API

Generally, every method of the C# bindings that returns a value can throw a Tinkerforge.TimeoutException. This exception gets thrown if the device did not respond. If a cable based connection is used, it is unlikely that this exception gets thrown (assuming nobody plugs the device out). However, if a wireless connection is used, timeouts will occur if the distance to the device gets too big.

Since C# does not support multiple return values directly, we use the out keyword to return multiple values from a method.

The namespace for all Brick/Bricklet bindings and the IPConnection is Tinkerforge.*.

All methods listed below are thread-safe.

Basic Functions

class BrickletIndustrialDigitalIn4V2(string uid, IPConnection ipcon)
Parameters:
  • uid – Type: string
  • ipcon – Type: IPConnection
Returns:

Creates an object with the unique device ID uid:

BrickletIndustrialDigitalIn4V2 industrialDigitalIn4V2 = new BrickletIndustrialDigitalIn4V2("YOUR_DEVICE_UID", ipcon);

This object can then be used after the IP Connection is connected.

bool[] BrickletIndustrialDigitalIn4V2.GetValue()
Returns:
  • value – Type: bool[], Length: 4

Returns the input value as bools, true refers to high and false refers to low.

void BrickletIndustrialDigitalIn4V2.SetChannelLEDConfig(byte channel, byte config)
Parameters:
  • channel – Type: byte, Range: See constants
  • config – Type: byte, Range: See constants, Default: 3

Each channel has a corresponding LED. You can turn the LED off, on or show a heartbeat. You can also set the LED to "Channel Status". In this mode the LED is on if the channel is high and off otherwise.

By default all channel LEDs are configured as "Channel Status".

  • resetCounter – Type: bool
Returns:
  • count – Type: long, Range: [0 to 232 - 1]

Returns the current value of the edge counter for the selected channel. You can configure the edges that are counted with SetEdgeCountConfiguration().

If you set the reset counter to true, the count is set back to 0 directly after it is read.

The following constants are available for this function:

For channel:

  • BrickletIndustrialDigitalIn4V2.CHANNEL_0 = 0
  • BrickletIndustrialDigitalIn4V2.CHANNEL_1 = 1

  • channel – Type: byte, Range: See constants
  • edgeType – Type: byte, Range: See constants, Default: 0
  • debounce – Type: byte, Unit: 1 ms, Range: [0 to 255], Default: 100

Configures the edge counter for a specific channel.

The edge type parameter configures if rising edges, falling edges or both are counted. Possible edge types are:

  • 0 = rising
  • 1 = falling
  • 2 = both

Configuring an edge counter resets its value to 0.

If you don't know what any of this means, just leave it at default. The default configuration is very likely OK for you.

Returns:
  • temperature – Type: short, Unit: 1 °C, Range: [-215 to 215 - 1]

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.

void BrickletIndustrialDigitalIn4V2.Reset()

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!

void BrickletIndustrialDigitalIn4V2.GetIdentity(out string uid, out string connectedUid, out char position, out byte[] hardwareVersion, out byte[] firmwareVersion, out int deviceIdentifier)
Output Parameters:
  • uid – Type: string, Length: up to 8

The position can be 'a', 'b', 'c', 'd', 'e', 'f', 'g' or 'h' (Bricklet Port). A Bricklet connected to an Isolator Bricklet is always at position 'z'.

The device identifier numbers can be found here. There is also a constant for the device identifier of this Bricklet.

Callback Configuration Functions

void BrickletIndustrialDigitalIn4V2.SetValueCallbackConfiguration(byte channel, long period, bool valueHasToChange)
Parameters:
  • channel – Type: byte, Range: See constants
  • period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • valueHasToChange – Type: bool, Default: false

This callback can be configured per channel.

The period is the period with which the ValueCallback callback is triggered periodically. A value of 0 turns the callback off.

If the value has to change-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

The following constants are available for this function:

For channel:

  • BrickletIndustrialDigitalIn4V2.CHANNEL_0 = 0
  • BrickletIndustrialDigitalIn4V2.CHANNEL_1 = 1
  • BrickletIndustrialDigitalIn4V2.CHANNEL_2 = 2
  • BrickletIndustrialDigitalIn4V2.CHANNEL_3 = 3
void BrickletIndustrialDigitalIn4V2.GetValueCallbackConfiguration(byte channel, out long period, out bool valueHasToChange)
Parameters:
  • channel – Type: byte, Range: See constants
Output Parameters:
  • period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • valueHasToChange – Type: bool, Default: false

Returns the callback configuration for the given channel as set by SetValueCallbackConfiguration().

