how to convert numeric to string in Simulink?

hello,

I have a problem with converting nemeric to string in simulink.

I want to send a message 'M+' through RS232(depace).

so I know the M is 77, + is 43 in ascii code.

using constant,convert block and display block,i want to check the result.

but it's not easy to work in simulink... (I've change the block condition , unit 16)

please advice to me.

According to my search, strings are not a valid datatype for Simulink. You could log the uint-signal which represents your ASCII code and work with it in MATLAB (there you can simply use i.e. char(77) to get 'M').
