MATLAB: When I create an object for an unsigned char in the program, why do I get a STRING/ RSTRING class object as a ‘signed char’

Question

I am using a C6000 series board.

Answer 1

To work around this issue, you can convert the object to 'unsigned'.

The following example shows how to do this:

In CCS, if you have the following:

unsigned char ScalarVal = 4;

and you create a link for it in MATLAB:

obj = createobj
(CCS_Obj,'ScalarVal')      % Note: obj.represent='signed'

You can then convert the object to 'unsigned char' by executing the following command:

convert(obj,'signed char') % Note: obj.represent='unsigned'
