Read binary data

Block Screenshot


This block allows user to read data in a C file. Output record selection and Time record Selection allows the user to select data among file records. Each call to the block advance one record in the file.

Dialog box

  • Time record selection

    an empty matrix or a positive integer.

    If an integer i is given the i th element of the read record is assumed to be the date of the output event.

    If empty no output event exists.

    Properties : Type 'vec' of size -1

  • Outputs record selection

    a vector of positive integer.

    : The th element of the read record gives the value of output.

    Properties : Type 'vec' of size -1

  • Input file name

    a character string defining the path of the file.

    Properties : Type 'str' of size 1

  • Input Format

    a character string defining the format to use.

    Properties : Type 'str' of size 1

  • Record size

    The file is supposed to be formed by a sequence of data with same format.

    These data are organized in a sequence of record each of them containing Record size data.

    Properties : Type 'vec' of size 1

  • Buffer size

    To improve efficiency it is possible to buffer the input data. Read on the file is only done after each Buffer size call to the block.

    Properties : Type 'vec' of size 1

  • Initial record index

    a scalar. This fixes the first record of the file to use.

    Properties : Type 'vec' of size 1

  • Swap mode 0/1

    WithSwap mode=1 the file is supposed to be coded in "little endian IEEE format" and data are swaped if necessary to match the IEEE format of the processor. IfSwap mode=0 then automatic bytes swap is disabled.

    Properties : Type 'vec' of size 1

Default properties

  • always active: no

  • direct-feedthrough: no

  • zero-crossing: no

  • mode: no

  • regular outputs:

    - port 1 : size [1,1] / type 1

  • number/sizes of activation inputs: 1

  • number/sizes of activation outputs: 0

  • continuous-time state: no

  • discrete-time state: yes

  • object discrete-time state: no

  • name of computational function: readc

Interfacing function

  • SCI/modules/scicos_blocks/macros/Sources/READC_f.sci

Computational function

  • SCI/modules/scicos_blocks/src/c/readc.c (Type 2)