The following constants are available for this function:

For channel:

  • BrickletIndustrialDigitalIn4V2.CHANNEL_0 = 0
  • BrickletIndustrialDigitalIn4V2.CHANNEL_1 = 1
  • BrickletIndustrialDigitalIn4V2.CHANNEL_2 = 2
  • BrickletIndustrialDigitalIn4V2.CHANNEL_3 = 3
void BrickletIndustrialDigitalIn4V2.SetAllValueCallbackConfiguration(long period, bool valueHasToChange)
Parameters:
  • period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • valueHasToChange – Type: bool, Default: false

The period is the period with which the AllValueCallback callback is triggered periodically. A value of 0 turns the callback off.

If the value has to change-parameter is set to true, the callback is only triggered after the value has changed. If the value didn't change within the period, the callback is triggered immediately on change.

If it is set to false, the callback is continuously triggered with the period, independent of the value.

void BrickletIndustrialDigitalIn4V2.GetAllValueCallbackConfiguration(out long period, out bool valueHasToChange)
Output Parameters:
  • period – Type: long, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • valueHasToChange – Type: bool, Default: false

Returns the callback configuration as set by SetAllValueCallbackConfiguration().

Callbacks

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done by appending your callback handler to the corresponding event:

void MyCallback(BrickletIndustrialDigitalIn4V2 sender, int value)
{
    System.Console.WriteLine("Value: " + value);
}

industrialDigitalIn4V2.ExampleCallback += MyCallback;

The available events are described below.

Note

Using callbacks for recurring events is always preferred compared to using getters. It will use less USB bandwidth and the latency will be a lot better, since there is no round trip time.

event BrickletIndustrialDigitalIn4V2.ValueCallback(BrickletIndustrialDigitalIn4V2 sender, byte channel, bool changed, bool value)
Callback Parameters:
  • sender – Type: BrickletIndustrialDigitalIn4V2
  • channel – Type: byte, Range: See constants
  • changed – Type: bool
  • value – Type: bool

This callback is triggered periodically according to the configuration set by SetValueCallbackConfiguration().

The parameters are the channel, a value-changed indicator and the actual value for the channel. The changed parameter is true if the value has changed since the last callback.

The following constants are available for this function:

For channel:

  • BrickletIndustrialDigitalIn4V2.CHANNEL_0 = 0
  • BrickletIndustrialDigitalIn4V2.CHANNEL_1 = 1
  • BrickletIndustrialDigitalIn4V2.CHANNEL_2 = 2
  • BrickletIndustrialDigitalIn4V2.CHANNEL_3 = 3
event BrickletIndustrialDigitalIn4V2.AllValueCallback(BrickletIndustrialDigitalIn4V2 sender, bool[] changed, bool[] value)
Callback Parameters:
  • sender – Type: BrickletIndustrialDigitalIn4V2
  • changed – Type: bool[], Length: 4
  • value – Type: bool[], Length: 4

This callback is triggered periodically according to the configuration set by SetAllValueCallbackConfiguration().

The parameters are the same as GetValue(). Additional the changed parameter is true if the value has changed since the last callback.

Virtual Functions

Virtual functions don't communicate with the device itself, but operate only on the API bindings device object. They can be called without the corresponding IP Connection object being connected.

byte[] BrickletIndustrialDigitalIn4V2.GetAPIVersion()
Output Parameters:
  • apiVersion – Type: byte[], Length: 3
    • 0: major – Type: byte, Range: [0 to 255]
    • 1: minor – Type: byte, Range: [0 to 255]
    • 2: revision – Type: byte, Range: [0 to 255]

Returns the version of the API definition implemented by this API bindings. This is neither the release version of this API bindings nor does it tell you anything about the represented Brick or Bricklet.

bool BrickletIndustrialDigitalIn4V2.GetResponseExpected(byte functionId)
Parameters:
  • functionId – Type: byte, Range: See constants
Returns:
  • responseExpected – Type: bool

