Iam unable to read HEX values from xls file

[embedded systems engineer]

Hi all,
please go through the attachment. The programme will read the data from xls file and everysecond it will be updated. if you observe the DISCRETE column in profile1.xls , it contains FF hex data, but when i run the programme the corresponding A9 will be showning 0 instead of FF , WHY?????/
If i replaced FF with decimal data then corresponding A9( see front panel) will be updated the decimal value.why i couldnt be able to read hex values from xls file.


Thanks in advance

The function "read from spreadsheet file" assumes all fields be formatted as floating point (%f). You should probably read the entire file as raw string then parse it yourself, each column with the appropriate format.
