GUI COMPOSER ASCII Format

Displaying a variable in ASCII format is not natively supported like some other formats like hex. However, you can manipulate the displayed data by creating a preprocessing function that is applied to the value of the variable to be displayed.

Please see this post for more details on how to create and edit a preprocessing function. In that example, the variable format is being converted to binary. To convert to ASCII you could try the String.fromCharCode function (which I found by searching the internet).

function converttoascii( valueFromTarget) {

                return String.fromCharCode(valueFromTarget);

}
