blfwrite

Write data to Vector BLF-file

Syntax

blfwrite(blfFile,data,chanID,prot)

Description

blfwrite(blfFile,data,chanID,prot) writes the specified timetables in data to the specified BLF-file. The function allows writing only to new files, so you cannot overwrite existing files or data.

Note

Support for BLF-files is limited to only CAN and CAN FD protocols on Windows^® operating systems. See File Format Limitations.

Examples

Write Data to a BLF-File

Write timetables of data to specified channels.

Write one data set to a single channel.

blfwrite("newfile.blf",data,1,"CAN")

Write two data sets to the same channel.

blfwrite("newfile.blf",{data1,data2},[1,1],["CAN FD","CAN FD"])

Write two data sets to separate channels with different protocols.

blfwrite("newfile.blf",{data1,data2},[1,2],["CAN","CAN FD"])

Input Arguments

blfFile — Path to BLF-file

string | char

Path to BLF-file to write, specified as a string or character vector. The value can specify a file in the current folder, or a relative or full path name.

Example: "MultipleChannelFile.blf"

Data Types: string | char

data — Data to write to BLF-file

timetable

Data to write to BLF-file, specified as a timetable or cell array of timetables. You can write multiple tables for the same channel if the protocol is the same.

Data Types: timetable

chanID — Channel IDs

numeric

Channel IDs, specified as a numeric scalar or array value, identifying the channels on which the data is written.

Example: [1,2,4]

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

prot — Message protocol

"CAN""CAN FD"

Message protocol, specified as "CAN", "CAN FD". When writing multiple sets of data, specify protocol as an array of strings corresponding to the data sets being written.

Example: ["CAN","CAN FD","CAN"]

Data Types: char | string
