When using the screen reader on either a computer or a mobile device, connecting a braille display to it already converts any text to braille. That's the entire purpose of the braille display apart from being a braille entry keyboard. There is a mobile application called KN FB reader which does optical character recognition; take a picture of a document or some text and it does a fairly decent job at converting the image to text that can be read by a screen reader and subsequently sent to a braille display.
Are you looking for some kind of converter that turns text into visual braille for sighted people?
