Hello friends, Ref: Code composer studio 3.1 for C6416. I wish to know how to save floating point variables in floating format to a file using 'File-> Data-> Save' option in CCS. (I know how to save the integers and read it through Matlab). For example the value 215.3560 must come in the file as 215.3560 only. Not as a Hexadecimal number. Is there any provision for this in CCS. Or