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 SetResponseExpected(). 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 sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_VALUE_CALLBACK_CONFIGURATION = 2
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_ALL_VALUE_CALLBACK_CONFIGURATION = 4
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_EDGE_COUNT_CONFIGURATION = 7
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_CHANNEL_LED_CONFIG = 9
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_STATUS_LED_CONFIG = 239
  • BrickletIndustrialDigitalIn4V2.FUNCTION_RESET = 243
  • BrickletIndustrialDigitalIn4V2.FUNCTION_WRITE_UID = 248
void BrickletIndustrialDigitalIn4V2.SetResponseExpected(byte functionId, bool responseExpected)
Parameters:
  • functionId – Type: byte, Range: See constants
  • responseExpected – Type: bool

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 sent and errors are silently ignored, because they cannot be detected.

The following constants are available for this function:

For functionId:

  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_VALUE_CALLBACK_CONFIGURATION = 2
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_ALL_VALUE_CALLBACK_CONFIGURATION = 4
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_EDGE_COUNT_CONFIGURATION = 7
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_CHANNEL_LED_CONFIG = 9
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_WRITE_FIRMWARE_POINTER = 237
  • BrickletIndustrialDigitalIn4V2.FUNCTION_SET_STATUS_LED_CONFIG = 239
  • BrickletIndustrialDigitalIn4V2.FUNCTION_RESET = 243
  • BrickletIndustrialDigitalIn4V2.FUNCTION_WRITE_UID = 248
void BrickletIndustrialDigitalIn4V2.SetResponseExpectedAll(bool responseExpected)
Parameters:
  • responseExpected – Type: bool

Changes the response expected flag for all setter and callback configuration functions of this device at once.

Internal Functions

Internal functions are used for maintenance tasks such as flashing a new firmware of changing the UID of a Bricklet. These task should be performed using Brick Viewer instead of using the internal functions directly.

byte BrickletIndustrialDigitalIn4V2.SetBootloaderMode(byte mode)
Parameters:
  • mode – Type: byte, Range: See constants
Returns:
  • status – Type: byte, Range: See constants

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.

The following constants are available for this function:

For mode:

  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_BOOTLOADER = 0
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_FIRMWARE = 1
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4

For status:

  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_STATUS_OK = 0

byte BrickletIndustrialDigitalIn4V2.GetBootloaderMode()
Returns:
  • mode – Type: byte, Range: See constants

Returns the current bootloader mode, see SetBootloaderMode().

The following constants are available for this function:

For mode:

  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_BOOTLOADER = 0
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_FIRMWARE = 1
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_BOOTLOADER_WAIT_FOR_REBOOT = 2
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_REBOOT = 3
  • BrickletIndustrialDigitalIn4V2.BOOTLOADER_MODE_FIRMWARE_WAIT_FOR_ERASE_AND_REBOOT = 4
void BrickletIndustrialDigitalIn4V2.SetWriteFirmwarePointer(long pointer)
Parameters:
  • pointer – Type: long, Unit: 1 B, Range: [0 to 232 - 1]

Sets the firmware pointer for WriteFirmware(). 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.

byte BrickletIndustrialDigitalIn4V2.WriteFirmware(byte[] data)
Parameters:
  • data – Type: byte[], Length: 64, Range: [0 to 255]
Returns:
  • status – Type: byte, Range: [0 to 255]

Writes 64 Bytes of firmware at the position as written by SetWriteFirmwarePointer() 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.

void BrickletIndustrialDigitalIn4V2.WriteUID(long uid)
Parameters:
  • uid – Type: long, Range: [0 to 232 - 1]

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.

long BrickletIndustrialDigitalIn4V2.ReadUID()
Returns:
  • uid – Type: long, Range: [0 to 232 - 1]

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

Constants

int BrickletIndustrialDigitalIn4V2.DEVICE_IDENTIFIER

This constant is used to identify a Industrial Digital In 4 Bricklet 2.0.

The GetIdentity() function and the IPConnection.EnumerateCallback callback of the IP Connection have a deviceIdentifier parameter to specify the Brick's or Bricklet's type.

string BrickletIndustrialDigitalIn4V2.DEVICE_DISPLAY_NAME

This constant represents the human readable name of a Industrial Digital In 4 Bricklet 2.0.
