write a string by (visa write) per character

NBChaaben — Thu, 23 Sep 2010 11:37:13 GMT

Hello,
I want to know how to write a string using "visa write" character by character and read later with a "visa read"
I tried with a for loop, delay, and the object "spreadsheet string to array" and I failed to do so, I think I did not clearly specify its inputs (format string and string spreadsheet )
Please give me an example or clarify me how to do it.
Thank you in advance

Your "Spreadsheet String To Array" functions needs a correct format string.

Try %s

The usual and easy way to use Visa write is to write a full string at once, and not character by character. Remember to open and close the visa port before trying to send and recieve anything.
