Perl - RED Brick

This is the description of the Perl API bindings for the RED Brick. General information and technical specifications for the RED Brick are summarized in its hardware description.

An installation guide for the Perl API bindings is part of their general description.

Examples

The example code below is Public Domain (CC0 1.0).

API

Generally, every subroutine of the Perl bindings can report an error as Tinkerforge::Error object via croak(). The object has a get_code() and a get_message() subroutine. There are different error code:

  • Error->ALREADY_CONNECTED = 11
  • Error->NOT_CONNECTED = 12
  • Error->CONNECT_FAILED = 13
  • Error->INVALID_FUNCTION_ID = 21
  • Error->TIMEOUT = 31
  • Error->INVALID_PARAMETER = 41
  • Error->FUNCTION_NOT_SUPPORTED = 42
  • Error->UNKNOWN_ERROR = 43

All methods listed below are thread-safe.

Note

The API documentation for the RED Brick is currently incomplete.

The RED Brick API is meant to be used by the Brick Viewer to implement the offered functionality (getting status information, managing programs etc.). Normal users will not need to use this API, it may only be interesting for power users.

FIXME: explain sessions

The RED Brick API operates on reference counted objects (strings, lists, files, directories, processes and programs) that are identified by their 16bit object ID. Functions that allocate or return an object ID (e.g. allocate_string() and get_next_directory_entry()) increase the reference count of the returned object. If the object is no longer needed then release_object() has to be called to decrease the reference count of the object again. In contrast to allocation and getter functions, the reference count for an object returned by a callback is not increased and release_object() must not be called for such an object in response to a callback.

There are functions (e.g. get_file_info()) that only return valid objects under certain conditions. This conditions are documented for the specific functions. For invalid objects release_object() must not be called.

There are also function (e.g. set_program_stdio_redirection()) that have conditionally unused object parameters. Under which conditions an object parameter is unused is documented for the specific functions. For unused object parameters 0 has to be passed as object ID.

The RED Brick API is more complex then the typical Brick API and requires more elaborate error reporting than the TCP/IP protocol can provide with its 2bit error code. Therefore, almost all functions of the RED Brick API return an 8bit error code. Possible error codes are:

  • Success = 0
  • UnknownError = 1
  • InvalidOperation = 2
  • OperationAborted = 3
  • InternalError = 4
  • UnknownSessionID = 5
  • NoFreeSessionID = 6
  • UnknownObjectID = 7
  • NoFreeObjectID = 8
  • ObjectIsLocked = 9
  • NoMoreData = 10
  • WrongListItemType = 11
  • ProgramIsPurged = 12
  • InvalidParameter = 128 (EINVAL)
  • NoFreeMemory = 129 (ENOMEM)
  • NoFreeSpace = 130 (ENOSPC)
  • AccessDenied = 131 (EACCES)
  • AlreadyExists = 132 (EEXIST)
  • DoesNotExist = 133 (ENOENT)
  • Interrupted = 134 (EINTR)
  • IsDirectory = 135 (EISDIR)
  • NotADirectory = 136 (ENOTDIR)
  • WouldBlock = 137 (EWOULDBLOCK)
  • Overflow = 138 (EOVERFLOW)
  • BadFileDescriptor = 139 (EBADF)
  • OutOfRange = 140 (ERANGE)
  • NameTooLong = 141 (ENAMETOOLONG)
  • InvalidSeek = 142 (ESPIPE)
  • NotSupported = 143 (ENOTSUP)
  • TooManyOpenFiles = 144 (EMFILE)

If a function returns an error code other than Success then its other return values (if any) are invalid and must not be used.

The error code InvalidOperation is returned if the requested operation cannot be performed because the current state of the object does not allow it. For example, trying to append an item to a full list object or trying to undefine an already undefined program.

The error code NotSupported is returned if the requested operation can never be performed. For example, trying to append a list object to itself, trying to get the name of a file object with type Pipe or trying to create a directory non-recursively with more than the last part of the directory name referring to non-existing directories.

String objects store UTF-8 encoded data.

BrickRED->get_api_version()
Return type:[int, int, int]

Returns the version of the API definition (major, minor, revision) 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.

BrickRED->get_response_expected($function_id)
Parameters:$function_id -- int
Return 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 set_response_expected(). 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 send and errors are silently ignored, because they cannot be detected.

See set_response_expected() for the list of function ID constants available for this function.

BrickRED->set_response_expected($function_id, $response_expected)
Parameters:
  • $function_id -- int
  • $response_expected -- bool
Return type:

undef

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

The following function ID constants are available for this function:

  • BrickRED->FUNCTION_EXPIRE_SESSION_UNCHECKED = 3
  • BrickRED->FUNCTION_RELEASE_OBJECT_UNCHECKED = 6
  • BrickRED->FUNCTION_READ_FILE_ASYNC = 21
  • BrickRED->FUNCTION_WRITE_FILE_UNCHECKED = 24
  • BrickRED->FUNCTION_WRITE_FILE_ASYNC = 25
BrickRED->set_response_expected_all($response_expected)
Parameters:$response_expected -- bool
Return type:undef

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

BrickRED->get_identity()
Return type:[string, string, char, [int, int, int], [int, int, int], int]

Returns the UID, the UID where the Brick is connected to, the position, the hardware and firmware version as well as the device identifier.

The position can be '0'-'8' (stack position).

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

The returned array contains the elements uid, connected_uid, position, hardware_version, firmware_version and device_identifier.

Callback Configuration Functions

BrickRED->register_callback($id, $callback)
Parameters:
  • $id -- int
  • $callback -- string
Return type:

undef

Registers the given $function name with the given $callback_id.

The available callback IDs with corresponding function signatures are listed below.

Callbacks

Callbacks can be registered to receive time critical or recurring data from the device. The registration is done with the register_callback() function of the device object. The first parameter is the callback ID and the second parameter the callback function name:

sub my_callback
{
    print "@_[0]";
}

$red->register_callback(BrickRED->CALLBACK_EXAMPLE, 'my_callback')

The callback function will be called from an internal thread of the IP Connection. In contrast to many other programming languages, variables are not automatically shared between threads in Perl. If you want to share a global variable between a callback function and the rest for your program it has to be marked as :shared. See the documentation of the threads::shared Perl module for more details.

The available constants with inherent number and type of parameters 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.

BrickRED->CALLBACK_ASYNC_FILE_READ
Parameters:
  • $file_id -- int
  • $error_code -- int
  • @buffer -- [int, int, ..57x.., int]
