how to convert a number into an ascii code

[Newlearner]

Hi,:
I just start to use Labview. i plan to use the labview to talk to Rs232. here is my question:
i have unsigned 8 bits number, i plan to convert the number into a letter so that i can send it to RS232. for example, i have unsinged number 85, i want to convert it into "U" since "U" is the corresponding letter of ascii code 85,

can you please tell me how i should do it,

thank you,

Make sure the unsigned number is 8 bit (U8), then use typecast.

Hi, Christian:

Thank you for your message!

i used the type cast, but it seems VISA write can not recognize it, what is the problem?

[Newlearner]

Sorry, see the image

[altenbach]

I don't see any visa write in your image.

sorry, it seems i can get the correct character of the corresponding ascii code. however, it seems input is wrong. see the attached error message

[altenbach]

The error is in "cofigure serial port", way before the string operation. Make sure all inputs there are valid. How do you define the visa resource?

Thank you for your message.

it seems i did not define the  com port correctly
