Write and Read Character Data from Binary Files in Simulink
The Binary File Writer and Binary File Reader blocks do not support writing and reading characters. As a workaround, cast character data to one of the built-in data types and write the integer data. After the reader reads the data, convert the data to a character using the char function.
Write the Character Data
Cast the character data, 'binary_file' into uint8 using the cast function.
data = 'binary_file';
Write the cast data to the data file myCharFile.dat.
writeModel = fullfile(matlabroot,'examples','dsp','writeCharData'); open_system(writeModel) sim(writeModel)
Read the uint8 Data
Specify the reader to read the cast data as uint8 data.
readModel = fullfile(matlabroot,'examples','dsp','readCharData'); open_system(readModel) sim(readModel);
charData = char(readerData);
Verify that the writer data is same as the reader data. By default, the reader returns the data in a column-major format.
