Command Structure

The common options of the call and dispatch commands are documented here. The specific command structure is shown below.

tinkerforge call industrial-counter-bricklet [<option>..] <uid> <function> [<argument>..]
Parameters:
  • <uid> – Type: String
  • <function> – Type: String

The call command is used to call a function of the Industrial Counter Bricklet. It can take several options:

  • --help shows help for the specific call command and exits
  • --list-functions shows a list of known functions of the Industrial Counter Bricklet and exits
tinkerforge dispatch industrial-counter-bricklet [<option>..] <uid> <callback>
Parameters:
  • <uid> – Type: String
  • <callback> – Type: String

The dispatch command is used to dispatch a callback of the Industrial Counter Bricklet. It can take several options:

  • --help shows help for the specific dispatch command and exits
  • --list-callbacks shows a list of known callbacks of the Industrial Counter Bricklet and exits
tinkerforge call industrial-counter-bricklet <uid> <function> [<option>..] [<argument>..]
Parameters:
  • <uid> – Type: String
  • <function> – Type: String

The <function> to be called can take different options depending of its kind. All functions can take the following options:

  • --help shows help for the specific function and exits

Getter functions can take the following options:

  • --execute <command> shell command line to execute for each incoming response (see section about output formatting for details)

Setter functions can take the following options:

  • --expect-response requests response and waits for it

The --expect-response option for setter functions allows to detect timeouts and other error conditions calls of setters as well. The device will then send a response for this purpose. If this option is not given for a setter function then no response is sent and errors are silently ignored, because they cannot be detected.

tinkerforge dispatch industrial-counter-bricklet <uid> <callback> [<option>..]
Parameters:
  • <uid> – Type: String

  • 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.

tinkerforge call industrial-counter-bricklet <uid> set-status-led-config <config>
Parameters:
  • <config> – Type: Int, Range: See symbols, Default: 3
Output:
  • no output

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.

The following symbols are available for this function:

For <config>:

  • status-led-config-off = 0
  • status-led-config-on = 1
  • status-led-config-show-heartbeat = 2

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

Callback Configuration Functions

tinkerforge call industrial-counter-bricklet <uid> set-all-counter-callback-configuration <period> <value-has-to-change>
Parameters:
  • <period> – Type: Int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • <value-has-to-change> – Type: Bool, Default: false
Output:
  • no output

The period is the period with which the all-counter 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.

tinkerforge call industrial-counter-bricklet <uid> get-all-counter-callback-configuration
Output:
  • period – Type: Int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • value-has-to-change – Type: Bool, Default: false

Returns the callback configuration as set by set-all-counter-callback-configuration.

tinkerforge call industrial-counter-bricklet <uid> set-all-signal-data-callback-configuration <period> <value-has-to-change>

  • <value-has-to-change> – Type: Bool, Default: false
Output:
  • no output

The period is the period with which the all-signal-data 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.

tinkerforge call industrial-counter-bricklet <uid> get-all-signal-data-callback-configuration
Output:
  • period – Type: Int, Unit: 1 ms, Range: [0 to 232 - 1], Default: 0
  • value-has-to-change – Type: Bool, Default: false

Returns the callback configuration as set by set-all-signal-data-callback-configuration.

Callbacks

Callbacks can be used to receive time critical or recurring data from the device:

tinkerforge dispatch industrial-counter-bricklet <uid> example

The available callbacks 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.

tinkerforge dispatch industrial-counter-bricklet <uid> all-counter
Output:
  • counter – Type: Int Array, Length: 4, Range: [-247 to 247 - 1]

This callback is triggered periodically according to the configuration set by set-all-counter-callback-configuration.

The parameters are the same as get-all-counter.

tinkerforge dispatch industrial-counter-bricklet <uid> all-signal-data
Output:
  • duty-cycle – Type: Int Array, Length: 4, Unit: 1/100 %, Range: [0 to 10000]
  • period – Type: Int Array, Length: 4, Unit: 1 ns, Range: [0 to 264 - 1]
  • frequency – Type: Int Array, Length: 4, Unit: 1/1000 Hz, Range: [0 to 232 - 1]
  • value – Type: Bool Array, Length: 4

This callback is triggered periodically according to the configuration set by set-all-signal-data-callback-configuration.

The parameters are the same as get-all-signal-data.

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.

tinkerforge call industrial-counter-bricklet <uid> set-bootloader-mode <mode>
Parameters:
  • <mode> – Type: Int, Range: See symbols
Output:
  • status – Type: Int, Range: See symbols

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 symbols are available for this function:

For <mode>:

  • bootloader-mode-bootloader = 0
  • bootloader-mode-firmware = 1
  • bootloader-mode-bootloader-wait-for-reboot = 2
  • bootloader-mode-firmware-wait-for-reboot = 3
  • bootloader-mode-firmware-wait-for-erase-and-reboot = 4

For status:

  • bootloader-status-ok = 0
  • bootloader-status-invalid-mode = 1
  • bootloader-status-no-change = 2
  • bootloader-status-entry-function-not-present = 3
  • bootloader-status-device-identifier-incorrect = 4
  • bootloader-status-crc-mismatch = 5
tinkerforge call industrial-counter-bricklet <uid> get-bootloader-mode
Output:
  • mode – Type: Int, Range: See symbols

Returns the current bootloader mode, see set-bootloader-mode.

The following symbols are available for this function:

For mode:

  • bootloader-mode-bootloader = 0
  • bootloader-mode-firmware = 1
  • bootloader-mode-bootloader-wait-for-reboot = 2
  • bootloader-mode-firmware-wait-for-reboot = 3
  • bootloader-mode-firmware-wait-for-erase-and-reboot = 4
tinkerforge call industrial-counter-bricklet <uid> set-write-firmware-pointer <pointer>
Parameters:
  • <pointer> – Type: Int, Unit: 1 B, Range: [0 to 232 - 1]
Output:
  • no output

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.

tinkerforge call industrial-counter-bricklet <uid> write-firmware <data>
Parameters:
  • <data> – Type: Int Array, Length: 64, Range: [0 to 255]
Output:
  • status – Type: Int, Range: [0 to 255]

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.

tinkerforge call industrial-counter-bricklet <uid> write-uid <uid>
Parameters:
  • <uid> – Type: Int, Range: [0 to 232 - 1]
Output:
  • no output

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.

tinkerforge call industrial-counter-bricklet <uid> read-uid
Output:
  • uid – Type: Int, Range: [0 to 232 - 1]

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