically. A value of 0 turns the listener off. If the `value has to change`-parameter is set to true, the listener is only triggered after at least one of the values has changed. If the values didn't change within the period, the listener is triggered immediately on change. If it is set to false, the listener is continuously triggered with the period, independent of the value.- Throws:
TinkerforgeException
-
getPositionCallbackConfiguration
public BrickletJoystickV2.PositionCallbackConfiguration getPositionCallbackConfiguration() throws TinkerforgeException
Returns the listener configuration as set bysetPositionCallbackConfiguration(long, boolean)
.- Throws:
TinkerforgeException
-
setPressedCallbackConfiguration
public void setPressedCallbackConfiguration(long period, boolean valueHasToChange) throws TinkerforgeException
The period is the period with which theBrickletJoystickV2.PressedListener
listener is triggered periodically. A value of 0 turns the listener off. If the `value has to change`-parameter is set to true, the listener is only triggered after at least one of the values has changed. If the values didn't change within the period, the listener is triggered immediately on change. If it is set to false, the listener is continuously triggered with the period, independent of the value.- Throws:
TinkerforgeException
-
getPressedCallbackConfiguration
public BrickletJoystickV2.PressedCallbackConfiguration getPressedCallbackConfiguration() throws TinkerforgeException
Returns the listener configuration as set bysetPressedCallbackConfiguration(long, boolean)
.- Throws:
TinkerforgeException
-
getSPITFPErrorCount
public BrickletJoystickV2.SPITFPErrorCount getSPITFPErrorCount() throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
setBootloaderMode
public int setBootloaderMode(int mode) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
getBootloaderMode
public int getBootloaderMode() throws TinkerforgeException
Returns the current bootloader mode, seesetBootloaderMode(int)
.- Throws:
TinkerforgeException
-
setWriteFirmwarePointer
public void setWriteFirmwarePointer(long pointer) throws TinkerforgeException
Sets the firmware pointer forwriteFirmware(int[])
. 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.- Throws:
TinkerforgeException
-
writeFirmware
public int writeFirmware(int[] data) throws TinkerforgeException
Writes 64 Bytes of firmware at the position as written bysetWriteFirmwarePointer(long)
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.- Throws:
TinkerforgeException
-
setStatusLEDConfig
public void setStatusLEDConfig(int config) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
getStatusLEDConfig
public int getStatusLEDConfig() throws TinkerforgeException
Returns the configuration as set bysetStatusLEDConfig(int)
- Throws:
TinkerforgeException
-
getChipTemperature
public int getChipTemperature() throws TinkerforgeException
Returns the temperature 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.- Throws:
TinkerforgeException
-
reset
public void reset() throws TinkerforgeException
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!- Throws:
TinkerforgeException
-
writeUID
public void writeUID(long uid) throws TinkerforgeException
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.- Throws:
TinkerforgeException
-
readUID
public long readUID() throws TinkerforgeException
Returns the current UID as an integer. Encode as Base58 to get the usual string version.- Throws:
TinkerforgeException
-
getIdentity
public Device.Identity getIdentity() throws TinkerforgeException
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', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an :ref:`Isolator Bricklet <isolator_bricklet>` is always at position 'z'. The device identifier numbers can be found :ref:`here <device_identifier>`. |device_identifier_constant|- Specified by:
